When it comes to supporting your dog’s health, omega3 fish oil is a popular supplement known for promoting a shiny coat, healthy skin, and joint comfort. The best options vary from high-concentration capsules to liquid formulas that are easy to dose. Nordic Naturals Omega-3 Pet stands out as the overall top pick for its purity and balanced EPA and DHA content, while Zesty Paws Wild Alaskan Oil offers great value with a versatile blend. However, choosing the right product involves tradeoffs: higher concentration often means higher cost, and liquid oils may be messier to administer. Continue reading for a detailed comparison to help you find the best omega3 fish oil for your dog’s specific needs.

- Products with added support for skin, coat, and joints tend to include specific EPA/DHA ratios tailored to those needs.

More Details on Our Top Picks
Nordic Naturals Omega-3 Pet, Unflavored – 180 Soft Gels, 320 mg Omega-3 per Soft Gel
This supplement stands out for its focus on purity and targeted benefits, making it an excellent choice for pet owners who prioritize high-quality ingredients. Unlike liquids such as Zesty Paws Wild Alaskan Blend, these soft gels eliminate mess and are less likely to cause a spill, but the soft gel format can be difficult for some dogs to swallow, especially smaller breeds. The wild-caught, non-GMO fish oil ensures superior absorption and fewer artificial additives compared to lower-grade options, translating into more consistent health benefits. However, its exclusive focus on dogs means it isn’t suitable for multi-pet households with cats or other animals. Overall, this pick is ideal for owners seeking a premium, straightforward omega-3 supplement that supports heart, skin, coat, and immune health.
Pros:- Supports heart, skin, coat, and immune health effectively
- Made from wild-caught, non-GMO fish oil ensuring high quality
- No artificial additives, gluten, or dairy
Cons:- Soft gels may be hard for some pets to swallow
- Only suitable for dogs, not versatile for multi-pet households
Best for: Dog owners who want a premium, easy-to-absorb omega-3 supplement with minimal fuss
Not ideal for: Pet owners with extremely small or picky dogs who dislike soft gels or have difficulty swallowing pills
- Quantity:180 soft gels
- Omega-3 per soft gel:320 mg

Zesty Paws Wild Alaskan Omega-3 Blend Pollock + Salmon Oil for Dogs and Cats – Skin and Coat Support, 16oz
This liquid supplement excels in versatility, making it ideal for households with both dogs and cats, especially since it can be added directly to food. Compared to capsule-based options like Nordic Naturals, its liquid form offers simplicity but can be messy if not carefully handled, especially with active pets. Made from high-quality Alaskan salmon, it provides a rich source of omega-3s that promote shiny coats and healthy skin, similar to the benefits of Omega 3 Fish Oil for Dogs and Cats but with added convenience as a food topper. However, the liquid format may not appeal to all pets, and regular dosing is necessary to see consistent results. This product is perfect for owners who want a flexible, trusted source of omega-3s for multiple pets.
Pros:- Supports healthy skin, coat, and immune system
- Easy to serve as a food topper, reducing fuss
- Made from premium Alaskan salmon with NASC certification
Cons:- Liquid formula may be messy or difficult to portion accurately

Our verdict“Ideal for multi-pet households that prefer a flexible, easy-to-use omega-3 source for consistent skin and coat health.”
Omega 3 Fish Oil for Dogs and Cats – Liquid Fish Oil for Skin and Coat Support
This liquid fish oil offers a comprehensive approach to pet health, combining wild-caught pollock and cod liver oil for a broad spectrum of omega fatty acids. Compared with capsule-based options like Pure Omega 3 Fish Oil, its easy-to-add liquid form makes daily dosing straightforward, especially if mixed into meals. It supports not only skin and coat but also joint, immune, brain, and heart health, making it a versatile choice for holistic pet wellness. However, the unflavored profile might be less appealing for picky eaters, and daily administration is essential to maintain benefits. This product is well-suited for owners who want a multi-functional supplement that can be easily integrated into regular feeding routines.
Pros:- Supports coat, skin, joints, immune, and heart health
- Made from sustainably sourced wild fish
- Easy to add to meals without capsules or tablets
Cons:- Unflavored may be less palatable for some pets

