I used regular Frontline on all the dogs and on the cat (who doesn't go outdoors but who hangs out with the dogs all the time) and every animal in the place is now flea free except one Cavalier bitch, and all hers are on her head! Noplace else. I think that's weird...someone else told me to get the spray and spray the top of her skull and those'll be gone, too. Now, where's that spray bottle I got a while back............. In past years I'd used Advantage and then last year it didn't work...your "own" fleas do get immune and every few years you have to switch brands. Also I suggest using the Frontline spray when you have to...it works really well and sometimes is even better than the topical stuff. Peggy VDanhoffer@xxxxxxx wrote: >Fleas are horrible this year!
