So what sort of parasites could cause higher level of Eosinophils? Or if not parasites, what would? I have a dog with seizure disorder and can't help but think they are linked; but I de-worm with ivermectin and fenbendazole monthly. Or can the slightly elevated levels be caused by something else? His sister died of seizures with no drug working and now he is starting to develop more episodes even though he's on phenobarb.
What's her Eos count? Percent on the diff? I wouldn't spend any time worrying about a slighly elevated count. I spot check bloodwork on my dogs very frequently and I'll get spikes lasting for a few months. Sometimes it's just a mild allergic reaction, sometimes a bout of parasites that will get taken care of the next time you deworm.
What's the phenobarb dose? You can add Kbro as well, it worked well for my boy with seizures. I really wouldn't consider a link betwee seizures and eosinophilia, it's probably just a coincidence.
