The best pet calming supplements depend on your pet’s stress triggers, preferred format, and tolerance for active ingredients. Purina Pro Plan Veterinary Supplements Calming Care is my best overall pick for buyers who want a daily supplement with a distinct, non-chew format; Greenies Calming Chews stand out for dogs who readily take treats, while Billion Pets Hemp Oil offers a flexible option for households with dogs and cats. The main tradeoffs are chew convenience versus liquid flexibility, and simple routines versus formulas with more active ingredients. Supplements may support calm behavior, but they are not a substitute for veterinary care when anxiety is severe or sudden. Read on for the full comparison and advice on matching a format to your pet.

Key Takeaways
- Format is a major separator: Most picks are dog chews, while Purina Pro Plan Calming Care is a powder and Billion Pets, Charlie & Buddy, and Rescue Remedy are liquid options.
- Purina Pro Plan Calming Care leads for a routine-based approach: Its powder format gives it a distinct role among the treat-heavy lineup, but it may not suit pets that reject supplements mixed into food.
- Greenies is the easiest treat-style starting point: Its familiar chew format makes it a practical choice for dogs that already accept treats, though it is dog-specific and less flexible than oils.
- Hemp appears across many picks, so it is not a useful shortcut by itself: Compare the full ingredient panel, serving directions, and species labeling rather than choosing by one ingredient name.
- Households with cats have fewer clear options: Billion Pets and Charlie & Buddy are labeled for dogs and cats, but buyers should verify species-specific directions and check with a veterinarian before use.

More Details on Our Top Picks
Greenies Calming Chews for Dogs, Chicken Flavor, 40 Count
Greenies is a straightforward choice for dog owners who want calming support in a chicken-flavored chew without a long ingredient list. Its L-tryptophan and L-theanine are intended to support relaxation during normal or occasional stress, while real chicken gives the product a familiar flavor cue. Compared with Native Pet Calming Chews, which add melatonin, hemp seed, and casein, Greenies keeps its listed calming ingredients simpler. That may suit buyers who prefer fewer named actives, but it also means the product is described for occasional stress rather than as a broad solution for more persistent anxiety. The 40-count supply is smaller than NaturVet Quiet Moments’ 180 chews, and the product information conflicts on form: it calls these chews but lists the item form as a capsule. I’d check the packaging for the actual format before buying.
Pros:- Combines L-tryptophan and L-theanine for calming support
- Made with real chicken and no artificial flavors, colors, or fillers
- Carries the National Animal Supplement Council Quality Seal
- Listed as corn-free, dairy-free, and rawhide-free
Cons:- The product information describes occasional stress support, not treatment for severe anxiety
- Form is inconsistent: described as chews but listed as a capsule
- A 40-count supply is smaller than NaturVet Quiet Moments’ 180-chew jar
Best for: Dog owners seeking a chicken-flavored option with L-tryptophan and L-theanine for normal or occasional stress.
Not ideal for: Owners looking for a clearly specified capsule or chew format, a larger-count supply, or support specifically described for severe anxiety.
- Flavor:Chicken
- Listed item form:Capsule
- Count:40
- Listed ingredients:L-tryptophan, L-theanine, real chicken
- Dog breed size:Medium
- Item weight:7.3 ounces
- Allergen information:Corn-free, dairy-free, rawhide-free
- Made in:USA
Our verdict“Choose Greenies if you want a chicken-flavored, comparatively simple calming formula for occasional stress and can confirm the format before ordering.”
Native Pet Calming Chews for Dogs, Air-Dried, 30 Chews
Native Pet is the most event-oriented chew in this group: its description specifically names thunderstorms, fireworks, travel, and routine changes, while also allowing for daily use. The air-dried format avoids fillers and artificial flavors, and the formula combines hemp seed, melatonin, L-theanine, and casein. That makes it a broader ingredient blend than Greenies Calming Chews, which lists L-tryptophan and L-theanine with chicken. The tradeoff is that Native Pet’s supplied information gives no dosage guidance, so buyers have less detail for planning use around a particular event. It also advises veterinary consultation for puppies or dogs taking medication. I’d favor this over Purina Pro Plan Calming Care when a chew format and named stressful situations are the priority; Purina instead uses a specified probiotic powder.
Pros:- Names common stress situations including thunderstorms, fireworks, and travel
- Air-dried chews are described as free of fillers and artificial flavors
- Combines hemp seed, melatonin, L-theanine, and casein
- Made in the USA and carries the NASC Quality Seal
Cons:- The supplied product details do not include dosage guidance
- Veterinary consultation is advised for puppies and dogs taking medication
- The 30-chew count is lower than the counts listed for Greenies and NaturVet
Best for: Owners looking for an air-dried chew to use during named stressors such as storms, fireworks, travel, or routine changes.
