Just put in a call to my vet. Chushing sounds almost like what he has.
Unless your dog has been getting to much Prednisone I doubt it has cushings. I haven't heard of any symptoms in your post that would lead me to believe this is the case. Cushings can be brought on by over adminstration of glucocorticoid drugs like prednisone. Otherwise it is usually a tumor or old age that can bring it on.
