I stopped using Frontline Plus and started using K9 Advantix. Maybe just switching brands would help? Duke was still itching a lot w/ the FP, now he barely does w/ the Advantix.

If you are going to stick w/ Frontline though, make sure you're giving Frontline Plus and not Frontline Top Spot. Frontline Plus is better at breaking the cycle than the Frontline Top Spot.

You could also try the Capstar tablets to help for a little bit. They are about $3 a pill though and the pills are active for 24 hours. It's a quick kill though and helps while you clean your home, anytime you have to wait because you just bathed, etc.