Not ideal for: Owners who need clear dosage directions, or those giving supplements to a puppy or a dog taking medication without veterinary guidance.
- Quantity:30 chews
- Format:Air-dried chews
- Active ingredients:Hemp seed, melatonin, L-theanine, and casein
- Hemp detail:Non-psychoactive hemp seed; no THC
- Made in:USA
- Certification:NASC Quality Seal
- Described use:Daily use or before stressful events
Our verdict“Pick Native Pet if you want an air-dried chew aimed at specific stressful events and are comfortable confirming dosage with the label or your veterinarian.”
Hemp Calming Chews for Dogs, 240 Treats
With 240 chicken-flavored treats, this is the clear pick for buyers who put supply size first. Its listed ingredients—hemp, valerian root, chamomile, and melatonin—cover more named calming components than Greenies Calming Chews, whose supplied formula lists L-tryptophan and L-theanine. The product is described for situations such as travel, vet visits, thunderstorms, and separation, and it is intended for dogs of all ages and sizes. That breadth makes it appealing for households with more than one dog or frequent occasions to plan for, but the details stop short of ingredient amounts and dosage guidance. Compared with NaturVet Quiet Moments, which provides a smaller 180-chew count and a different ingredient mix, this option offers more treats but less formulation detail. I’d want the label’s directions before relying on it for regular use.
Pros:- Large 240-treat supply
- Lists hemp, valerian root, chamomile, and melatonin
- Described for stressors including travel, vet visits, storms, and separation
- Veterinarian-formulated and made in the USA
Cons:- The supplied details do not state ingredient amounts
- No dosage guidance is included in the product information
- The broad all-ages-and-sizes claim does not replace checking label directions for an individual dog
Best for: Owners who want a large supply of chicken-flavored calming treats for dogs of varied ages and sizes, subject to label directions.
Not ideal for: Buyers who need stated active-ingredient amounts or dosage guidance before choosing a supplement.
- Treat count:240
- Flavor:Chicken
- Item weight:0.56 kg
- Ingredients mentioned:Hemp, valerian root, chamomile, melatonin
- Formulated by:Veterinarians
- Made in:USA
- Intended for:Dogs of all ages and sizes
- Described uses:Anxiety, behavior, and calming support
Our verdict“Choose this high-count option if treat quantity and a multi-ingredient blend matter more to you than having dosage and ingredient amounts stated in the supplied details.”
NaturVet Quiet Moments Calming Plus Hemp Dog Supplement, 180 Soft Chews
NaturVet Quiet Moments suits owners who want a soft-chew format and a resealable jar with more than a short event-only supply. Its 180 chews are a useful middle ground between the 40-count Greenies product and the 240-treat Hemp Calming Chews. The listed blend—melatonin, ginger, L-tryptophan, and thiamin—differs from Native Pet Calming Chews, which includes L-theanine, casein, and hemp seed instead. NaturVet’s description specifically names separation, storms, grooming, and travel, giving buyers practical examples of intended use. But the supplied information does not include dosage directions or evidence of individual results, so I would not treat the larger jar as a reason to use it more often than the label recommends. It is listed for dogs over 12 weeks, a narrower age statement than the all-ages claim on the 240-treat option.
Pros:- 180 soft chews in a resealable jar
- Names separation, storms, grooming, and travel as intended stress situations
- Lists melatonin, ginger, L-tryptophan, and thiamin
- Made in the USA in a cGMP-compliant facility
Cons:- The supplied information does not provide dosage instructions
- Listed for dogs over 12 weeks, so it is not presented for younger puppies
- No effectiveness details are included in the product information
Best for: Owners of dogs over 12 weeks who prefer soft chews in a resealable jar and want a larger supply for recurring stress situations.
Not ideal for: Puppy owners whose dogs are under 12 weeks, or buyers who need dosage directions in the supplied product information.
- Product type:Dog calming supplement
- Form:Soft chews
- Quantity:180 chews
- Ingredients:Melatonin, ginger, L-tryptophan, thiamin
- Intended age:Dogs over 12 weeks
- Made in:USA
- Packaging:Resealable jar
- Facility detail:cGMP-compliant facility
Our verdict“Choose NaturVet if your dog is over 12 weeks and you want a resealable, 180-chew supply for recurring everyday stressors.”
