Has anyone heard of Defend?

I just got off the phone with my mom, and she said she picked up some Defend for Major. I've been telling her we need to get him some preventative for fleas and ticks. She said that both vet places had the same stuff. Well, its supposed to keep away ticks, fleas and mosquitos away from him for 3 months. I'm really happy!! I hope it works. Ticks came out about one week ago, not even and I've already found SIX on Major!

Does anyone know if its a good brand and if it works?

Never hear of it, but I have been out of the states for 2 years now. I used to use Advantix on Drake. We just switched to Frontline Plus since the vet was out of Advantix. Both products work very well. Not a flea or tick on him since he has been using it. Almost 3 years!
