My 12 1/2 year old Beagle has recently lost the use of her rear legs. We took her to the vet where she stayed over night. She is now home on medications. Has this happened to anyone's Beagle? And have they recovered without surgery.? I only left her in the Vet's for one night because she is very uncomfortable around other dogs. At her age I don't want to put her thru the trauma of spinal surgery.
