I have an older female shih tzu mix dog which is VERY resistent to baths and haircuts. Groomer suggesting taking to a vet place for cut as Petsmart could not get it done. Thursday the vet place attempted cut, but they are saying dog fought much and had 2 seizures (as they called it). They also mentioned once the dog maybe fell but they didn't want to talk about that. So they quit trying to cut. After getting the dog home, she could not walk, legs collapsed when trying to walk, was extremely tired looking, and hasn't eaten in 3 days. She does drink a little water. Friday, she could walk 30 or 40 feet ok, but then gets tired out. I took her back to same vet this morning (saturday). they took blood tests and will have results monday. I really don't know what the purpose of a blood test is, as the dog was in reasonably good condition for her age before the grooming incident. Anyone have any suggestions as to cause and treatment?
