Help Little Leo’s Legs!!

Monday night, little Leo was running around in the backyard and slipped hard. His hind legs gave out and he was spontaneously paralyzed from the mid thoracic down. This random incident has shocked his owner and the medical bills are mounting as veterinarians are determining how this traumatic spinal injury happened to such a young dog so quickly. Any help you can provide would be much appreciated as this will most likely be a long journey for Leo.
