I use 1 cc of ivermectin on large dogs once a month

Don't you mean .1cc? The proper dose is .1cc per 22 pounds of dog, though ivermectin is safe at somewhat larger doses. However 1cc would be a HUGE dose for a dog!

You also want to be careful what formula of ivermectin you use. They're not all the same!