Omega 3 for Dogs – 250 Fish Oil Chews for Skin, Coat, and Joint Support
This chew-based omega-3 supplement combines the benefits of fish oil with added probiotics, making it particularly appealing for dogs who prefer treats over liquids or capsules. Its formulation promotes shiny coats and reduces shedding, similar to Zesty Paws’ liquid offerings, but in a more convenient, mess-free format. The inclusion of probiotics supports digestive health, adding extra value. However, large chews may be unsuitable for small dogs or those with chewing difficulties, and some dogs with fish allergies might need to avoid it. This option suits owners who want a tasty, all-in-one supplement that supports skin, coat, and joint health in a hassle-free form.
Pros:- Promotes healthy skin, coat, and reduces shedding
- Supports joint and heart health
- Includes probiotics for digestive support
Cons:- Large chews may be difficult for small dogs
- Potential fish allergy concerns for sensitive pets

- Supports:Skin & Coat, Joint, Heart, Immune health
Our verdict“A tasty, convenient option for dog owners who prefer chew treats that deliver skin, coat, and joint benefits.”
Pure Omega 3 Fish Oil for Dogs – Wild Caught from Iceland, 1000mg, 180 Capsules
This high-dose capsule option is tailored for owners of larger or active dogs who need consistent, potent omega-3 supplementation. Its wild-caught Icelandic fish source ensures high quality and sustainability, similar to Nordic Naturals but with a focus on higher omega-3 per capsule. The low-odor capsules are a plus for owners tired of fishy smells, but some small or picky dogs may find capsules difficult to take, especially without treats or mixing. This product is most effective when used as part of a long-term health plan for joint, skin, and brain support, but individual dogs’ sensitivities to fish oil should be considered. It’s best suited for owners committed to daily dosing and larger breeds.
Pros:- Provides a high dose of omega-3 fatty acids per capsule
- Made from wild-caught Icelandic fish ensuring quality and sustainability
- Low odor, easy to administer with no fishy smell
Cons:- Capsules may be difficult for small or picky dogs to swallow
- Some dogs might be sensitive to fish oil supplements individually
Best for: Owners of large or active dogs needing a concentrated omega-3 supplement for joint, skin, and brain health
Not ideal for: Small or sensitive dogs that dislike capsules or are prone to fish allergies
- Flavor:Wild Caught Sardines, Herring, Mackerel & Anchovy
- Item Form:Soft Gel
- Active Ingredients:Wild Caught Fish From Iceland
- Item Weight:3 Grams
- Amount per Capsule:300mg Omega 3 fatty acids
Our verdict“Best for owners of larger dogs seeking a potent, long-term omega-3 supplement with minimal odor.”
Omega 3 Fish Oil for Dogs – Supports Skin, Coat, Joints, Brain, and Heart Health
This liquid supplement stands out for its high-quality, sustainably sourced fish oils from wild-caught anchovies, herring, mackerel, and sardines. Unlike some options such as Nordic Naturals Omega-3 Pet, which are tailored for large breed dogs, this formula is suitable for all sizes. Its molecularly distilled, toxin-free process offers peace of mind, making it ideal for owners prioritizing safety. However, the need to squirt onto food daily may be less convenient compared to pump-based options like Natural Dog Company Wild Alaskan Salmon Oil. While it supports skin, coat, joints, and vital organ health, dogs with fish allergies should skip it. Overall, this pick makes the most sense for pet owners seeking a versatile, safe, and high-quality fish oil supplement for daily use.
Pros:- Supports skin, coat, joints, brain, and heart health
- Made from sustainably sourced wild fish, human-grade quality
- Molecularly distilled to remove toxins, ensuring safety
Cons:- Requires daily squirting onto food, which can be inconvenient
- Not suitable for dogs with fish allergies
Best for: Owners of dogs of all breeds and ages who want a safe, multi-benefit supplement with minimal fuss.
Not ideal for: Dog owners with fish allergies or those preferring pre-portioned capsules or pumps for ease of use.
- Source:Wild-caught fish (Anchovies, Herring, Mackerel, Sardines)
- Form:Liquid
- Ingredients:Omega-3 DHA and EPA
- Safety:Molecularly distilled, toxin-free
- Suitable For:All breeds and ages
Our verdict“This liquid fish oil provides a safe, versatile, and high-quality daily supplement ideal for owners seeking comprehensive health support.”
Fish Oil for Dogs, Salmon and Pollock Liquid Omega 3, 64 oz
Compared with the more comprehensive Omega 3 Fish Oil for Dogs, this 64 oz bottle offers a larger quantity at a more affordable price, making it better suited for owners with multiple dogs or who prefer less frequent refills. Its blend of salmon and pollock oils emphasizes skin, coat, and immune health, but the liquid form may be messier to administer than pump-based options like Natural Dog Company Wild Alaskan Salmon Oil. While it supports healthy shedding and overall wellness, consistent daily use is necessary to see benefits. It’s ideal for owners seeking a cost-effective, large-volume solution but less convenient for those who dislike handling liquids or prefer pre-measured doses. This product is best for budget-conscious owners who want to support their dog’s coat and immunity reliably.
Pros:- Supports healthy skin, shiny coat, and immune system
- Large 64 oz volume offers great value
- Sustainable sourcing from wild salmon and pollock
Cons:- Liquid form may be messy and less convenient

