Most people mistakenly believe that Frontline
repels fleas and ticks from their dog's body. Frontline works by staying under the top layer of the dog's skin
and killing the flea or tick after it tries to penetrate the surface of the skin. Frontline kills up to 100% of adult
fleas within 24 hours and also contains an ingredient that kills flea eggs and larvae to keep all stages of fleas from developing
and bothering your pet and family. It also kills all stages of four major ticks including the one that may carry Lyme disease. Frontline is administered
based on the weight of your dog.
