Hi Jennifer,
Thanks for writing in the comments here. Let's get a couple of things established first, as I see some misunderstandings that are likely still very common among pet owners.
"If we vaccinate, there could be toxicity problems, if we don’t – there could be disease or other problems."
First, there can certainly be toxicity problems, but vaccinations carry much more insidious, long lasting, even inheritable effects. I wrote about that here, if you'd like to learn more.
Secondly, veterinary immunologists tell us that protection from the early shots lasts a very long time, perhaps a lifetime. So, if you're thinking "I'm damned if I don't!" you might want to visit this page to see how an adult dog doesn't need vaccinations. Nor benefit from them.
Third, seizures have been associated with vaccinations, certainly, and two in particular, whose diseases can include convulsions: distemper and rabies. Again, this is more than just intoxication, as that first link will tell you.
Then, you can Google seizures (or convulsions) and ivermectin, and see what you find. The common heartworm "preventatives" are neurotoxins, as I point out in my ebook, Vital Animals Don't Get Heartworms.
CBC's won't usually reflect acute intoxication, no. And diagnostics for "what caused those seizures?" usually comes up normal.
What to do? Pred is the subject of this week's blog post, called Instant Gratification. Does not and cannot cure anything. Period. Best to get a homeopathic veterinarian on board. You can start with the AVH list on my Resources page. See who does telephone consulting if no one is near you.
All the best, and try to keep learning through all of this. Knowledge is power, and you could use more now that you're on the cusp of a very difficult disease. I hope this helps.
