Heartworm

Heartworm is a preventable but serious parasite that’s potentially fatal if left untreated.

Though it’s endemic to all parts of the continental US, heartworm is most common in the south and southeastern parts of the country. Adult worms live in the heart, lungs, and blood vessels of affected dogs, causing severe damage to these organs and others. The worms can contribute to congestive heart failure, which often results in death.

The American Heartworm Society recommends all dogs be maintained on year-round monthly preventative and annual testing. Puppies should start heartworm prevention as early as the product label allows but no later than 8 weeks of age. All heartworm medication — whether topical, oral or injectable — eliminates both the larvae deposited by the mosquito as well as the stages that develop in the dog.

If your dog tests positive, there are treatments available to kill the adult worms. You’ll want to confirm the diagnosis, stabilize your dog if they are showing signs (e.g. difficulty breathing), limit exercise, and work with your veterinarian to determine the best treatment plan.
