For the last 13 years I have used frontline. In those 13 years, I have had not one single flea and not one single tick. I'm a firm believer in the product, and I enjoy having no bugs on my dogs or in my house. I don't like bugs, and I don't like ticks. I especially do not like lyme ticks and since I live in an area heavy for the lyme tick, I am a firm believer in both the frontline product and also have the house sprayed quarterly for a bugs. I use half doses. Frontline is even safe to use on my epileptic dog, according to his neurologist who is world renowned. My dogs immune systems are nice and strong -- at 13 they act and look like babies. Good luck, I don't trust the natural stuff and it doesnt work.
