For collies, and indeed anything with a leaky blood-brain barrier, don't.
Ivermectin works on a receptor in the CNS. Invertebrates don't have a
blood-brain barrier, and get poisoned by ivermectin. Most vertebrates have
the barrier, and are OK.
Collie dogs have a blood-brain barrier that is just leaky enough to let
through ivermectin. The result is that a collie will die if given
ivermectin, from having its skeletal muscles locked solid.
This, BTW, is another caveat. Ivermectin makes invertebrates go rigid. If
the animal you are going to treat is extremely heavily infected, then its
gut may get blocked by "frozen" parasites with ivermectin.
