Veterinarians across the U.S. dedicate April as the month to raise awareness of the importance of Heartworm prevention. Although Santa Clarita is a low-risk area for Heartworm Disease, we have diagnosed dogs with heartworm at our veterinary center.

What is Heartworm Disease?

Heartworm is a disease of worms that invade the heart of an animal. Pets are infected through the bite of a mosquito. Once your pet is infected, worms begin to grow inside your pet’s body and can inhabit their heart, lungs, and blood vessels.

The Heartworm Life Cycle

Adult female heartworms living in an infected dog, fox, coyote, or wolf produce microscopic baby worms called microfilaria that circulate in the bloodstream.

When a mosquito bites and takes a blood meal from an infected animal, it picks up these baby worms, which develop and mature into “infective stage” larvae over 10-14 days. Then, when the infected mosquito bites another dog, cat, or susceptible wild animal, the infective larvae are deposited onto the surface of the animal’s skin and enter the new host through the mosquito’s bite wound.

Once inside a new host, it takes approximately 4-5 months for the larvae to mature into adult heartworms. Once mature, heartworms can live for 5-7 years in dogs and 2-3 years in cats. Because of the longevity of these worms, each mosquito season can lead to an increasing number of worms in an infected pet.

What are the Symptoms of Heartworm?

A pet can have heartworm without initially showing symptoms. The signs of heartworm disease depend on the number of adult worms present, the location of the worms, the length of time the worms have been in the pet, and the degree of damage that the heart, lungs, liver, and kidneys have suffered.

Most pets initially infected with heartworm do not show symptoms until the disease is more advanced. Following are symptoms to watch out for that could indicate your pet has heartworm:

  • Occasional or persistent coughing: As the heartworm , your pet’s cough will become more frequent.
  • Trouble breathing: As the disease progresses, breathing may become more and more labored.
  • Tiring quickly: With blood flow being blocked or partially blocked, your pet will become tired much more rapidly.

If you notice any of the above symptoms, whether it could be heartworm or not, bring your pet in for a checkup.

Treatment of Heartworm

Another reason preventing heartworm is so essential is that the treatment for a heartworm infestation is unpleasant and comes with significant risks for your pet. However, we can successfully treat most infected pets.

After stabilizing your pet’s condition, treatment takes several steps and may require your pet to stay in our care so that we can carefully monitor them. The complete process takes several months because we must destroy heartworms gradually. Killing them too quickly can be dangerous for your pet. Due to the length and complexity of treatment, treatment can become expensive. Preventing heartworm disease is much less costly than treating it.

How to Prevent Heartworm

Understanding Heartworm is the first step in prevention. Next is understanding what you can do to help keep your pet safe and healthy.

Routine veterinarian visits and heartworm testing: Schedule your pet for their annual checkup and heartworm testing with us to ensure your pet stays healthy.

Preventative medication: There are various preventative products that you can use on your dog to ward off mosquitoes and prevent heartworm. You can administer these products orally or topically. The combination of a heartworm preventive paired with an effective flea, tick, and mosquito repellent is most effective for preventing disease. Prevention is far more effective and less costly than treatment if your pet is diagnosed with heartworm. Heartworm medications are available only by prescription, and there are different options depending on your pet and your preferences. Talk to us about which heartworm medication is right for your pet.

Keep your home mosquito-free: Mosquitoes can also be a threat in and around your own home. Mosquitoes can breed in small amounts of stagnant water. Check out flowerpots, empty containers left outside (buckets, toys), rain gutters, and low-lying areas in the yard. Please do your best to remove any stagnant water around your house to minimize their numbers.

Outdoor bug control: Minimizing bugs in your yard is very important in helping to keep bugs away from your pet. You may want to consider using insecticide spray for your yard. Be sure to choose a pet-friendly product and properly follow the manufacturer’s instructions.

Summary

Heartworm is a potentially fatal disease, and it is hard to detect in its early stages. Treatment is difficult for pets and comes with significant risks. It’s vital to keep pets on heartworm prevention because it’s impossible to prevent mosquitoes from biting your pet. This recommendation also applies to indoor pets because mosquitoes can get inside the house, putting indoor-only animals at risk of contracting the disease.

Prevention is easy, inexpensive, and pain-free. So, please keep your pets safe and healthy by contacting us and getting your pet on heartworm preventative medication if you have not already done so.
