Heartworm Testing in Mansfield, TX, From Your Local Vet

Petfolk Veterinary & Urgent Care - Mansfield is a vet in Mansfield, TX, that tests dogs for heartworm with a quick blood test run in the clinic's own lab. Most dogs need one test a year, even when they take prevention every month. Results often come back during the visit, so you leave with an answer and a refill.

Call (817) 241-2355 or book online. The test fits into a wellness visit.

Why test a dog who's already on prevention?

No preventive is perfect, and life gets busy. A dose spit out in the yard, a month skipped during a move, or a chewable given a week late can leave a gap. Testing every year catches an infection early, when treatment is simpler. It also tells the vet whether your current product and your monthly routine are working, or whether something needs to change before next summer's mosquitoes arrive. Texas ranked first in the nation for heartworm in the American Heartworm Society's survey of 2025 testing data, so a missed dose here carries real risk.

Which test does Petfolk Mansfield use?

The standard in-house test looks for heartworm and common tick-borne diseases in one small blood sample. That matters in North Texas, where Texas A&M AgriLife reports ticks are active all year. The brown dog tick can live indoors and spread canine ehrlichiosis, one of the infections the test screens for.

Across Petfolk, from October 2025 through September 2026, this heartworm and tick-borne disease test was the single most-ordered in-house lab test. If a result comes back positive, the vet may send a second test to a reference lab to confirm it before any treatment starts.

When should my dog be tested?

• Every year, usually at the wellness visit.

• Before starting prevention in dogs older than about 7 months.

• About 6 months after switching products or after a gap in doses.

• When signs show up, like a cough, tiring on walks or weight loss.

Puppies under about 7 months start prevention without a test, since an infection wouldn't show up yet.

If your dog is new to Mansfield, test at the first visit unless you have a negative result from the past year on paper. Families who moved from cooler, drier states are often surprised by how many mosquitoes a North Texas summer brings. A clean test now gives you a starting point for every year after.

What if the test is positive?

Take a breath. Heartworm disease in dogs is treatable, especially when caught early. The vet will confirm the result, check how your dog's heart and lungs are doing, and explain the plan. Treatment usually means several months of strict rest, so your dog's heart isn't strained while the worms die off. Your vet will talk through whether your dog is treated at the clinic or referred, and what it will cost before you decide.

Testing cats is different

Cats are tested differently, and the tests are harder to read. Many cats with heartworm test negative. For cats, the vet looks at signs, history and sometimes x-rays, and focuses on year-round prevention. See heartworm prevention in Mansfield for cat options.

Test cost and the visit

The blood draw takes about a minute. Fear Free, gentle handling and treats help nervous dogs. You'll get an estimate before any test or treatment. The final bill can differ if the plan changes during the visit. A wellness exam at Petfolk Mansfield starts at $99, and PetfolkCare membership starts at $199 a year.

If your dog shows serious signs

A dog who collapses, coughs up blood or breathes very fast at rest needs help right away. Go to a 24-hour emergency hospital such as Thrive Pet Healthcare Specialists at 301 U.S. 287 Frontage Rd.
