Heartworms 101

Heartworm prevention wrapped in cheese? Yay!

What are heartworm disease?

Heartworm disease is a serious and potentially deadly disease caused by foot long worms found in the heart and lungs of affected pets.

Who can get heartworms?

Heartworms can be found in domestic dogs, cats, and ferrets as well as wild animals such as coyotes, sea lions and foxes. Dogs are the natural host for heartworms, that means the heartworms live, grow, mate and produce offspring inside the dog. Cats however, are atypical hosts. Heartworm disease in cats can go undetected even while a single worm is causing life threatening damage.

How are heartworms transmitted from animal to animal?

Mosquitoes pick up microscopic baby worms (microfilaria) that circulate in the bloodstream of affected animals.These baby worms mature into “infective stage” larvae over 10 to 14 days. When the mosquito takes a blood meal from another pet, the larvae are deposited onto the skin of the animal and enter the blood stream through the mosquito bite wound.

How long can heartworms live inside a host?

Mature heartworms can live 5 to 7 years in dogs and 2 to 3 years in cats, with each infected mosquito bite adding to the current worm burden.
