It is possible that this is not a problem for Tony, especially if he has done it for a long time. However, quivering of the jaw could indicate pain at the TMJ or dental disease. I would recommend that Tony be checked over by a vet to make sure there is no obvious problem that can be treated to resolve the quivering.
