Was surprised to see this as  we are currently nursing a 12 week old herding dog puppy, who has had suspected Ivermectin Poisoning.  Apperently fairly masive does of Ivermectin are routinely used to deworm horse, and the pup probably got an accidental dose eating some horse poop that was tracked into the farm home where she was born.  the breeder deliberatively does not use Ivermectin on her own horses,  but there was a horse show at the farm around the time the pup was born.  We have also to be careful to not use ivermectin heart worm medication with our other herding dogs.

Why is this product sold (over the counter apparently) for horses if Humans who need it cannot get it?
