This article is a deep dive into fish oil supplements, their benefits and research, and also when not to feed fish oil to your dog. When it comes to nutrition, there is no one-size-fits-all approach and that needs to be taken into consideration as well.
Nutrition is essential for dogs as it supports their growth, provides energy, and promotes overall health. A balanced diet helps with digestion, maintains a healthy coat and skin, and strengthens the immune system.
I’ve been feeding fish oil to my dogs for years now and I truly recommend adding fish oil to your dog’s diet!
Understanding Fish Oil Supplements
A fish oil supplement is a dietary product that contains concentrated amounts of omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) obtained from fish. Omega-3 fatty acids are a type of essential fat that plays a crucial role in maintaining overall health.
Fish oil is typically derived from fish such as:
- salmon
- mackerel
- sardines
- trout
- pollock
- herring
- tuna
- cod
Why Fish Oil Supplements for Dogs?
This supplementation is a convenient way to increase your dog’s intake of essential omega-3 fatty acids, especially if the dog doesn’t consume enough fish in their diet.
Omega-3 fatty acids are called essential because dogs can’t produce them on their own.
Sources of Fish Oil for Dogs
There are several common sources of fish oil for dogs. These sources ensure that dogs receive the beneficial omega-3 fatty acids, EPA and DHA, which are essential for their health.
Here are the primary sources of fish oil for dogs:
- Feeding fresh fish to dogs is the perfect way to introduce fish oil into their diet. Fish such as salmon and sardines are rich sources of omega-3 fatty acids.
- Some commercial dog foods incorporate fish oil as an ingredient. These formulations are designed to provide balanced nutrition, including omega-3 fatty acids, in the daily diet of dogs. You just have to be vigilant: some dog food companies make great claims that their products contain fish oil, but in reality, the amounts are next to nothing and don’t actually benefit the dog.
- Fish oil supplements specifically formulated for dogs are readily available in the market. These supplements typically come in liquid or capsule form, making it easy to administer the appropriate dosage.
The Key Nutrients Found in Fish Oil
The specific nutrient profile of fish oil can vary depending on the type of fish used and the processing methods employed. It’s super important to choose high-quality fish oil supplements that are specifically formulated for dogs to ensure a consistent and reliable source of these nutrients!
Fish oil is a rich source of various essential nutrients, with the key ones being:
- Omega-3 Fatty Acids
- Vitamin A
- Vitamin D
- Vitamin E

Benefits of Fish Oil for Dogs’ Overall Health
Fish oil is beneficial for dogs primarily because it is a rich source of omega-3 fatty acids EPA and DHA. These omega-3 fatty acids offer a range of health benefits for dogs.
The two main types of omega-3 fatty acids found in fish oil are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids have been extensively studied and are known to provide various health benefits.
Major Benefits of Omega-3 Fatty Acids for Dogs:
- Omega-3 fatty acids play a crucial role in maintaining healthy skin and a shiny coat for dogs. They help reduce itchiness, flakiness, and dryness while promoting overall skin health.
- Omega-3 fatty acids possess natural anti-inflammatory properties, which can help dogs with conditions involving inflammation, such as allergies or inflammatory bowel disease. They help reduce inflammation throughout the body.
- Dogs, especially older ones or those with joint issues like arthritis, can benefit from the anti-inflammatory properties of omega-3 fatty acids. Fish oil helps reduce joint inflammation, alleviate pain, and improve mobility.
- Omega-3 fatty acids are vital for brain health in dogs. They support cognitive function, memory, and learning, which can be particularly beneficial for aging dogs or those undergoing training.
- Fish oil supports heart health in dogs by regulating blood pressure and reducing triglyceride levels. It can be beneficial for dogs at risk of heart disease or those with existing cardiac conditions.

How Long Does It Take to See the Effects of Fish Oil on Dogs?
The time it takes to see the effects of fish oil in dogs can vary depending on several factors, including the dog’s individual health condition and the specific benefits being targeted.
For skin and coat health, you may start to notice changes in the condition of your dog’s skin and coat within a few weeks of starting fish oil supplementation. The coat may become shinier, and the skin less dry or flaky.
In terms of joint health, it may take several weeks to a few months to observe noticeable improvements in mobility and reduced joint discomfort. Dogs with chronic joint conditions, such as arthritis, may require longer-term supplementation to experience significant benefits.
It’s important to remember that the effects of fish oil can be subtle and gradual, and individual responses may vary. It’s recommended to give fish oil supplements a fair trial for a reasonable period, which means several months.
What Are the Signs of Omega-3 Deficiency in Dogs?
Omega-3 deficiency in dogs can manifest through various signs and symptoms. Those signs may include dry, dull, or flaky skin, along with a lackluster coat.
Dogs with an omega-3 deficiency may experience increased itchiness, skin irritations, or hot spots.
Inflammatory conditions such as allergies or joint inflammation may worsen. A cognitive function might be affected, leading to decreased memory, learning difficulties, or reduced mental sharpness.
Older dogs may exhibit decreased mobility, stiffness, or discomfort in their joints.
Choosing the Right Fish Oil Supplement
When choosing a fish oil supplement for your dog, you need to first look at the Omega-3 content and additional vitamins like vitamins D & E. Check the omega-3 fatty acid content, particularly EPA and DHA levels, listed on the supplement.
A good quality fish oil supplement is nearly 100% fat, and you can easily read the Omega-3 content, milligrams and/or percentages!
