Heartworm prevention protects dogs from a dangerous and potentially fatal disease. Choosing the best product keeps your dog healthy and happy.

Heartworms spread through mosquito bites and live inside a dog’s heart and lungs. They cause serious damage and can be deadly if untreated. Preventive medications stop heartworm larvae from growing into adults. Many options exist, including chewable tablets, topical treatments, and combination products that also fight fleas and ticks.

Some popular choices are HEARTGARD® Plus, NexGard Plus, and Interceptor Plus. These products suit different dog sizes and needs. Regular use, as directed by a vet, ensures full protection. Selecting the right prevention helps avoid costly treatments later. Keep your dog safe by using effective heartworm preventives year-round in areas with mosquitoes.
