Yes, I join you with the itchy dog problem. My maltese has suffered dearly already this summer,with biting and scratching. I too used Frontline Plus, which used to work on her, but even re-applying it within the 4 wk period didn't work. I looked at one of the Ads here and one of the products was Emu Oil. So I read what it does and I bought the small bottle for $11 and it really works. So try some Emu Oil.
