I would deffinately do a vet check. Chicken bones are a no no in my house, any bone for that matter. IF your pup shys away from food or water then that would be a big red flag, so would a foul odor like rotten blood. If that is not there, and he has no other symptoms of distress, i would monitor, it is possible a small piece of bone is causing the problem. When a dog does get a bone or i am not sure i give them a large quantity of bread in hopes that it will bind around the bone. I hope your pup is going to be ok. You should never ever have any reason that you could not call your breeder. They should want to hear if there are any problems at all.
