I was feeding my dog gravy train along with his dry dog food and had to stop using gravy train because it gave him gas. He now will not eat his dry food until he is absolutely starving which is every 2 days. Anything I can buy to add to his food so he will eat it? I have tried that gravy stuff you add to the food to make it taste better, but apparently it does not make food taste better, or I have a very picky dog. I think it is the latter. I have not found a canned dog food that does not cause gas yet..... Picky and sensitive stomach I feel like I am trying to please the Queen of England! (god bless her)
