Yes. But with some reservation. Cod liver oil contains Omega 3 fatty acids, which have anti-inflammatory properties. (Decreasing inflammation in the body allows for greater immune system efficiency overall.) Cod liver oil can boost health in several areas: the cardiovascular system, brain, joints, skin, and fur. When you consider that many processed dog foods lack the essential Omega 3 fatty acids dogs need, cod liver oil seems like a great supplement. However, some recommend using fish oil instead of cod liver oil because the latter contains vitamins A and D. These are both good vitamins, of course. But if your dog already has sufficient vitamin A and D levels, the excess gets stored in the body and causes the liver to work harder than it needs to processing the surplus.
Check with your veterinarian about whether cod liver oil is right for your dog. If so, add a spoonful to your dog’s food occasionally—maybe once a week, rather than daily. Or follow your vet’s recommended dosage.
