Hip and Back Injury to Dog : My 3 months old labrador male pup had fallen from first floorn to ground floor and received severe back and hip injuries. his rear legs became senseless. vet treated him and dog regained full senses in rear legs. he can not walk on four legs and thus drags himself with the power of front legs. he can not stand on rear legs at his own but if make him stand by support then he tries to walk but urintes due to pain and is unable to move rear legs. his both hip joints are either broken or are dislocated. now he is one year old and has become bulky. we are still serving him in the hope of getting him cured/healed. It is my request to everybody to help me in this matter by giving your valued advise, suggestions, tips to get my dog walk on four legs at least with some restrictions. Thanking you .... Pratap Singh
