I hope this is an ok question to ask, but I thought since you all are learning about this or have been practicing I would ask. My dog has seizures, he's 5 now and they started when he was 2. I was using frontline religiously according to the instructions, but once the seizures started I discontinued their use. My Aunt said she used it on her cat and it started shaking, and behaving strangely. And a friend used too much on her dog and found a similar response but in both cases they washed their pet and within a week-month there were not other signs of abnormal behavior. My dog however still has seizures there don't appear to be any triggers and I'm wondering if I should focus on the frontline angle (from a toxicity standpoint) or that it might be genetic, or just random. Has anyone ever experienced canines developing seizures after using the product? I'm always researching possible causes/treatment that will prevent my little one from going through this any more than he needs to. Please excuse me if this is not the forum for this. Thanks!
