My parents dog had a litter of puppies and we gave all of them away. We gave one to a neighbor and a few weeks after we gave the puppy to her, she said the puppy was getting sick. We had already given puppy his parvo vaccinations, so we were pretty sure that it wasn't parvo. Anyways, the neighbor started giving puppy penicillin and another antibiotic, and she was giving it to him about two times a day for almost 2 weeks. Also the puppy was getting fed with a big dog and we are pretty sure he wasn't getting hardly anything to eat. They gave the puppy back to us and wanted us to put the dog down. When we got him, he could barely stand up and had a consistand tick in his head, almost like he couldn't hold it up. He also could not keep his balence. We decided to try and nurse him back to health. We stopped giving him any meds and started making sure that he ate. The first time we tried to feed him, he acted like he hadn't ate in years, but he could hardly keep his balence and his head from bobbing to eat. It has been almost 2 weeks and he has put on some weight, and his tick has calmed down a bit, but is still there and he still walks funny. He can hear us and see us, but can't walk straight to us. Also he is very stiff, almost like his joints don't bend like they are supposed to. We were wondering if maybe they overdosed him on medications and damaged his brain, or if that is even possible? We love puppy very much, but are not sure what we can do for him. Any ideas would help us greatly!! Thank you!!
