Can a dog recover from heartworm disease?

Yes, dogs can recover from heartworm disease if you catch it early and follow the full treatment protocol from your vet. Treatment takes several months and requires strict exercise restriction, but most dogs go on to live full, healthy lives after recovery.

Do indoor dogs need heartworm prevention?

Yes, indoor dogs need heartworm prevention too. Mosquitoes get inside homes easily, and it only takes one bite from an infected mosquito to transmit heartworm larvae. Vets recommend year-round prevention for every dog, regardless of how much time they spend outdoors.

How often should my dog be tested for heartworms?

Most vets recommend an annual heartworm test even if your dog is on year-round preventatives. If you miss a dose or live in a high-mosquito area, your vet may suggest testing every six months. Puppies under seven months can start preventatives without a test, but should be tested six months later.

What happens if I miss a monthly heartworm dose?

Give the missed dose as soon as you remember, then contact your vet for guidance. A single missed dose can leave a window for infection, so your vet may recommend a follow-up test six months later. Never double up on doses, and do not skip prevention just because you missed one month.
