Frontline Plus - Harmful to pups? I just applied Darwin's monthly application of Frontline Plus, however, he scratched it all over his back and back paws! I keep wiping his back paws each time after he scratches b/c he has a tendency to lick his paws. I'm nervous he'll end up swallowing the frontline...will this make him sick? Also, since more of the application ended up on his fur than his skin, will the medication be effective this month? |
