Heartworm Preventive Comparison Chart

Medications used to prevent heartworm infections are called preventives. Preventives kill the heartworm larvae before they have a chance to grow and mature into adult heartworms. A number of heartworm preventives are available to pet owners today. Some heartworm preventives contain additional ingredients that will control other parasites, such as roundworms or hookworms. A monthly preventive should be given to all pets. Remember that mosquitoes, the transmitter for heartworms, can get indoors and therefore your  pet is still susceptible even though he or she may not go outside.