Remember, fish oil supplements should complement a balanced and nutritious diet for the dog. It’s always advisable to consult with a veterinarian before introducing any new supplements or making changes to your dog’s diet.
Fish oil supplements are available as:
- liquid
- capsules
- chewable soft gels
Choose a form that is convenient for you to administer and suits your dog’s preferences. I’ve always used liquid fish oil that comes in a pump bottle.
Dosage and Administration
Follow the recommended dosage instructions provided by the manufacturer or consult with your veterinarian to determine the appropriate dosage based on your dog’s weight, health condition, and specific requirements.
Potential Risks and Side Effects
It’s advised to consult with your veterinarian before starting any new supplement, including fish oil, to ensure it is suitable for your dog’s specific needs and health condition.
Possible Adverse Effects of Fish Oil on Dogs
Please read this section before deciding to give fish oil to your dog. Even though I have listed so many amazing benefits of feeding fish oil, it’s not for every dog. There are a few reasons and I will go them through with you below:
Heartburn
Fish oil can sometimes cause gastrointestinal issues in dogs. Dogs with sensitive stomachs can experience heartburn more easily, so adhere to the recommended dosage provided by the supplement manufacturer or as advised by your healthcare professional.
Consuming oil supplements along with a meal or snack can help prevent stomach irritation and aid in digestion.
Allergic Reactions
In rare cases, dogs may have an allergic reaction to fish oil. In theory, a well-made fish oil product contains only pure fat and doesn’t contain any fish protein, the actual cause of allergies.
Signs of an allergic reaction can include itching, swelling, hives, difficulty breathing, or other signs of distress. If you observe any of these symptoms, discontinue use and seek veterinary assistance immediately.
In these cases, instead of fish oil, you can consider a plant oil supplement.
Potential Interactions with Medications
Fish oil supplements can interact with certain medications, such as anticoagulants (blood thinners). If your dog is on any medication, it’s crucial to consult with your veterinarian before adding fish oil to their regimen to ensure there are no potential interactions.
Evaluating the Quality and Purity of Fish Oil Products
Opt for high-quality fish oil supplements that are specifically formulated for dogs. Look for products that come from reputable sources and undergo proper purification processes to remove contaminants. Unfortunately, the fish used to produce fish oil can contain traces of heavy metals, such as mercury or lead.
Storage and Shelf Life
Poorly stored or expired fish oil supplements can become oxidized and rancid. Consuming rancid oil can lead to gastrointestinal upset and potentially worsen inflammation.
It is important to store fish oil properly and check the expiration date to ensure freshness. Some supplements need to be stored in the refrigerator. Store fish oil supplements in a cool, dark place to prevent oxidation.
Sustainability And Ethicalness of Fish Oil
If you read more articles about fish oil supplements, and the title says why you should avoid these supplements, the articles are probably going to take this angle.
And it is a real problem to be aware of. The fish oil industry faces sustainability and ethical concerns constantly.
One significant concern is overfishing, which occurs when fish are caught at a rate faster than they can reproduce. This can lead to a decline in fish populations and disrupt the delicate balance of marine ecosystems.
Overfishing not only jeopardizes the long-term availability of fish as a resource but also has ripple effects on other species dependent on them for food and habitat.
Certain fishing methods, such as trawling, can cause damage to the ocean floor and unintentional bycatch of non-targeted species.
Poor fishing practices can also lead to unsustainable practices in the industry, compromising the long-term availability of fish and impacting the livelihoods of local fishing communities.
Are There Any Alternatives to Fish Oil for Dogs?
Once I’ve written in-depth articles about plant oils and krill oil, I’ll link them here!
While fish oil is a common and effective source of omega-3 fatty acids for dogs, there are alternatives available, such as plant oils and krill oil.
Plant oils, such as flaxseed oil and hempseed oil, can be used as substitutes for fish oil. They contain alpha-linolenic acid (ALA), which can be converted into EPA and DHA by the dog’s body to a limited extent.
Dogs have a less efficient ability to convert ALA, and the conversion rates may vary among individuals. Therefore, plant oils may not provide the same levels of EPA and DHA as fish oil.
Krill oil is another alternative to fish oil for dogs. It is derived from tiny shrimp-like crustaceans called krill. Krill oil contains EPA and DHA in a different molecular form, known as phospholipids, which some claim is more easily absorbed by the body compared to the triglyceride form found in fish oil.
Krill oil also contains astaxanthin, a powerful antioxidant. However, the research comparing the benefits and absorption rates of krill oil versus fish oil in dogs is limited, and more studies are needed to draw definitive conclusions.
Conclusion
Fish oil supplements offer a myriad of benefits for dogs, making them a valuable addition to their diet. The rich source of omega-3 fatty acids, EPA and DHA, in fish oil supports various aspects of a dog’s health, including joint function, skin and coat health, immune system support, and cognitive function.
When selecting a fish oil supplement for your dog, it’s essential to choose a high-quality product that is free from contaminants and meets the necessary standards. Consult with your veterinarian to determine the appropriate dosage based on your dog’s specific needs and health conditions.
By incorporating fish oil supplements into your dog’s routine, you can help alleviate joint pain and inflammation, promoting mobility and comfort. The omega-3 fatty acids contribute to a healthy and lustrous coat while reducing skin irritations and allergies. The immune system receives a boost, enhancing your dog’s ability to fight off infections and diseases. Fish oil supports cognitive health, improving memory and mental acuity.
