When I got barney I immediately changed his diet from puppy chow t chicken soup for puppies. I did this a little to quickly which was a stupid decision on my part. I started feeding him chicken and rice and his stool firmed right up. I started adding his food to it and he started getting it again. Is there a possibility that the food could be the problem I know it has several protein sources in it. Has anyone tried pepto bismol? He was at the vets the 10th of september and did not have worms. Should I give him the chicken and rice without the food or mabe try canned pumpkin or can I cut up a real pumpkin and add it to his food?