Purina Pro Plan Veterinary Supplements Calming Care Dog Supplement, 30 Count
Purina Pro Plan Calming Care is the outlier here: instead of a chew built around a mix of calming ingredients, it provides a probiotic powder with a named strain and amount. Each packet lists 1 × 10^9 CFU of Bifidobacterium longum BL999 and is intended to support calm behavior and positive cardiac activity during stressful events. That specificity makes it easier to understand what the formula contains than the Hemp Calming Chews, which list several ingredients but provide no amounts in the supplied details. The format is also a meaningful tradeoff: buyers need to serve a powder packet rather than offer a treat. Compared with Native Pet Calming Chews, Purina’s description focuses on a probiotic approach and common routine stressors such as separation or unfamiliar visitors, not an event-ready chew blend. Individual results are not described, so I’d choose it for its distinct format and stated strain, not as a guaranteed response.
Pros:- Uses the named probiotic strain Bifidobacterium longum BL999
- States the probiotic amount per packet
- Targets stressors including separation, unfamiliar visitors, and routine changes
- Powder format offers an alternative to the roundup’s chews
Cons:- Powder packets may be less convenient than treats for some dogs
- The supplied details do not include individual-result or effectiveness information
- Only 30 packets are included
Best for: Dog owners who prefer a powder supplement and want a clearly named probiotic strain with a stated amount per packet.
Not ideal for: Owners whose dogs will not take supplements mixed as powder, or buyers seeking a chew-based blend with ingredients such as melatonin or hemp.
- Form:Powder supplement
- Count:30 packets
- Probiotic strain:Bifidobacterium longum BL999
- Probiotic amount:1 × 10^9 CFU per packet
- Intended use:Supports calm behavior and positive cardiac activity during stressful events
- Named stressors:Separation, unfamiliar visitors, and changes in routine
Our verdict“Pick Purina Pro Plan Calming Care if you want a powder with a specified probiotic strain and amount rather than a conventional calming chew.”
Calming Chews for Dogs with Hemp and Melatonin
This chicken-flavored chew combines hemp oil, valerian root, chamomile, and melatonin, giving it a broader ingredient mix than Veterinary Formula Smart Vitality Pet Calm Soft Chews, which lists L-theanine and L-tryptophan. Its stated uses—thunderstorms, travel, vet visits, and separation—make it a fit for owners seeking one chew for several predictable stressors. The product is veterinarian formulated and intended for dogs of all ages and sizes, although that broad suitability does not replace checking the label or asking a veterinarian about an individual dog. The main tradeoff is limited dosing information: no ingredient quantities or dosage details are supplied, so it is harder to judge strength or plan use. Choose it for its varied calming blend, not for transparent potency details.
Pros:- Combines hemp oil, valerian root, chamomile, and melatonin
- Names several common stress situations, including travel and thunderstorms
- Intended for dogs of all ages and sizes
- Veterinarian formulated and made in the USA
Cons:- Ingredient quantities and dosage details are not provided
- The supplied information includes no customer results or review content
Best for: Dog owners looking for a chicken-flavored, multi-ingredient chew for predictable stressors such as storms, travel, or vet visits.
Not ideal for: Owners who need clearly stated ingredient amounts and dosage guidance before choosing a calming supplement.
- Flavor:Chicken
- Ingredients:Hemp oil, valerian root, chamomile, melatonin
- Suitable for:Dogs of all ages and sizes
- Formulation:Veterinarian formulated
- Made in:USA
- Intended situations:Thunderstorms, travel, vet visits, and separation
Our verdict“Choose this chew if you want several calming ingredients aimed at event-related stress and can verify dosing details before use.”
Billion Pets Hemp Oil for Dogs and Cats
For a home with both cats and dogs, this flavorless hemp oil is more flexible than dog-only soft chews such as Pawzitive Pets Hemp Calming Chews. It can be given by dropper, mixed into food, or applied topically, so owners have several ways to work it into a routine. The formula is listed as organic hemp extract, with non-GMO and cruelty-free attributes, and it contains no xylitol. The tradeoff is that the product information gives no extract concentration, making it difficult to compare potency or understand how much hemp extract each serving supplies. It also claims support for mobility, digestion, and coat health alongside calmness, but the supplied details do not explain how those benefits are measured. I’d favor it for species flexibility and adjustable administration, not for a clearly quantified calming dose.
Pros:- Suitable for both dogs and cats
- Can be given by dropper, mixed with food, or applied topically
- Flavorless and listed as allergen-free
- Non-GMO, cruelty-free, and contains no xylitol
Cons:- Hemp extract concentration is not specified
- No dosage details are supplied
- Calming and other wellness benefits are not supported by outcome details in the provided information
Best for: Dog-and-cat households seeking one flavorless hemp oil that can be added to food or given by dropper.
