A 16-week-old 18-kg (40-lb) sexually intact male Rhodesian Ridgeback was examined because of progressive tetraparesis and ataxia after a sudden onset of signs of neck pain while the dog was digging in the yard 4 weeks earlier. According to the owner, a sibling of this dog was reported to have died as a consequence of a cervical vertebral fracture, but no records could be obtained for evaluation. A CT scan had been performed at another institution and 2 other veterinary hospitals were consulted before this evaluation. A general physical examination did not reveal any abnormalities aside from excessively worn nails on all 4 limbs.
