I am curious to know which one you use. I am obsessed with my dogs, I treat them as though I gave birth to them (I do not have children). I know there were issues with one of the brands some time ago.
So which one do you use and have you had any problems with it?

We've been using Frontline for a couple of years now on my dog and 2 cats and it works great, I can't remember the last time I pulled a tic off or saw a flea on any of them. It's a once a month treatment, I order it from 1800petmeds.com.
