when my dog went for her yearly check up (it was a week before she turned 3 yrs. old) the vet told us about the shot for heartworm. I seem to remember the other times with the pill that they did a blood test first before giving the pill. Well anyway, seeing as we have a very bad memory for giving the pills once a month, we said go ahead. Three days later she started having seizures. Do you think the shot might have in anyway started this? It's too late for my dog she is already on medicine because they have become so bad, but if so maybe it should be something to look at. Thanks for your time.
Anything is possible, I can not tell you the heartworm injection caused the seizures b/c I do not know if it is true but I would definitely notify the manufacturer and let them know. Your vet may have already done this, I do not know. Vetcare
