Veterinarian ivermectin, dog food,etc can, theoretically, be consumed by humans. But one very important thing that nobody talked about here, is that these products are designed with non-human bodies in mind, which means that they pass through different quality control standards (normally way more lax than the human stuff), and might contain ingredients that might cause unwanted reactions or adverse effects, because us humans were not supposed to be consuming them in the first place.Also the dosage, in ivermectin's case, was calculated with a horse's metabolism in mind, so remember that a horse is several times taller and heavier than you, and has a different immune system (horses can be only mildly annoyed by a dose of rattlesnake venom that could kill a normal human, that's why their plasma is used to manufacture anti-snake serums.)

That's why I'm strongly advising against consuming horse ivermectin unless you strongly suspect you or someone close to you has the coof, and you made sure you exhausted every other possible way of getting yourself any regular HCQ or ivermectin pills. Stay safe, be smart. And God bless you all, patriots
