Frontline causes seizures Beware of Frontline for Yorkies. It causes seizures after three or four months of use. Our little Yorkie had epilepsy, we thought, until we stopped using Frontline, and he hasn't had a seizure since. A little Frontline caused a little seizure; a regular amount caused three seizures. But it builds up in the system. The first three or four months, there was no problem, but afterwards, it was a disaster. Don'e use barbituates. Stop the Frontline. |
