Heartworm Prevention in Noblesville, IN, From Your Local Vet

Petfolk Veterinary & Urgent Care - Noblesville is a vet in Noblesville, IN, that prescribes heartworm prevention for dogs and cats. Heartworms are long worms that live in the heart and lungs. They spread through mosquito bites, and one bite from an infected mosquito is enough.

Prevention is a monthly chew, a monthly topical, or an injection that lasts up to a year. Treating an infection is much harder, longer and costlier than preventing it.

Call (463) 217-5944, book online or walk in to start or refill prevention.

Does my pet need heartworm prevention all year?

Yes, at Petfolk Noblesville the vet recommends year-round prevention for most dogs and many cats. Indiana winters slow mosquitoes but do not end them on every warm stretch, and a missed spring or fall dose leaves a gap. Year-round dosing is also easier to remember: same day, every month, no restart date to track.

The medicine works backward. A monthly dose clears young larvae your pet picked up in the past month, before they grow into adult worms. That is why a late dose matters, and why the vet asks about gaps.

Which prevention is best for my dog?

At Petfolk Noblesville, the vet helps you choose based on your dog's habits and your routine:

• Monthly chewable. Many combine heartworm prevention with flea and tick protection and intestinal worm control in one treat-like chew. Across Petfolk, 85% of dog parasite-prevention purchases are Simparica Trio, a monthly chew that does all three (Oct 1, 2025 to Sep 30, 2026).

• Yearly or 6-month injection. ProHeart is given at the clinic, so there is nothing to remember at home. It covers heartworms only, so your dog still needs flea and tick protection. About 6% of Petfolk dog prevention purchases are ProHeart 12.

• Monthly topical. A liquid applied to the skin, useful for dogs who will not take chews.

Dogs who swim at Morse Park & Beach or splash in the White River along the Forest Park Trail often do better with a chew, since some topicals wash off.

Do cats need heartworm prevention?

Yes. Cats are not the natural host, so they usually carry only a few worms, but even one or two can cause serious lung disease, and there is no approved treatment for cats. Indoor cats are at risk, since mosquitoes get inside. At Petfolk Noblesville the vet often suggests a monthly topical. Across Petfolk, 88% of cat prevention purchases are Revolution Plus, which also covers fleas, ticks, ear mites and some intestinal worms.

A test comes first

Most dogs over 7 months old need a negative heartworm test before starting or restarting prevention. Giving prevention to a dog that already has adult worms can cause a reaction, and the test also shows whether last year's plan worked. Puppies under 7 months can usually start without a test, then get tested later.

Fear Free handling is used for the quick blood draw. Results from the in-house lab often come back during the visit.

Prevention costs

Prevention is prescribed after an exam. Wellness exams start at $99 at Petfolk Noblesville, or are included with PetfolkCare, which starts at $199 a year. Each product is priced by your pet's weight. You'll get an estimate before any test or treatment. The final bill can differ if the plan changes during the visit.

Missed a dose?

Give the dose as soon as you remember and call the clinic. If more than a couple of months were missed, the vet may suggest a test about 6 months later to make sure nothing slipped through. Coughing, tiring fast on walks or fainting in a dog should be checked soon. For a pet who collapses or cannot breathe, go to a 24-hour emergency hospital such as MedVet Indianapolis on Mayflower Park Dr in Carmel.
