Does my dog's fish oil need Omega 3 and Omega 6 for best health?

Updated On September 23rd, 2025

My vet said I should give fish oil that also has omega 6 in it. I've just been giving straight fish oil. Are omega 3s plus omega 6s better than just omega 3s? Why? Thanks!

If you are feeding a quality diet, it is likely your pet is receiving sufficient quantities of Omega 6s. Omega 3s break down quicker when exposed to light and air, so it is difficult to maintain therapeutic levels in commercial foods. The two best Omega 3s for dogs are DHA and EPA. Fish oil may contain high levels of both however, it may also contain more toxins. Oil from fish livers may also contain dangerous amounts of vitamins A and D.
