Frequently Asked Questions About Heartworm Prevention for Dogs

Do most dogs survive heartworm treatment?

Yes, dogs have a good chance of surviving heartworm with the proper veterinary treatment, although the disease is still challenging to effectively treat. To avoid the costs, risks, and discomfort associated with the treatment, early heartworm prevention for dogs is crucial.

How long can a dog go without heartworm pills? 

Heartworm prevention medication should ideally be administered to your dog every 30 days. If a dose is missed, you’ll have 15 days to administer the dose before your pet is likely to become infected.

Where is heartworm in dogs most common?

In the United States, heartworm is most commonly found throughout the Atlantic and Gulf coasts stretching from the Gulf of Mexico up to New Jersey and all along the Mississippi River. However, heartworms have been reported in all 50 states, so it’s important to stay vigilant even if you do not live in the above areas.

Can I treat heartworms at home? 

No, you cannot treat heartworms at home. Once a dog is infected with heartworm, they will need medication administered by a health professional such as a veterinarian. It is not recommended to attempt to treat your dog for heartworm by yourself as it can be highly dangerous for your pet.

What are the first signs of heartworms in dogs? 

When testing for heartworm disease in dogs, some early symptoms may include a mild cough, lethargic behavior, weight loss, decreased appetite, and trouble breathing. In prolonged cases of heartworm, pets may begin to develop heart failure in addition to a swollen belly caused by excess fluid in the abdomen. Be sure to have your dog tested annually and use heartworm prevention medication to ensure your pet does not suffer irreparable heart or lung damage.
