Dr. Dodd’s is one of the best, but did you get the list of what is actually tested for? It isn’t comprehensive, in fact, it’s rather limited. There could easily be things that your dog is sensitive to that are not tested for and things that your dog would be just fine on, but weren’t tested for. Get the full list so you can compare it to the ingredient list for the food that you are feeding or food that you are thinking about feeding. That way you will know which ingredients were tested for and which weren’t.
Salmon oil should not be a problem because the protein is removed, however there are no guarantees in life, so it might be better if you went with krill oil, calamari oil, anchovy or sardine oil, or even marine algae oil. You could even try adding a little coconut oil to his diet in addition to the omega 3 oil, about 1/2 teaspoon.
