Write a short informative piece about heartworm infection in dogs
gpt
Heartworm infection is a serious disease that has the potential to result in organ damage, heart failure, severe lung disease, and death. Dogs residing in areas with high populations of mosquitos, which carry infectious heartworm larvae to new hosts, are at risk of infection from heartworms. 

Heartworm infection presents with various symptoms, including a mild yet persistent cough, weight loss, fatigue, decreased appetite, and exercise reluctance. As the infection progresses, dogs may develop swollen bellies due to excessive fluid and heart failure. 

The best way to prevent dogs from heartworm infection and disease is to test them regularly at a veterinarian and provide them with monthly heartworm prevention.
