Can't use the back legs in rabbits
What this sign can mean and when to act, from House Rabbit Society and RWAF guidance. This is general information, not a diagnosis.
This can be a rabbit emergency.
This may be a veterinary emergency. Call your exotic vet now, or go to the nearest emergency exotic vet hospital.
What it can mean
Because inability to use the back legs is a vet emergency in rabbits, the vet's exam matters most, but it can be associated with a spinal fracture or dislocation (which can happen from a single wrong kick or fall), E. cuniculi causing progressive rear-limb weakness, severe arthritis, or a spinal tumour. Do not try to move your rabbit's hind end forcefully. Keep them calm and get to an exotic vet immediately.
