Hello,
We are originally from MA but now in SLC, UT. My B's have always been on Heartguard meds and we do it all year long and I have my B's test every two years. Results have always been negative. My 6 year old male B (Grady) started having seizures 6 months ago (summer 2013). We immediately went in for blood work and a vet check - no significant findings. I've been watching them more closely now and try to document everything I can…food intake, toxins, weather conditions, what happened that day of a seizure, stress triggers, etc. Grady has had 5 seizures and they are spread out since last summer. The seizures usually happen when we are asleep at nite and luckily only last a few secs to a minute or so. I want to AVOID medications for as long as I can and have started him on vitamins/antioxidants to increase his immune system. He is still a fun-loving goofy crazy dog otherwise. We were on Heartguard plus (chews) years ago but then converted over to Iverhart Plus for the past few years. Both my dogs have been on it but Grady has the seizures and my 13 year old female B hasn't show signs of seizures. She is going through the senior dog stages ... like more whitening near her nose, slowing down, getting sore easily, etc...but no seizures. I'm thinking that the "ivermectin" in the Inverhart may cause seizures and if this is the case...perhaps Grady has become very sensitive to this med since he has been on it for most of his life....I need to take him off of it and try something else for the heartworm prevention. I'm still hoping I can find out the cause of his seizures. Anna
