While we're here, the reason the vet told your aunt that her dog should stay away from horse's ivermec is because the dose is much more concentrated for horses and dogs can be easily overdosed by such concentrated doses. Many people see the same drug name and don't pay attention to concentration so there are lots of instances of people dosing their dogs with horse ivermec since they have it already and it causes severe illness or death. It's just the difference in concentration that's the concern, not the drug itself.
Collies and some other herding breeds have a genetic predisposition to being sensitive to ivermectin due to lack of a liver enzyme to metabolize it properly. I could go on about it, but it'd probably be boring. PM me if you'd like to know more. I just wanted to clear up that issue real fast in case people were curious.
