First, you should never feed ham to a puppy. Did you get him from a breeder or pet store? He is very young. How much does he weigh? He should be eating a proper and good quality dog food. Stay away from human food. He needs to be vet checked and I see you have an appt tomorrow. That is good. You can buy nutrical to keep your puppy's blood sugar from dropping too low. Have you checked his gums to see if they are nice and pink?
