We just brought home a 4 month old puppy who is an English bulldog/Olde English Bulldog. We picked him up from an Amish farm (We didn't know when inquiring ) and 3 days later he threw up worms and had mucus diarrhea. Took him to the vet and he was diagnosed with pneumonia, roundworms and coccidia. The vet gave us medication and he seems to be doing better 10 days later. Our concern now is he has no motivation to go outside. He refuses to get out of his spot or wherever he is. We have to pick him up and bring him outside of the door. We have tried treats to reward him but he refuses to eat them and then we praise him but still nothing. He has been peeing and pooping in the house as soon as we come back from the walk. We though he might be stressed out so we walk him at times when theres no one around. We don't do long walks either. We are not tugging at the leash. We have also left the harness and leash on him so he can be more comfortable with it. Also he doesn't respond to his name or any commands he will just look at you and stare. Our concern is is this because of the medication? Just him being stubborn? What other motivation can we do?
