Dogs are most at risk for contracting heartworm, but it can also affect cats. Understanding the condition with these frequently asked questions will help you better protect your pets.

FAQ About Heartworm

What is heartworm?

Heartworms are parasites. When they enter the bloodstream, these tiny worms can latch onto an animal’s heart, lungs, and arteries. They eventually mature, grow up to a foot long, and produce offspring called microfilaria. If left untreated, heartworm disease can lead to serious heart problems and even be fatal.

How is it transmitted?

Dogs and cats don’t transmit heartworm directly to one another. It’s most often carried by mosquitoes. When a mosquito bites an infected animal, it can pick up microfilaria and transmit them to another animal.

What are the signs?

Early stages of heartworm don’t come with any visible signs, so it’s important to schedule regular blood tests with your veterinarian to make sure your dog or cat is healthy. Also, look out for low energy levels, coughing, and discolored gums, as those can be signs of later stage heartworm.

How can I prevent it?

Have your pet tested for heartworm every year to make sure they’re free of parasites. Your vet may also recommend a heartworm prevention pill or topical treatment. These options work by killing the larvae of these parasites before they mature and latch onto your pet.
