hi, im new to the forum and would like to gather and share information about yorkies. iv been using frontline for my yorkie and i never had a problem with it. it did clear up his flea/tick problem. accdg to our vet, the best way to apply frontline is to give my yorkie a bath. then after 2 days, apply frontline and leave it on for a week. this is supposed to maximize the effect of frontline. hope this helps.
