Jaeger who is alittle over four months has been vomiting for a few days now. Not all the time but enough to make me concerned. His vomit is mostly undigested food. We have been to the vet. Blood work and physical were normal, urine sample normal. We started on worming medication and he was given SQ hydration just in case but the vet said she could not see why he would be having these problems. We haven't changed his diet and I didn't think he has eaten anything he shouldn't have. He acts fine, like a puppy should and does not display any signs of discomfort. He is eating but not like he has been and he is having bowel movement although they are now more diarrhea. Two vets have said they think it may be food related (but his diet hasn't changed) or worms which the medication should take care of. Apart from a x ray they said I should just watch him. I'm concerned because of the undigested food, not eating as much and now the runny stools. Any suggestions?
