5 Facts Pet Parents Need to Know About Protecting Pets From Heartworms

(StatePoint) Heartworms are one of the most common and serious health threats faced by pets. According to the American Heartworm Society, more than a million U.S. pets are infected with heartworms, and incidence numbers are rising—even though heartworms are easily prevented. To equip pet parents to provide the protection their four-legged family members need this summer and year-round, the American Heartworm Society is sharing five vital facts about this deadly threat.

1. A single infected mosquito can spread heartworms to multiple pets. Heartworms aren’t spread from one pet to another. Instead, they are transmitted when a mosquito feeds on an infected animal, such as a dog, coyote, fox or wolf, then later feeds on other susceptible animals and pets. Within months, heartworms grow from tiny larvae into foot-long adult worms that live in pets’ hearts, lungs and blood vessels.
