Poor Harley! In an old dog, I would be concerned that a seizure could be caused by low blood sugar, liver disease, kidney disease, or a brain tumor. I would take him into the vet today for an exam. It would be a very good idea to diagnose the cause of the seizure, and he may benefit from anti-seizure medications.
