My bulldog - Punk - has been having seizures for the past 6 months. She sits down - starts to bob her head up and down and acts like she is trying to bite something. She also moves her head side to side while bobbing it up and down. Has anyone else had this problem. The vet says a seizure and has her on phenobarbital, but I've also heard that this is common with bully's. Please let me know your thoughts. Thanks
