Heartworm Testing in Lake Buena Vista, FL, From Your Local Vet

Mosquitoes spread heartworm, and Central Florida has mosquitoes almost all year. That's why most vets here test every dog once a year.

Why test a dog that already takes prevention?

Because no prevention is perfect in real life. A dose gets missed, a chew gets spit out behind the couch, or a dog visits a groomer during a gap. If your dog has heartworm and starts or keeps taking certain preventives, the dying worms can cause a bad reaction.

A yearly test also protects you. Most makers of heartworm prevention will only back their product if your dog was tested on schedule.

The American Heartworm Society's 2025 incidence survey put Florida in the top ten states for heartworm cases.

Which dogs need a heartworm test?

• Every adult dog, once a year, even on year-round prevention

• Puppies 7 months and older, before or soon after they start prevention

• Dogs who missed a dose or went a month or more without it

• Dogs new to you, such as a rescue, with no clear record

• Dogs moving from another state or a long trip, before you change products

Puppies younger than 7 months usually start prevention without a test, because the test can't find an infection that young. The vet will plan a test later.

How is my dog tested?

1. A team member draws a small amount of blood from a leg.

2. The in-house test checks for heartworm and, with the same sample, common tick-borne diseases.

3. The vet goes over the result with you, often before you leave.

4. If the result is positive, the vet will explain the next tests, such as chest x-rays.

Across Petfolk, this heartworm and tick-borne disease screen was the most-ordered in-house lab test (Oct 1, 2025 to Sep 30, 2026). It's quick, and Fear Free handling keeps the draw calm.

You'll get an estimate before any test or treatment. The final bill can differ if the plan changes during the visit.

If the test is positive

Heartworm disease can be treated, but treatment takes months and needs strict rest. The vet will walk you through each step, from more tests to a plan for keeping your dog calm. Catching it early makes treatment simpler and easier on your dog. That is the whole point of testing every year.

Early heartworm often has no signs at all. As it grows, you may notice a soft cough, tiring fast on walks around the neighborhood, weight loss or a swollen belly. Don't wait for those signs. By the time they show up, the worms have been there for months.

Some dogs also test positive for a tick-borne disease on the same screen. The vet will explain what that result means and whether your dog needs treatment or just a recheck.

Traveling with your dog

Many dogs in this area are visitors staying near the parks. Walt Disney World's dog-friendly resorts require dogs to be properly vaccinated, and its Best Friends Pet Care asks for proof from your vet. A heartworm test isn't part of that list, but a trip is a good time to get your dog's yearly checks done. Learn about heartworm prevention in Lake Buena Vista.

Heartworm test pricing

The test is often done at a wellness exam, which starts at $99. You'll know the cost of the test before the blood is drawn. PetfolkCare membership starts at $199 a year.

When a cough can't wait

A heartworm test is not urgent, but some signs are. Go to a 24-hour emergency hospital if your dog collapses, has trouble breathing, or has pale gums. The Veterinary Emergency Clinic of Central Florida runs a 24-hour hospital in Oakland.
