How to Choose the Best Fish Oil Supplement for Dogs and Cats
June 16, 2026Why Consider Fish Oil Supplements for Pets?
Fish oil supplements are valued for their high omega-3 content. This nutrient is essential for supporting your pet's health. Omega-3 fatty acids, specifically EPA and DHA, support a healthy coat and skin, a healthy immune system, and heart function.
A smooth, shiny coat is often a sign of a healthy pet, and fish oil provides the omega-3s that support that. Consider adding fish oil to your pet's routine for several reasons:
-
Supports healthy skin and a glossy coat
-
Helps maintain normal shedding
-
Helps support heart function
-
Supports a healthy immune system
Key Benefits of Fish Oil for Dogs and Cats

Understanding Omega-3s: What to Look For
Omega-3 fatty acids are the foundation of fish oil supplements. They consist mainly of EPA and DHA, which are important nutrients for your pet. Understanding these components helps you choose the right supplement.
When selecting fish oil, quality matters. Look for oils sourced from fish like sardines, anchovies, or salmon. These smaller fish tend to have lower levels of contaminants such as mercury.
Beyond the source, check for third-party testing and certifications, which confirm the supplement's purity and potency. Here's what to look for:
-
High EPA and DHA levels
-
Source fish types
-
Third-party testing certification
Choosing a well-reviewed, third-party tested product adds an extra layer of confidence for your pet's health.

Choosing the Right Fish Oil Supplement for Pets
When choosing a fish oil supplement for your pet, the most important factors are sourcing, form, and third-party verification. Not all fish oils are the same, and the difference in quality can directly impact how much your pet benefits.
Look for a product that uses high-quality fish sources, as this affects the overall omega-3 content compared to generic blends. The oil should also be in triglyceride form, which is more bioavailable than ethyl ester, so your pet's body can absorb and use it more efficiently.
Vital Pet Life Fish Oil checks all of these boxes. It is in triglyceride form, MSC-certified for sustainable fishing, and verified by Orivo's NMR lab testing for species and geographic origin, so you know exactly what is in the bottle.
Here's a quick checklist when evaluating any fish oil supplement:
-
High-quality fish sourcing
-
Triglyceride form for better absorption
-
Third-party tested for purity and potency
-
MSC or sustainability certification
-
No additives or preservatives

Drizzle over your pet's regular food since most pets love the taste
-
Store in a cool, dark place and refrigerate after opening to prevent oxidation

Consult your vet if your pet is on medication, especially blood thinners, as omega-3s may affect normal clotting processes
Consulting your veterinarian is always a good idea, especially if your pet has existing health conditions. They can provide specific guidance based on your pet's individual needs.
