Hello, I am new to this forum and new to yorkies. I am taking care of a family members Yorkie and I can not get rid of the fleas. I have treated the house and our Yorkie. We have tried Pet Armour which seemed to help for maybe 2 weeks and then the itching and fleas started again. Then we tried Comfortis this helped for maybe 3 weeks and now he is infested again. What is best for Yorkies? If Comfortis didn't help, should I try a topical like frontline? I was told by the vet that Comfortis would work wonders but it just didn't seem to work for this poor baby. Any helpful information would be greatly appreciated
