Our male Corgi, from age 4, started having seizures regularly after accidently given two doses of Heartguard on the same day (am & pm). Found out later that Collies are very sensitive to Heartguard. Our Pemb Welsh Corgi was a white and tan. This mixture came about by inc the Collie breed. My vet never said a word about this. Later we ended up having to put our Corgi on Phen Barb and potassium bromide. After starting him on this nasty combo--his seizures all but stopped, but then he came down with Degenerative Myopathy (we tried everything in the book before PB and PB).
Heartworm Meds and Seizures
Heartworms are epidemic in the Gulf Coast area. Dogs WILL get them if no preventative is used. My problem is, I suspect Heartgard is the reason for my Border Collie/Pointer's seizures that have started at 5 yrs old. I'm switching to ProHeart, which use a less toxic chemical, and I'm using a smaller dose than is recommended. I'll have her tested in a couple of months and again after the first big cold spell of 2010, but I'm guessing she will be heartworm free. In addition to decreasing the toxicity of heartworm meds, I'll be using herbal remedies as a back up. If you don't live in this area, you have no idea how bad the mosquitos are. And I refuse to keep my 3 dogs indoors all the time because they need to be outside enjoying life. Good luck to everyone on this thing...
Heartworm Meds and Seizures
My Pug, Peanut, developed grand mal seizures after taking Interceptor heartworm medication. I took her off the medication immediately. She had one small seizure 2 months after coming off Interceptor. She is completely seizure free after being off the medication for the last 3 years. I do not give my dogs any heartworm medication as they are mostly indoor dogs. They have all tested heartworm negative even though I do not use heartworm medications.
In addition, after the seizure scare, I do not update my dogs' vaccinations. The dosages are too toxic. However, my dogs are mostly indoor dogs.
