Heartworms are deadly parasitic worms transferred by mosquitoes that can infect the hearts and lungs of dogs and cats. Heartworm prevention should typically start around 6 to 8 weeks of age and be administered monthly to pets for the rest of their lives. We recommend testing dogs semiannually for heartworms.
Although heartworms can be treated in dogs, it is a long, difficult, and expensive process. There is no treatment available for cats. Because of this, we emphasize the importance of preventing heartworm disease before it begins. We have multiple options for prevention of heartworms to make the process quick and easy for you and your pet.
