FRONTLINE Shield for Dogs, from the number 1 name in flea and tick protection (1), is the fastest working FRONTLINE product. It is proven flea and tick protection with repellency action against ticks and mosquitoes. FRONTLINE Shield repels ticks that may transmit Lyme disease and mosquitos that may lead to heartworm disease.
