4 days ago my 7 week old siberian husky puppy was vaccinated and dewormed. He did not eat or drink for almost 36 hours. We took him to the vet and he was put on ivs because he was dehydrated. The next day he was back to being very sleepy and not the same. We took him back to the vet and he was tested for parvovirus and thankfully he doesn't have it. The vet we seen gave him to medications to help settle his stomach and we have been feeding them to him by syringe. Yesterday he started passing more worms and throwing up and not eating and barely drinking. Is it possible that he could still be passing more worms? His brother is fat and healthy and playing all the time
