Show them how much you love them by protecting their hearts.

Almost 300,000 dogs in the U.S. are infected with heartworms each year.¹ Adult heartworms can cause heart and lung damage, even death.

Common symptoms include coughing, lack of energy, labored breathing, and weight loss.

Prevention is key.
Using a heartworm preventive like SENTINEL® (milbemycin oxime/lufenuron) Flavor Tabs® on time every month is the only way to be certain your dog won't catch this painful, potentially fatal disease.

One mosquito bite is all it takes to infect an unprotected dog.

Heartworms are transmitted by mosquitoes year-round and are found in dogs that live indoors and outdoors.²

SENTINEL Flavor Tabs kill heartworm larvae before clinical signs of disease occur.

ALWAYS have your dog tested for heartworms before starting a preventive regimen. Giving a preventive to a dog that is already heartworm-positive can cause further complications.
