i'm not so sure about the salmon, only because he won't eat the tuna, and when he does take a little lick he gets a cross look on his face ha ha. we tried a little duck, with no luck. he won't eat potatoes, not even ones with something on it to make it yummy. here's what we've tried.
pork, beef, tuna, gravy, the gravy for dog food, bullion, beef stock from cooking, various bird meats (turkey, duck, chicken), we tried yogurt after i read a post, but he barfed. we've tried potatoes and other veggies, eggs, vanilla wafers, i even mixed a few pieces of cat food thinking the smell might entice him. we've tried adding a little warm water. we've tried grounding up a hotdog, sausage link. we've also added canned dog food, but nothing. we did the supplements that our vet recommended, but we were spending $20 per week on JUST that one container, so we were spending $80 (which added up to over $200 a month on food and supplements) a month and the second we ran out he stops eating.
