We have about 75 fox hounds and all get ivomec for prevention of heart worms 1/10 of a cc per 10#'s of body weight you can either inject it or give it orally what ever you prefer but I think any tye of collie or close relation you have to be very careful with what you use to prevent heart worms even some of the more expensive products on the market say to not use this product on collies.
