In the News

The American Heartworm Society is the leading resource on heartworm disease, and our mission is to lead the veterinary profession and the public in the understanding of this serious disease. Every year, hundreds of stories are written on the diagnosis, prevention and treatment of heartworm, as well as on the plight of affected pets. These stories are an important way of reaching both veterinary professionals and pet owners with information they need to know about heartworm disease.

The American Heartworm Society is led by a board of directors comprised of veterinarians and specialists in the fields of veterinary parasitology and internalmedicine. As leaders in the fight against heartworm disease, they are available as resources and authors of related stories.

Paola Domínguez-López on the importance of embracing change

Paola Domínguez-López has always been passionate about animals. Her big dream as a child was to be able to care for animals in need, especially those who don’t have a home to call their own. 

Her parents helped foster her love of animals through agriculture programs like 4-H. As time went on, Paola realized that veterinary medicine was the right choice for her, eventually enrolling in the Veterinary Nursing Program in St. Petersburg College. 

While studying to become a veterinary nurse, she also began volunteering for animal shelters. This eventually lead to a job at a local animal hospital, where she eventually became a vet tech.

She now combines her nursing skills and her passion for shelter animals by working her dream job at University of Florida Small Animal Hospital. She currently works in the Veterinary Community Outreach Program of the shelter medicine department. This allows her to help shelter animals in need while doing the job she loves.
