Can anyone who owns owns English Bulldogs tell me if seizures are common in them? I have one that developed seizures at the age of 3 yr. old. She is on Phenobarbital and it was doing fine for 6 months now, and 2 months ago she had one again and then yesterday she had another one. Is it hereditary?? She's spayed but just want to know. Will her doses keep going up in the meds. She's not very active at all and just keeps gaining weight. She is on a low fat diet also.