Not ideal for: Buyers who want a clearly stated extract concentration, a measured chew serving, or a dog-specific formula.
- Flavor:Flavorless
- Form:Oil
- Suitable for:Dogs and cats
- Volume:30 ml
- Item weight:1 ounce
- Ingredients:Organic hemp extract
- Other attributes:Non-GMO, cruelty-free, contains no xylitol
Our verdict“Pick this oil for flexible use across cats and dogs, but skip it if you need a transparent extract strength or serving guide.”
Veterinary Formula Smart Vitality Pet Calm Soft Chews for Dogs, 60 Count
Daily or as-needed use is the distinguishing point here: Veterinary Formula Smart Vitality Pet Calm Soft Chews are presented for both recurring routines and specific situations such as grooming, travel, fireworks, or vet visits. Its listed actives, L-theanine and L-tryptophan, also give it a different profile from Calming Chews for Dogs with Hemp and Melatonin, which leans on botanicals and melatonin. The NASC Quality Seal and cGMP-certified facility provide useful manufacturing context, though they do not tell buyers the serving dose or predict an individual dog’s response. The listing also conflicts on form, calling the product a soft chew in the title and description but a tablet in product information. I’d put it ahead for owners wanting a stated flexible-use routine, but not for anyone who needs unambiguous form and dosing details.
Pros:- Designed for daily or as-needed use
- Contains L-theanine and L-tryptophan
- Lists common situations including grooming, travel, fireworks, and vet visits
- Made in a cGMP-certified facility and carries the NASC Quality Seal
Cons:- Dosage details are not provided in the supplied information
- Product information conflicts on whether the form is a soft chew or tablet
- Lists fish allergen information, which may not suit dogs with relevant sensitivities
Best for: Dog owners seeking a vet-formulated option described for both regular calming support and specific events.
Not ideal for: Buyers who need clear dosage instructions or certainty about whether the product is a chew or tablet.
- Flavor:Pork
- Form:Soft chews in title and description; listed as tablet in product information
- Active ingredients:L-theanine, L-tryptophan
- Count:60 soft chews
- Intended use:Calming support
- Dog size:All sizes, including small and medium
- Allergen information:Fish
- Manufacturing and quality:Made in USA; cGMP-certified facility; NASC Quality Seal
Our verdict“Choose this if you want a flexible-use, L-theanine and L-tryptophan formula, provided the label clarifies form and dosing for your dog.”
Charlie & Buddy Hemp Oil for Dogs and Cats
Charlie & Buddy pairs hemp seed oil extract with omega 3, 6, and 9 fatty acids, plus vitamins E and B, so its pitch extends beyond calmness to skin, coat, joint, and digestive support. That broader nutrient profile sets it apart from Billion Pets Hemp Oil for Dogs and Cats, which lists organic hemp extract as its ingredient and emphasizes flexible application. This natural-flavor oil suits dogs and cats of all breeds and sizes, and the listed allergen exclusions may help some households screen it. The tradeoff is that the supplied details give neither serving guidance nor quantities for the active ingredients. Its wide range of stated benefits also does not establish how strongly it supports any one goal. I’d choose it for a multi-purpose oil profile, not as the most clearly specified calming option.
Pros:- Suitable for dogs and cats of all breeds and sizes
- Includes omega 3, 6, and 9 fatty acids, vitamin E, and vitamin B
- Described as supporting calm behavior as well as joint and skin-and-coat health
- Listed as free of codfish, dairy, gluten, and soy
Cons:- Dosage information is not provided
- Ingredient quantities are not stated
- The supplied product information does not substantiate its range of wellness claims with outcome details
Best for: Owners of dogs or cats who want an oil combining hemp seed oil, fatty acids, and vitamins alongside calming support.
Not ideal for: Buyers focused on a defined calming dose or those who prefer a formula with ingredient quantities and serving instructions.
- Flavor:Natural
- Form:Oil
- Active ingredients:Hemp seed oil extract, omega 3, 6, and 9 fatty acids, vitamin E, vitamin B
- Item weight:2.88 ounces
- Suitable for:Dogs and cats of all breeds and sizes
- Specific uses:Calming support, immune support, joint health, skin and coat health
- Allergen information:Codfish-free, dairy-free, gluten-free, soy-free
Our verdict“Choose this oil if you want calming support packaged with fatty acids and vitamins for a dog or cat, rather than a narrowly specified calming formula.”
Pawzitive Pets Hemp Calming Chews for Dogs, 120 Soft Treats
With 120 soft treats, Pawzitive Pets offers a larger stated supply than Veterinary Formula Smart Vitality Pet Calm Soft Chews, which comes in a 60-count package. Its blend includes hemp seed oil, melatonin, chamomile, and L-tryptophan, and the product is aimed at recognizable stress triggers such as fireworks, travel, vet visits, and separation. That makes it a straightforward dog-only treat option for owners who want a substantial count on hand. The drawback is that count alone does not show how long a package lasts: no serving instructions or ingredient quantities are supplied. Compared with the veterinarian-formulated Veterinary Formula option, this listing also gives less manufacturing and quality detail beyond being made in the USA. It suits buyers prioritizing a larger treat count, but not those choosing by transparent dosage information.
Pros:- Provides 120 soft treats
- Combines hemp seed oil, melatonin, chamomile, and L-tryptophan
- Aimed at stressors including travel, vet visits, separation, fireworks, and thunderstorms
- Made in the USA
Cons:- Ingredient quantities and dosage information are not provided
- The supplied product information includes no customer review content
- Does not list the manufacturing or quality details provided for Veterinary Formula Smart Vitality
Best for: Dog owners who want a larger-count supply of soft calming treats for recurring or predictable stressful situations.
Not ideal for: Owners who need ingredient amounts, serving instructions, or more detailed manufacturing information to compare formulas.
- Quantity:120 soft treats
- Form:Soft treats
- Key ingredients:Hemp seed oil, melatonin, chamomile, L-tryptophan
- Suitable for:Dogs
- Intended use:Calming and stress relief
- Intended situations:Travel, vet visits, separation, fireworks, and thunderstorms
- Made in:USA
Our verdict“Choose Pawzitive Pets for its 120-treat format and multi-ingredient blend, but look elsewhere if dosing transparency is your priority.”
BARK&SPARK Hemp Calming Treats for Dogs
BARK&SPARK keeps the format straightforward: soft, flavored treats combine hemp and melatonin for dogs who resist pills. The stated use cases—storms, fireworks, and travel—make this a situational option rather than a clearly specified daily routine supplement. Compared with Zesty Paws Calming Chews, which lists a broader blend of ingredients, BARK&SPARK offers fewer named components, but its description also leaves out their amounts and any serving guidance. That makes it harder to judge fit for a particular dog or plan use around an event. I’d shortlist it for an owner who prioritizes a treat format and a compact ingredient description, but skip it if transparent dosing or a more detailed formula is part of your decision.
Pros:- Soft treat format may be easier to give than a pill
- Contains hemp and melatonin
- Description identifies travel, storms, and fireworks as intended situations
Cons:- No ingredient amounts or dosage information are provided
- The supplied information does not substantiate effectiveness claims
Best for: Dog owners seeking a soft, flavored, pill-free option for occasional stress around travel, storms, or fireworks.
Not ideal for: Owners who need listed ingredient amounts, serving instructions, or a clearly detailed formula before choosing a supplement.
- Form:Soft treats
- Ingredients mentioned:Hemp and melatonin
- Intended use:Support relaxation during stressful situations
- Situations mentioned:Travel, storms, and fireworks
- Administration style:Pill-free treat
- Dosage information:Not provided
Our verdict“Choose BARK&SPARK if a soft, pill-free treat is your priority, but pass if you need clear dosing or ingredient amounts.”
Zesty Paws Calming Chews for Dogs, Peanut Butter, 90 Count
Zesty Paws stands out for ingredient variety: its peanut-butter chews list L-theanine, ashwagandha, valerian root, passionflower, hemp seed powder, magnesium citrate, L-tryptophan, and ginger. That gives ingredient-conscious buyers more to evaluate than the shorter descriptions for BARK&SPARK Hemp Calming Treats or Nutri-Vet Pet-Ease. The formula is described for normal stress, nervousness, and hyperactivity, with storms, car rides, and fireworks among the suggested situations. Its 90-chew count may suit owners who want a multi-ingredient chew on hand, though no serving instructions appear in the supplied information, so the count alone does not establish how long a pack lasts. The tradeoff is a complex blend and no guarantee of results; it makes more sense for buyers comfortable with multiple listed ingredients than for those seeking a minimalist formula.
Pros:- Lists eight key ingredients, including L-theanine and ashwagandha
- Peanut-butter flavor offers an alternative to the duck flavor of Pet Honesty
- 90-chew count provides a clearly stated pack quantity
- Described for dogs of all sizes and a range of stress situations
Cons:- No dosage instructions are included in the supplied information
- Benefits are presented as potential support rather than guaranteed results
- The broad ingredient blend may not suit buyers seeking a simpler formula
Best for: Dog owners who prefer a chew with several named calming-support ingredients for everyday stress or occasional challenging situations.
