Ever since I started to feed Milo on the raw diet 2 months ago. He has vomitted his raw chicken meal out twice since. The first time was after I played fetch with him after his meal, and the second time was about 5 minutes after he finished eating (didn't play or run). I checked the vomit, and it was still undigested raw chicken. There weren't any foreign suspicious objects in the vomit. The bones were well crushed up and the meat were not in clumps, so he did chew it well before swallowing.
1st vomit meal: quarter chicken
2nd vomit meal: whole chicken carcass
My question is, does chicken have a higher risk of stomach upsets? Is there something wrong with the chicken?
