Does your dog have any of these symptoms: weight loss, poor skin and hair coat, liver disease, vomiting
The reason I ask - diabetic neuropathy generally effects the rear legs....
I would suggest asking your vet if there are tests he can perform to help diagnosis this OR refer you to a specialist. I wish I could be of more help. I'm sure if anyone else has input they will post a reply to you also.
I do wish you the best. Let me know if there's anything else I can do.
