Yes it is

I tend to rotate between cod liver and salmon. Cod liver is GREAT for pups, but can be overdone (it has very high Vitamin A & D content, which are cumulative fat-soluble vitamins).

Salmon Oil doesn't have much in the way of vitamins, but it does have a ton of Omega-3 fatty acids ... which play a crucial role in brain function, as well as normal growth and development ... and also reduce inflammation and may help lower risk of chronic diseases such as heart disease, cancer, and arthritis.