Best for: Owners of multiple dogs or those looking for a cost-effective, large-volume omega-3 supplement for skin and immune support.

- Active Ingredients:Pollock Oil, Salmon Oil
- Product Benefits:Digestive Health, Heart, Immune, Joint, Skin
- Dog Breed Size:All
- Item Weight:4.1 Pounds

Our verdict“This large-volume fish oil is ideal for budget-conscious owners who prioritize skin and immune health but don’t mind handling liquids regularly.”
Nutramax Welactin Omega 3 Fish Oil for Dogs, 16 Ounce Liquid
This formula makes the list for its veterinarian backing and broad health support, including skin, coat, joints, immune, kidney, and brain health. Compared to smaller bottles like Nordic Naturals Omega-3 Pet, this 16 oz size balances ease of use with comprehensive benefits. Its high-quality EPA and DHA provide targeted support, but measuring and pouring into food can be less convenient than pump or capsule options. Suitable for dogs of all sizes and life stages, it’s an excellent choice for owners valuing science-backed products recommended by professionals. However, the necessity of manual measurement may deter those seeking quick, no-fuss solutions. Overall, it’s a reliable, vet-approved supplement for holistic wellness management.
Pros:- Supports skin, coat, joint, immune, kidney, and brain health
- Backed by veterinary recommendation and scientific quality standards
- Easy to administer with included scoop
Cons:- Requires measuring and pouring, less convenient than capsules or pumps

Natural Dog Company Wild Alaskan Salmon Oil for Dogs – Omega 3 Fish Oil Supplement with EPA & DHA, 16 oz
This oil provides a straightforward way to boost your dog’s daily nutrition, especially if you prefer food toppers over liquid drips or capsules. Its wild Alaskan salmon and pollock oils emphasize healthy skin, shiny coat, and joint mobility, similar to the benefits from Omega 3 Fish Oil for Dogs. Dosing is simple—just pumps based on weight—which is more convenient than measuring liquids but less flexible than capsules. Made from responsibly sourced wild Alaskan fish, it appeals to owners who prioritize sustainability.

Overall, it suits owners seeking an easy, natural addition to their dog’s food for seasonal comfort and coat health.
Pros:- Supports healthy skin, coat, and seasonal comfort
- Easy to dose with a pump for simple application
- Made from responsibly sourced wild Alaskan fish

Nordic Naturals Omega-3 Pet, Unflavored, 16 oz
This product is tailored specifically for large to very large dogs, offering a potent 1380 mg of omega-3 per teaspoon. Compared to Omega 3 Fish Oil for Dogs, which has a broader appeal, this formula’s triglyceride form ensures better absorption, especially important for larger breeds needing higher doses. While it delivers high purity from wild-caught fish, the liquid form might be less convenient for owners who prefer capsules or pre-measured doses. The unflavored profile makes it easier to mix into food without altering taste, but the liquid’s handling may be a drawback for some. It’s best suited for owners of big dogs who need an effective, high-dose supplement with optimal absorption.
Pros:- High omega-3 content per teaspoon for large dogs
- Supports heart, skin, coat, and immune health
- Triglyceride form for better absorption

This blend from Zesty Paws stands out for its versatility, supporting both skin, coat, immune function, and general health in dogs and cats, making it ideal for multi-pet households. Compared with the Nordic Naturals Omega-3 Pet, this option offers a broader benefit profile, though it may require consistent use for visible results and can be messy due to its oil form. Its EPA and DHA content from wild Alaskan salmon and pollock oils deliver meaningful health benefits, especially for pets with skin issues or dull coats. However, some pet owners might find the oil consistency inconvenient to measure or handle daily.
Pros:- Supports healthy skin and shiny coat
- Easy to add to food for convenience
- Rich in EPA and DHA for broad health benefits
Cons:- Requires regular application for noticeable results
- Oil form may be messy and inconvenient for some owners

