Benefits Of Salmon Oil For Dogs

When looking for the best salmon oil for your pup, you want to ensure it contains both eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the most beneficial omega-3 fatty acids. So, what does salmon oil do for dogs? Fish oil for dogs and cats has been studied more than most types of pet supplements. Here are a few of the many health benefits for dogs.

  • Skin allergies: moisturizes the skin and reduces inflammation and itchiness.
  • Decreases shedding & improves coat health.
  • Supports immune and brain health and may improve cognitive function.
  • Joint problems and injuries: reduces inflammation and pain and improves mobility.
  • Lowers blood pressure.
  • May decrease the risk of certain cancers.
  • Heart disease: vets often recommend omega-3 fatty acids for dogs with congestive heart failure and to protect against irregular heartbeats (arrhythmia).
  • Slows the progression of chronic kidney disease.

Another benefit of salmon oil is that it helps balance out omega-6 fatty acids in their diet. While dogs need some omega-6, many commercial dog foods, especially those containing a lot of grains, corn-fed meat, or refined oils, contain too much omega-6. And excessive amounts of omega-6 fatty acids can cause chronic inflammation. But giving your pup salmon oil can solve this problem.

Is Salmon Oil Safe For Dogs?

Understandably, many pet owners are concerned about harmful levels of mercury and other heavy metals and toxins in fish oil. And this is a definite problem with some low-quality oils because the FDA doesn’t regulate pet supplements.

Therefore, it’s extremely important to choose a salmon oil from a manufacturer who has their products independently tested for purity. Also, look for pet supplements with the National Animal Supplement Council (NASC) Quality Seal, which is given to brands that meet this organization’s strict quality requirements.

Our Personal Experience With Salmon Oil For Dogs

I work at a health food store that also sells supplements for pets. Fish oil, particularly salmon oil, is a popular choice for dog parents who want to improve their pet’s overall health. 

Fish oil supports a dog’s heart, joints, eyes, skin, coat, and more. Salmon oil also naturally contains a carotenoid called astaxanthin, which is an antioxidant that boosts immune function and protects from cellular damage.

I love that people are focusing on their pet’s well-being, but I always emphasize that quality is everything when it comes to fish oils. Poor-quality salmon oil can do more damage than not supplementing at all.

When shopping for fish oil, focus on freshness, purity, and sourcing. Fresh fish oil reduces the risk of free radical formation. Aside from the fishy taste and smell, ingesting rancid oils may create oxidative stress, thus damaging healthy cells and creating inflammation. 

The second factor is purity. Quality companies exceed standards for the allowance of heavy metals and toxic chemicals in their product. Pollutants like dioxins and PCBs can cause a number of health issues, including liver problems and skin conditions. Check to ensure the brand uses third-party testing to ensure purity. 

Finally, you want to consider where the product is sourced. Generally, wild-caught fish tend to deliver a better nutrient profile than farm-raised fish. Just make sure the fish are sustainably sourced to minimize harmful environmental impacts.

How Much Salmon Oil Should I Give My Dog?

How much salmon oil for dogs per day depends on several factors, including your pup’s weight, the brand of oil (i.e., the levels of omegas, EPA, and DHA), the presence of health conditions, and more. It also depends on your pup’s diet because some dog foods already have omega-3 fatty acids in them. So, check the list of ingredients in your dog food. If it contains salmon or fish or is fortified with omega-3s, you should consult your veterinarian to determine how much salmon oil to give your pup as a supplement. Too much fish oil can cause side effects.

Even if your pup’s food doesn’t contain omega-3 fatty acids, it’s a good idea to get the okay from your vet before giving your dog any type of supplement. You should be fine as long as you follow your product’s dosage recommendations unless your vet has other guidance.

What Are The Risk Factors & Side Effects Of Salmon Oil For Dogs?

Fish oil is relatively safe, but some conditions could present risks, including dogs with bleeding disorders, diabetes, a history of pancreatitis, and diarrhea. For these dogs, it’s important to discuss fish oil supplementation with your vet.

In healthy dogs, fish oil is considered very safe. Potential side effects, which typically occur with doses that are too high, include vomiting, diarrhea, slow wound healing, an oily coat, and fishy breath. Also, if your dog is on a grain-based diet, taking salmon oil daily over a long period may cause a vitamin E deficiency. Check with your vet to see if you should be giving your pup a vitamin E supplement as well.

Frequently Asked Questions

Here are some additional questions we see frequently from our readers about salmon oil. Don’t see yours here? Ask us in our comments.

Salmon Oil vs Fish Oil For Dogs: What’s The Difference?

Both oils are excellent sources of omega-3 fatty acids, but salmon oil usually has higher levels and is better absorbed by the body. Products labeled “fish oil” or “omega-3” contain oil extracted from multiple wild-caught fish (e.g., herring, pollock, etc.), and it may or may not contain salmon. Typically, salmon-free fish oil has less of a fishy odor and taste than salmon oil. See our reviews of the best fish oil for dogs if you’d prefer an odorless option.

What Does Salmon Oil Do For Dogs With Joint Pain?

Salmon oil is a powerhouse supplement for aching pups because it contains the omega-3 fatty acids EPA and DHA, which reduce the inflammation associated with joint pain from such conditions as arthritis and hip dysplasia. Dogs can’t make their own omega-3 fatty acids, so it’s an important part of their diet.

Is Salmon Oil Good For Dogs’ Itchy Skin?

Many pup owners find a lot of success with a daily salmon oil supplement to relieve their dog’s itchy skin. DHA and EPA found in salmon oil help reduce skin inflammation and itchiness. These omega-3s also moisturize the skin, which helps protect it from allergens such as dust, pollen, etc.

Is Salmon Oil For Humans Safe For Dogs?

Pure salmon oil (without any other ingredients) that’s made for human consumption could be safe for your pup. But you should consult your vet to ensure the product you’re considering is okay. Your vet can also determine the safe dosage.
