I spoke to frontline just now and their main ingredients are as follows:
fipronil
s-methoprene
She says that their product does not go past the oil glands. Whatever that means. I asked if there were reports such as the ones with Hartz and she would just repeat the same information. Guess she cannot say. I am rethinking the whole topical prevention all together.
Oh, damn. Now I get it. That must be why the instructions say to apply behind the neck, where they can't reach and digest the poison on their own body.
BUT what if you have more than one dog like me. The wrestle and bite the back of each other's neck all the time. THat is really scarey now that I think about it. |
