Thank you for getting back to me. That means her back end has become paralyzed. There are a number of potential causes.
It's common for injury to the spine, pelvis, or limbs to result in hind leg paralysis. A rabbit can easily be injured. Just jumping and twisting the wrong way while playing can cause a serious injuery. Sometimes administering corticosteroids can help the rabbit heal.
Arthritis is another possible cause, but in a rabbit as young as yours, this is less likely. It can be treated with Rimadyl and/or glucosamine supplementation.
Degenerated or ruptured vertebral discs also cause this condition.
The sporozoan parasite, Encephalitozoon cuniculi, is yet another possibility. It is treated with anti-parasitic medications, such as febendazole. This is a very common infection in younger rabbits.
Here's a site with much more information on hind leg paralysis and weakness:
You'll need to take Asher to a rabbit vet to diagnose the problem. A hands-on exam, and probably x-rays will be needed to reach a diagnosis. The above causes are very different in their treatment, and the necessary drugs are available by prescription only. Here's a directory that will help you find a rabbit vet near you:
In the meantime, let her rest. Be sure to keep her food and water within easy reach. If you have further questions, just let me know. I hope Asher will recoverquickly.