Not ideal for: Owners who want a short ingredient list or need serving guidance to plan use for their dog’s size.
- Product type:Dog calming supplement
- Form:Chews
- Flavor:Peanut butter
- Count:90 chews
- Key ingredients:Suntheanine (L-theanine), ashwagandha, valerian root, hemp seed powder, passionflower, magnesium citrate, L-tryptophan, and ginger
- Intended use:Support for normal stress, nervousness, and hyperactivity
- Dog size:Formulated for dogs of all sizes
Our verdict“Pick Zesty Paws if you want a peanut-butter chew with a broad, named ingredient blend and can work around missing serving guidance.”
Nutri-Vet Pet-Ease Calming Chews for Dogs, 6 oz
Nutri-Vet Pet-Ease is the most travel-specific pick in this group: alongside chamomile, tryptophan, and hops for relaxation support, it includes ginger, which the product description connects with nausea and indigestion from motion sickness. That gives it a more targeted angle than Rescue Remedy Pet Calming Drops, whose description focuses on everyday stress, and a simpler named blend than Pet Honesty Dog Calming Chews. The 6-ounce pack has a hickory-smoked flavor and carries a stated NASC quality seal; it is also made in the USA. Those details may help with preference and product selection, but the supplied information gives no serving directions or evidence of results. I’d favor it for travel-prone dogs when ginger is a relevant feature, not as a proven fix for motion sickness.
Pros:- Combines chamomile, tryptophan, and hops for relaxation support
- Includes ginger, described as a potential aid for motion-related nausea and indigestion
- Hickory-smoked flavor distinguishes it from peanut-butter and duck-flavored options
- Made in the USA and carries a NASC quality seal
Cons:- No serving or dosage instructions are provided in the supplied information
- The supplied description does not provide customer review details to evaluate reported results
- The ginger-related benefit is described as support, not a guaranteed motion-sickness solution
Best for: Dog owners who want a chew for travel or other stressful events and value ginger as part of the stated formula.
Not ideal for: Buyers who need dosage instructions or expect documented evidence of effectiveness for anxiety or motion sickness.
- Product type:Soft calming chews for dogs
- Weight:6 oz
- Key ingredients:Chamomile, tryptophan, hops, and ginger
- Flavor:Hickory-smoked
- Made in:USA
- Quality seal:National Animal Supplement (NASC)
- Intended situations:Travel, storms, grooming, and boarding
Our verdict“Choose Nutri-Vet Pet-Ease if travel-related upset is part of the problem and its ginger-containing chew fits your dog.”
Rescue Remedy Pet Calming Drops, 10 mL
Rescue Remedy is the only option here described for both dogs and cats, making it a flexible choice for households with more than one species. Its liquid can be given by mouth or added to food, water, or a treat, unlike the dog-only chews from Zesty Paws and Nutri-Vet Pet-Ease. The formula is described as sedative-free, vegan, non-alcohol, and free of grain, wheat, corn, and soy. Those are practical preferences, but the central tradeoff is the evidence basis: the product uses Bach flower essences and relies on traditional homeopathic practice, which is not supported by accepted medical or scientific evidence; it is also not evaluated by the FDA. I’d treat this as a flexible-format option for buyers who accept that limitation, not as a substitute for veterinary advice or evidence-based care.
Pros:- Described for both dogs and cats
- Can be given by mouth or added to food, water, or a treat
- Sedative-free, vegan, and non-alcohol formula
- Free of grain, wheat, corn, and soy
Cons:- Bach flower essence claims rely on traditional homeopathic practices, not accepted medical or scientific evidence
- Not evaluated by the FDA
- Liquid format may be less convenient for buyers who prefer ready-to-give soft chews
Best for: Multi-pet households seeking a liquid calming product that can be administered to either dogs or cats in several ways.
Not ideal for: Owners who want a formula supported by accepted medical or scientific evidence, or who prefer a chew with named conventional ingredients.
- Volume:10 mL
- Pet types:Dogs and cats
- Administration:By mouth or added to food, water, or a treat
- Formula:Bach flower essences
- Formula attributes:Sedative-free, vegan, and non-alcohol

Pet Honesty Dog Calming Chews with Ashwagandha, Duck Flavor, 90 Count
Pet Honesty offers the broadest listed ingredient roster in this set, spanning valerian root, chamomile, hemp ingredients, passion flower, L-theanine, ashwagandha, lemon balm, L-tryptophan, magnesium citrate, and melatonin, among others. Its soft, duck-flavored format is intended for occasional stress such as travel, thunderstorms, separation, and vet visits. Compared with Zesty Paws Calming Chews, it names even more ingredients and explicitly lists a 90-count pack, but a longer roster does not by itself establish better results. The description calls the chews non-sedating while also listing melatonin, and provides no ingredient amounts or dosage details to help buyers evaluate the blend. I’d choose it for a dog that accepts soft duck-flavored chews, but lean toward a simpler formula if ingredient transparency is the priority.
