Just make sure that you use the Frontline that is for the weight your Yorkie is.......6 lbs. Along with Frontline you need to use some sort of heartworm preventative such as Heartguard. I use Revolution and that has the heartworm preventative in it. My 12 yr. old, Rosie, can't tolerate Frontline. It gives her the shakes and she is sick for several days after. And blessings for taking this little baby in. ~Joanne~
