Hi there! So, I am super frustrated and not sure what the "right" thing is to do for my boy. Since he was about 12 weeks old he has been super picky with his food. We added milk on top of his kibble ( breeder recommended) to help him eat it and to put a little weight in...we didn't continue that for long since it caused GI upset. He has always struggled with weight....very thin with ribs and hip bones prominent. I have switched around kibbles in hopes to find the right one for him. Intermittent trouble with loose stools and gassy, also red rash skin on belly. He was diagnosed by his vet with IBD based on diarrhea and blood work done (B vitamin levels were very low suggesting malnutrition). She put him on Royal Canine Hydrolized Protien kibble, he hated this. He has been on that for about 7 months and really hasn't gained any weight....... he is 16 months old and weighs 42 lbs barely. I went to a small pet food shop and the guy said to put him on Annamaet 24% Option. He said no need to integrate the food, just make a complete switch. Well now Harper has really bad diarrhea and is going non stop when he's running outside. Although his trashy skin has gone away! I am just soooo frustrated. My gut tells me (no pun intended) that he really doesn't have IBD, just has sensitive belly. But I can't seem to get him acclimated to any diet. Maybe I am switching around too much and just need to give this switch time? Help please!!! (Photos below)