Pros:- Lists a wide range of ingredients, including ashwagandha, L-theanine, chamomile, and melatonin
- Soft chew format and duck flavor may suit dogs that resist pills
- Described for stress linked to travel, thunderstorms, separation, and vet visits
- 90-chew count and 9-ounce item weight are specified
Cons:- The long ingredient list may be difficult to evaluate as a whole
- No customer review details are provided in the supplied information
- Ingredient amounts and serving instructions are not stated
Best for: Owners seeking a soft, duck-flavored chew with a broad blend of listed ingredients for a dog’s occasional stress.
Not ideal for: Owners who prefer a short ingredient list or need ingredient amounts and serving directions to assess a multi-ingredient supplement.
- Count:90 chews
- Form:Soft chews
- Flavor:Duck
- Active ingredients:Valerian root, chamomile powder, ginkgo biloba, hemp seed powder, hemp seed oil, passion flower, L-theanine, ashwagandha root, ginger root, lemon balm, L-tryptophan, magnesium citrate, and melatonin
- Intended use:Anxiety, behavior, and calming support
- Dog size:All sizes
- Item weight:9 ounces
- Stated use situations:Travel, thunderstorms, separation, and vet visits
Our verdict“Pick Pet Honesty if your dog accepts soft duck-flavored chews and you want a broad ingredient blend, but skip it if you need detailed dosing or a simpler formula.”
How We Picked
I ranked these 15 supplements by how clearly each option serves a different buyer need: everyday routine support, treat acceptance, ingredient-format flexibility, or use across more than one species. I gave more weight to clear intended use, straightforward directions, and a format that fits common feeding routines than to ingredient buzzwords alone. Chews can be simple to offer, while powders and oils may work better for pets that refuse treats or for owners who want to mix a supplement into food.
The order reflects practical differences within this lineup, not a claim that one supplement will work for every pet. Products with a distinct format or use case rise when they offer a clear choice; similar chew products are separated by their stated ingredients, flavor, and package format. I also considered limitations such as species eligibility, the need to follow label directions, and the fact that calming supplements are not a replacement for veterinary assessment of persistent, intense, or newly appearing distress.

Factors to Consider When Choosing Best Pet Calming Supplements
Before choosing a supplement, I would start with the situation you want to address and the routine your pet will actually accept. The points below help separate meaningful fit from ingredient claims that can sound similar across labels.
Match the format to your pet’s eating habits
A supplement only helps if your pet will take it consistently. Chews are convenient for dogs that see treats as a reward, but a picky eater may spit out a strong-smelling or unfamiliar chew. Powders can be mixed into food, though they are less useful when a pet leaves meals unfinished or eats separately from other animals. Oils and drops allow flexible serving, but measuring and administering liquid can take more effort. Avoid buying a large quantity before you know your pet accepts the texture and taste. If your pet takes medication or has food restrictions, ask a veterinarian whether the format or ingredients are suitable.
Choose for the trigger and timing, not a broad promise
Some buyers want support as part of an everyday routine, while others are responding to a specific event such as travel or a change at home. Those situations may call for different plans, and a supplement label may not explain how quickly an effect should appear. Check the directions for frequency and whether the product is intended for regular use or a particular occasion. Do not assume a daily formula will act like an immediate rescue treatment. Keep a simple record of the trigger, timing, and behavior so you can judge whether the routine is helping. Sudden behavior changes or distress that disrupts eating, sleep, or safety warrant a veterinary discussion.
Read the full ingredient panel instead of shopping by one ingredient
Hemp is prominent across many products in this roundup, but the word alone does not tell you how a formula differs or whether it suits your pet. Look at the complete ingredient list, serving directions, and any warnings, then check for ingredients your pet should avoid. Formulas that combine several active ingredients can appeal to some buyers, but they also make it harder to identify what your pet tolerates if a reaction occurs. A shorter list may be easier to review, though simplicity does not prove effectiveness. Do not infer a supplement’s strength from a front-label claim. If your pet has a health condition or takes other products, have a veterinarian review the label.