Salmon Oil for Dogs – Omega 3 Supplement for Skin & Coat – 8 oz Liquid
Chew + Heal’s Norwegian salmon oil offers a flavorful, liquid omega-3 supplement that many dogs find appealing, making it an excellent choice for owners who want a tastier way to support skin and coat health. Compared with the Nordic Naturals Omega-3 Pet, this product is designed for easy mixing into meals, though its fish oil scent and liquid form require careful measurement to avoid overfeeding. It effectively soothes itchy or dry skin and promotes a shiny coat, but the liquid format may be less convenient for owners who prefer capsules or powders. Fish oil sensitivity or allergies could also limit its use for some pets.
Pros:- Supports healthy skin and shiny coat
- Helps soothe itchy, dry skin
- Easy to incorporate into meals
Cons:- Liquid form requires careful measurement
- Fish oil scent may be off-putting for some pets

Nordic Naturals Omega-3 Pet, Unflavored – 8 oz
Nordic Naturals’ unflavored fish oil is formulated specifically for medium and large dogs, emphasizing high absorption triglyceride form that maximizes omega-3 benefits. Compared with the salmon oil from Chew + Heal, this product offers a neutral flavor, making it suitable for sensitive pets, although the liquid form may be less convenient than capsules. Its non-GMO, wild-caught fish source ensures quality and purity, supporting heart, skin, coat, and immune health effectively. However, the smaller size and liquid format might make daily dosing less straightforward for owners who favor capsules or pre-measured servings.
Pros:- Supports heart, skin, coat, and immune health
- Made from wild-caught, non-GMO fish
- High absorption triglyceride form
Cons:- Only suitable for dogs, not cats

Pet Protect M/L Dog Omega-3 Supplement, Supports Inflammatory Response, 60 Count
Pet Protect’s capsules and liquid options are designed to target inflammation and support overall health, making them ideal for dogs with joint issues or inflammatory conditions. Compared to the liquid fish oils from Nordic Naturals or Chew + Heal, these capsules offer a convenient, mess-free alternative, but require capsule snipping or careful liquid dosing, which some owners may find cumbersome. The molecular distillation process improves absorption, and the EPA and DHA from anchovy oil support joint, brain, and immune functions effectively. This product is tailored for medium and large dogs with specific health concerns, but its limited size and lack of flavor details might be a drawback for some pet owners.
Pros:- Supports multiple health areas including joints and immune system
- Highly absorbable EPA and DHA
- Available in capsules or liquid for convenience
Cons:- Requires capsule snipping or careful measurement of liquid
- No flavor options or taste considerations provided

Not ideal for: Pet owners with small dogs or those seeking a flavor-enhanced or pre-measured supplement.
- Size:60 Count
- Supports:Inflammatory response, joint, eye, brain, heart, kidney, immune health
- Source:Anchovy oil
- Distillation:Molecular distillation
Our verdict“This supplement is well-suited for owners seeking a concentrated, targeted omega-3 solution for joint and inflammatory health in medium or large dogs.”
Zesty Paws Wild Alaskan Omega-3 Blend Pollock + Salmon Oil for Dogs and Cats – Skin and Coat Support, Omega 3 Supplement for Pets, 32oz
This larger 32oz bottle from Zesty Paws offers a cost-effective option for pet owners who want to provide omega-3 support over the long term or to multiple pets. It supports healthy skin, shiny coats, and overall health, similar to the smaller 8.5oz version but at a more economical per-ounce price. While its EPA and DHA content remains consistent, the larger size can be messier and requires more storage space. Some pets may also resist the fish oil flavor, and owners need to be diligent about regular dosing to see benefits. Compared with the 8.5oz bottle, this is better for those with high usage needs or multiple animals, though less convenient for occasional use.
Pros:- Supports healthy skin and shiny coat
- Cost-effective for long-term use
- Rich in EPA and DHA for overall health
Cons:- Requires regular handling of oil, which can be messy
- Taste may not appeal to all pets
Best for: Owners with multiple dogs or those wanting a bulk supply for long-term use on a budget.

