"My doggies LOVES his Collagen Bully Sticks. This month, however, there seems to be a new ingredient added which gave him diarrhea. I haven't given him a bully stick for a few days and the diarrhea has subsided and waiting to see if he reacts with diarrhea when bully stick reintroduced. Did you change ingredients or use something from a different supplier??? If not for current issue, I would give his Bully Sticks a resounding score of 10."