Check species, size, and serving directions
A product labeled for dogs should not automatically be used for cats, even when the ingredient theme sounds familiar. In this lineup, only some liquids are labeled for both dogs and cats, so confirm the intended species on the exact package. Serving instructions may also depend on weight or other factors, and a chew count is not a dosing recommendation by itself. Use the supplied directions rather than estimating from another brand’s label. Store supplements where pets and children cannot reach them, especially liquids and flavored chews. When a label is unclear, pause and ask a veterinarian or the manufacturer before giving a dose.
Decide when paying more for flexibility makes sense
A more flexible format can be worthwhile when it solves a real household problem, such as a cat sharing a home with a dog or a pet that refuses chews. If your dog happily takes treats, a straightforward chew may be easier to maintain than a liquid routine. Package size matters too: a larger supply can reduce restocking, but it is a poor value if your pet rejects the product or the directions change after veterinary advice. Compare the amount per labeled serving, not just the number of treats or milliliters in the container. Start with the smallest practical commitment when acceptance is uncertain. Spending more for extra ingredients or claims is not automatically a better fit.
Treat supplements as one part of a behavior plan
Calming supplements work best as one possible part of a broader plan, not as a stand-in for changes to the environment or professional care. A predictable routine, a quiet retreat, gradual exposure to stressful situations, and reward-based training may address needs that a supplement cannot. Avoid combining multiple calming products without guidance, since overlapping ingredients can complicate serving and monitoring. Introduce one new product at a time so you can track tolerance and behavior more clearly. If distress is severe, worsening, or linked to aggression or self-injury, contact a veterinarian rather than cycling through products. That conversation can also help identify pain or another medical issue behind the behavior.
Frequently Asked Questions
Can I give a dog calming supplement every day?
Some products are intended for regular use, while others may have different directions, so follow the exact label rather than applying one schedule to the whole category. Check serving guidance and warnings, especially if your dog takes medication or has an ongoing health condition. Introduce one supplement at a time and keep notes on behavior, appetite, and tolerance. If you are not sure whether daily use fits your dog, ask your veterinarian to review the product and routine. Do not increase a serving just because you have not noticed a change right away.
Should I choose a chew, powder, oil, or drop?
Choose the format your pet is most likely to accept consistently. A chew can be easiest for a dog that takes treats readily, while powder may suit a pet that reliably finishes food. Oil can be useful when you need a mix-in option or are shopping for a product labeled for more than one species, but accurate measuring and taste acceptance can be drawbacks. Drops may be convenient for some routines but are not automatically easier to give. If you are undecided, check whether the package gives clear species and serving directions before choosing.
Can I give a calming supplement to both my dog and cat?
Only use a product for the species listed on its label, and follow the directions for that animal. Some products in this roundup are labeled for dogs and cats, while most are specifically dog products. A shared ingredient theme does not make a dog formula safe or appropriately dosed for a cat. Cats may also have different health risks and preferences that affect the choice. Ask your veterinarian before sharing a product across pets, particularly if either animal takes medication or has a health condition.
Can I combine calming chews with another calming product?
Do not combine products just because they use different formats or brand names. Their ingredient lists may overlap, and combining them can make it harder to follow serving directions or spot what caused an unwanted reaction. Ask a veterinarian to review both labels before using them together, especially if your pet takes medication. If a professional approves a change, add one product at a time and track how your pet responds. Avoid raising the dose or adding another supplement when a product seems ineffective without first getting advice.
When should I contact a veterinarian instead of trying another supplement?
Contact a veterinarian if your pet’s distress is severe, getting worse, newly appearing, or interfering with eating, sleep, or safety. Sudden behavior changes can have medical causes, so treating them only as anxiety may delay the right care. Seek prompt help for self-injury, dangerous aggression, or other behavior that puts people or animals at risk. A veterinarian can review the supplement label, medication interactions, and whether a broader behavior plan is needed. For mild, familiar situations, a supplement may be one option, but it should not delay care when the pattern is concerning.
Conclusion
For a routine-focused dog owner who wants a format unlike the many chews, I recommend Purina Pro Plan Veterinary Supplements Calming Care as best overall; choose Greenies as best for beginners if your dog readily accepts treats. Billion Pets Hemp Oil is my best value-style pick for flexibility in a dog-and-cat household, provided the label fits both pets and your veterinarian approves its use. I would reserve best premium for buyers who have identified a specific ingredient or format preference and are willing to compare labels closely, rather than paying more for extra claims alone. For dogs that refuse chews, consider the powder or a suitable liquid; for cats, stick to products specifically labeled for cats. If your pet’s distress is persistent or intense, make a veterinary plan the priority and use supplements only as an agreed part of it.
