Heartworm Medication for Dogs FAQs

How do dogs get heartworms?

Dogs contract heartworms through mosquito bites carrying infective larvae. Once inside the body, larvae mature into worms that live in the heart and lungs, causing severe health issues. Monthly preventatives eliminate larvae before they develop into adult heartworms.

Can heartworm disease be cured in dogs?

Heartworm disease can be treated, but the process is lengthy, expensive, and poses health risks. Prevention with vet-approved medications is the best approach. If diagnosed, treatment involves injectable drugs and strict activity restrictions to prevent complications.

What happens if I miss a dose of heartworm prevention?

If you miss a dose, give the medication as soon as possible and resume the regular schedule. Missing multiple doses increases the risk of infection. A vet may recommend a heartworm test before restarting prevention to ensure no infection has developed.

Do indoor dogs need heartworm prevention?

Yes, indoor dogs are still at risk because mosquitoes can enter homes. Since a single bite can transmit heartworms, year-round prevention is essential, regardless of whether a dog spends most of its time indoors or outdoors.

Can heartworm preventatives treat existing heartworm infections?

No, heartworm preventatives kill larvae but do not eliminate adult worms. Infected dogs require a specialized treatment plan from a veterinarian. Routine testing ensures early detection, and continuous use of preventatives stops further infections.
