Most of us are very concerned about the flea problem in most areas. I know I am. Fleas are not only uncomfortable for our dogs, but they can cause illness, hair loss, allergies and so on. I discovered Advocate a couple of years ago. It is a relatively new product that is a once a month treatmet that is put between the dog's shoulder blades. It will get rid of any fleas within 12 hrs. (usually I've seen them gone in far less). It also gets rid of round worms and helps in the prevention of heartworms, hookworms, whipworms, sarcoptic mange, and ear mites. Since I have been using this product I have not had a dog with any type parasite, ear mites or heartworms. Oh, yes, as long as I use it each month, they do not have fleas. In very heavy flea season, I have had to use it at 3 week intervals, to keep the fleas off. Wonderful product - and very reasonably priced.
