I had a chocolate female who started having IBD symptoms at about three months of age and was one sick puppy - vomiting and diarrhea every time I tried to wean her off hamburger and rice back to puppy food. She had an endoscopy and was diagnosed with IBD. She ate Hill's ID for about seven years, but then she became intolerant of that protein source. I then switched her to a duck and potato based food - I think it was IVD brand. She did really well and lived to be a few weeks short of thirteen. I had to be extremely careful that she only ate the dry and canned of this food and nothing else. I would cut up and freeze the canned food to use as treats. Strangely enough, she tolerated rawhide. Over the last years of her life, my vet had me put Tylan powder in her food, which helped also. Good luck with your IBD pup.
