Animals With No Use of their Hind Legs
Various congenital conditions and spinal injuries or degenerative conditions can paralyze an animal's hind legs. This hub is not so much about this unfortunate condition as the perseverance animals can show in continuing with their lives, regardless of what happens to them.
This pig has paralyzed back legs. It learned how to walk balanced on its front legs alone. (From the collection of Bernard Kobel). You can see some modern animals that have mastered the same trick here: Two-Legged Pigs.
This stray dog was spotted in Trinidad. It seems to have lost the use of its rear legs possibly due to being hit by a car, and developed a different method to get around bipedally.
Penny is a wonderful dog who learned to walk two legged after a serious injury. Please see her inspiring story here. She given treatment and eventually able to walk on all fours again!
On when level when you look at these animals it seems sad or even pathetic. They have been born disabled or been badly injured. But what I see is that animals have a gift for living in the moment. They have continued with their lives, and found a way to do what they need to do. Sometimes people could learn a lot from animals like these.
The main causes of this injury are:
- Physical trauma to the spine.
- Illness such as encephalomyelitis.
- Congenital defect.
Some animals can spontaneously recover from hind limb paralysis. There are also promising treatments under development including cell therapy. Development in veterinary medicine and treatment of paralyzed animals may eventually contribute to developments in human medicine also.
The stories of these animals are:
