I wouldnt normally answer these post as I think its guess work and a vet is required ,I have no experience of this but
would get your dog to the vets whichever vet is available from what little I do know white blood cells elevates when there is a infection of some kind .The weakness in the back legs could be because your dog is weak rather than them failing , in fact it could be anything if it was my dog.... I would be there today.
