This is my first day as a member on this site, and am also still unclear about the navigation. However, our older bully, Diesel, experienced head shakes after we first rescued him. The vet we used, while a good doctor with an excellent reputation, was not really familiar with the EBAY breed. She had him on seizure medication and tranquilizers and, needless to say, he was a zombie. We could not stand it, so we found a clinic that had a bully specialist. He took one look at Diesel and correctly explained to us that the head tremors were not seizures per se, but were something typical of the breed. We weaned Deez off the drugs and replaced the treatment with distraction. His tremors are infrequent now (usually in the evening, if he experiences one) and we immediately distract him with a tiny training treat and the shaking stops. He's back to being our aging, but healthy, happy Bully! Hope this is helpful.
