My Cav Hunter is 2 1/2 and has all the symptoms of SM. We just brought him to the vet last week and blood was negative so off to the neurologist tomorrow. He fly catchers constantly, scratches, shakes his head, digs at the carpet, lies on the tile floor. We are so upset that this is happening; he is on medication for seizures and anxiety. What medication will help and will he live a normal life on medication? He doesn't want to play anymore and it is the saddest thing.
