Our goal is to provide safe, reliable and appropriate parasite control for your dog and cat. We also want to protect your family from exposure to intestinal parasites and prevent flea infestations of the home. Every dog and cat needs protection from heartworm, roundworm, hookworm and flea infestation. Why are these parasites singled out for prevention? It is because they are potentially fatal or difficult to treat (in the case of heartworm) or because they infect people (roundworm and hookworm) or because they are an uncomfortable skin irritant and can transmit disease (fleas).
