Based on your description of symptoms and his breed, the top of the list suspicion would be a ruptured or buldging disc in his neck or back. These are very painful and can occur without any trauma or reason. In some cases, they will manifest as pain only but it can progress to partial loss of function of the legs or even paralysis. Cage rest is a big part of the treatment as well as anti-inflammatory meds and pain meds while the spinal cord swelling resolves. If it is not improving or if it is getting worse, surgery is sometimes an option.