- Item Weight:32 Ounces

How We Picked
To determine the best omega3 fish oil options for dogs, I evaluated each product based on purity, sourcing quality, concentration of EPA and DHA, ease of use, and overall value. We prioritized products with transparent ingredient lists and reputable manufacturing standards. Convenience factors, such as liquid versus capsule form, were also considered because they impact daily use and compliance. Price per serving was a key metric, but so was the balance of EPA and DHA, which directly influences health benefits. The ranking reflects a mix of quality, usability, and cost-effectiveness, aiming to recommend options for a broad range of dog owners and needs.Factors to Consider When Choosing Omega3 Fish Oil Dogs
Choosing the right omega3 fish oil for your dog involves understanding several key factors. While all products aim to support skin, coat, and joint health, differences in sourcing, concentration, and form can significantly impact effectiveness and ease of use. Making an informed decision helps maximize benefits without overspending or ending up with a product that doesn’t suit your pet’s specific health needs. Here are the main considerations to keep in mind.Concentration and EPA/DHA Ratios
Pay attention to the concentration of omega3 fatty acids, especially EPA and DHA, as these are the active components that deliver health benefits. Higher EPA levels tend to support inflammation reduction and joint health, while DHA is important for brain and eye development. Products vary widely in these ratios, so consider your dog’s specific needs—whether it’s joint support, skin health, or cognitive function. Higher concentrations mean fewer doses needed, but they often come at a higher price.
Source and Purity
The quality of the fish oil hinges on its sourcing and processing. Wild-caught, sustainably sourced oils from cold waters like Alaska or Iceland generally offer purer, fresher oil with higher EPA and DHA levels. Look for products that are tested for contaminants such as heavy metals and PCBs, which can compromise safety. Transparent labels and third-party testing are signals of higher quality, ensuring you’re giving your dog a safe supplement.
Form: Liquid vs. Capsules
Liquid fish oils are often easier to administer for larger or multiple dogs, as they can be mixed directly into food. Capsules, on the other hand, are more convenient for travel and portion control but may require breaking open or using a pill pocket. Consider your dog’s preferences and ease of administration—some pets resist capsules, making liquids a better choice for consistent dosing.
Cost and Value
Price per serving varies significantly, and larger bottles often provide better long-term value. However, higher concentration and purity products tend to cost more upfront. Balance your budget against your dog’s health goals—if your dog has specific needs like skin allergies or joint issues, investing in a higher-quality, concentrated supplement might be more cost-effective in the long run. Don’t forget to factor in how often you’ll need to replace the bottle.
Additional Benefits and Ingredients
Some omega3 supplements include added ingredients such as antioxidants, vitamin E, or other fatty acids to enhance health benefits. Check if the product supports specific concerns like inflammation, skin health, or cognitive function. However, be cautious of unnecessary additives or fillers that don’t contribute to your dog’s health and could increase costs without added value.
Frequently Asked Questions
How much omega3 fish oil should I give my dog daily?
The appropriate dosage depends on your dog’s weight, age, and health status. Most products provide recommended serving sizes on the label, typically ranging from 50 to 300 mg of EPA and DHA per 10 pounds of body weight. It’s best to follow these guidelines or consult your veterinarian for personalized advice, especially if your dog has underlying health conditions or is on medication.
Can omega3 fish oil help with my dog’s itchy skin and allergies?
Yes, omega3 fish oil is known for its anti-inflammatory properties and can help reduce skin irritation and allergic reactions. Consistent supplementation over several weeks is usually needed to see noticeable improvements. Look for products with higher EPA levels, as this fatty acid is particularly effective at calming skin inflammation. Always check with your vet before starting a new supplement for allergy concerns.
Are liquid fish oils or capsules better for my dog?
Liquid fish oils tend to be easier to mix into food, especially for dogs that resist swallowing pills. They also allow for more flexible dosing and easier adjustments. Capsules might be more convenient for travel or for owners who prefer pre-measured doses, but some dogs may resist swallowing them. Your choice should consider your dog’s preferences and your ease of administration.
Is wild-caught fish oil always better than farmed options?
Wild-caught fish oils generally offer higher purity, better EPA/DHA ratios, and fewer contaminants compared to farmed options. They also tend to be more sustainably sourced. However, they can be more expensive. When choosing, prioritize products that specify wild-caught origins and have third-party testing to ensure safety and quality.
Should I choose a flavored or unflavored omega3 fish oil for my dog?
Most dog-specific omega3 oils are unflavored or naturally flavored to minimize taste issues. Flavored options may help dogs accept the supplement more easily, but check the ingredients to avoid artificial additives. If your dog is particularly sensitive or refuses unflavored oils, a flavored version could improve compliance. Always select products with minimal unnecessary ingredients for best health benefits.
