I recently talked to this sweet old lady at a local dog days event who had leonbergers. So we got to talking and she said that she has always given her dogs brewers yeast for flea and tick, and has never had a problem with heart worms. i have done some research on it but i wanted to check here and see if anyone had any more insight to see if its too good to be true before i switch from the frontline and heart worm meds.
