Heartworm Prevention in Vintage Park, Houston, TX, From Your Local Vet

Petfolk Veterinary & Urgent Care - Vintage Park is a vet in Vintage Park, Houston, that prescribes heartworm prevention for dogs and cats. In this part of Texas, every dog and cat should be on it every month of the year.

Heartworms are long worms that live in the heart and lungs. They spread through a single mosquito bite. Prevention is a monthly chew, topical or a long-lasting injection. Treatment, once a dog is infected, takes months and is far harder on the dog.

Call (346) 658-0421 or book online. Walk-ins are welcome, and the clinic is open weekends.

Does my pet need heartworm prevention all year in Houston?

Yes. Texas ranks first in the nation for heartworm cases in the American Heartworm Society's latest incidence survey, based on 2025 testing data. Houston winters are short and mild, and a few warm days are enough for mosquitoes to bite again. Skipping the "cold" months leaves a gap that heartworms can use.

Texas A&M's diagnostic lab also notes that heavy rain boosts mosquito numbers. After a storm in northwest Houston, that risk climbs even higher.

Chews, topicals or a yearly shot

The vet at Petfolk Vintage Park helps you choose the product that fits your pet and your routine:

• Monthly chewables for dogs: many also cover fleas, ticks and some intestinal worms in one dose.

• Monthly topicals for cats: a few drops on the back of the neck, often covering fleas and ear mites too.

• Long-lasting injections for dogs: given by the vet, so there is no monthly dose to remember. Across Petfolk, about 6% of dog prevention purchases were ProHeart 12, a yearly injection.

Across Petfolk's Houston-area clinics, about 9 in 10 dog parasite-prevention purchases were Simparica Trio, a monthly chew for heartworms, fleas and ticks, from October 2025 through September 2026. That doesn't mean it's right for every dog. The vet considers weight, age and health first.

They both explain the diagnosis very throughly and offer various pricing differences with prescriptions.

Do cats need heartworm prevention too?

Yes. Cats can get heartworm, and there is no approved treatment for it in cats, so prevention is the only protection. Indoor cats still get bitten by mosquitoes that slip inside. Across Petfolk's Houston-area clinics, about 4 in 10 wellness visits for adult cats sent parasite prevention home in that same window.

Does my dog need a test before starting?

Yes. Dogs older than about 7 months should have a heartworm test before starting or restarting prevention, and then once a year. Giving prevention to a dog that already has heartworms can cause a reaction, so the test comes first. See heartworm testing in Vintage Park.

Older dogs still need it

Prevention often slips as dogs age. Across Petfolk's Houston-area clinics, fewer than 3 in 10 wellness visits for dogs 7 and older sent heartworm, flea and tick prevention home. Senior dogs are just as exposed to mosquitoes, and a heartworm infection is harder on an older heart.

What does heartworm prevention cost?

The price depends on your pet's weight and the product. Prevention is often started at a wellness exam, which starts at $99 at Petfolk Vintage Park. You'll get an estimate before any test or treatment. The final bill can differ if the plan changes during the visit.

Fear Free handling is standard at every Petfolk clinic, including the quick blood draw for the heartworm test.

When to call

If your dog coughs, tires easily on walks or breathes fast at rest, book a visit. Collapse, a swollen belly or trouble breathing needs a 24-hour emergency hospital such as BluePearl Pet Hospital on Spring Cypress Rd in Spring.
