I use Deep Woods Off on Maxine and JackCode:
I would be careful, make sure they don't lick that off. That can't be very healthy. I use the Frontline plus, anything you get over the counter is crap. I don't give the Lyme shots anymore. Lilly has gotten it even though she has been vaccinated, and I have heard the same thing from several other people. It can also have some really bad side effects. I use Frontline and check my dogs daily.
