Get your dog to a vet. Our labrador's hind legs were paralyzed one morning and we could not get her to stand or to move. We called the vet and he mentioned that it could be neurological and had she eaten any nuts. We said no and as we were getting ready to leave, we found that she had thrown up nuts during the night. We have absolutely no idea where they came from, but there they were. After some investigation, we found that hazelnuts and in some dogs, peanuts induce spontaneous paralysis and most dogs recover within 48 hours as the toxins leave their system.
