My dog Ari has been having seizures for a couple years now. At first, they started out being twice a year, but as the years have gone by, they keep getting worse, the last time was so bad it was over 15 mins and had to be sedated to get out of it. Usually, after he has one, he has another followed by 12 hours or so. He is currently on Phenobarbital with a combination of other meds. Does anyone know how expensive veterinary neurologists are? And are these signs of brain cancer? Outside of the seizures he's perfectly fine, except the day he has them he seems a little off and right after he has them he's still a little out of it. Has anyone had something similar? Ari is going to be 11 in April. Thanks so much.
