I switched to Nexguard a couple months ago (chewable).
Frontline wasn't doing the job for my lab, and I hated having the stuff in his fur with my kids around him (right after it's put on him and it's wet).
So far, so good. I won't REALLY know till fall when he's in the brush and weeds hunting birds. It seemed last year the the ticks here (southeast PA) weren't horrible in the woods, but in grass/weeds, they were horrendous.
