Heartworm disease is a serious threat to our furry family members. Caused by parasitic worms that lodge themselves in the heart and lungs, it can lead to coughing, fatigue, and even death if left untreated. While preventive medication is widely available, there are some concerns that heartworm disease might be on the rise in the United States.

Is it really getting worse?

There isn't a definitive answer yet. Veterinarians haven't reported a widespread surge in cases. However, some factors could potentially contribute to an increase in heartworm infections:

  • Travel: More people are taking their pets on adventures across state lines. This exposes them to mosquitos in areas with higher heartworm prevalence.
  • Relaxed prevention habits: Not all pet owners prioritize preventive medication. Some might forget to administer it or discontinue it altogether, especially if their pet lives primarily in the house.
  • Population increase in Idaho: As people move to the Gem state, they are bringing their beloved pets and an increase in heartworm cases, according to the 2022 American Heartworm Incidence Map

Spotting Heartworm Early: What to Look for in Your Dog

Mosquitos spread heartworm. The good news is that heartworm disease is treatable with prevention and early detection. But how do you know if your dog might have heartworm?

Here's a rundown of the common symptoms to watch for:

  • A Persistent Cough: A dry, hacking cough that just won't quit is a hallmark sign of advanced heartworm disease. This cough is caused by the worms irritating the lungs.
  • Exercise Intolerance: Does your playful pup suddenly seem pooped after a short walk? This fatigue can be a sign that their heart and lungs aren't working as efficiently due to heartworms.
  • Weight Loss: If your dog is losing weight despite having a normal appetite, it could be a red flag for heartworm.
  • Other Signs: As heartworm progresses, other symptoms may appear, including lethargy, swollen belly, and difficulty breathing. In severe cases, a dog might experience Caval syndrome (CS), a sudden and life-threatening blockage caused by a mass of heartworms.

It's important to remember that not all dogs with heartworm will show symptoms, especially in the early stages. That's why routine veterinary checkups and preventive medication are crucial.

If you notice any of these signs in your dog, schedule an appointment with your vet right away. Early diagnosis and treatment can significantly improve a dog's prognosis.

What can we do and how to protect your pet?

  • Year-round prevention: Talk to your veterinarian about the best heartworm prevention medication for your dog (and cat, in some cases!). Don't skip doses, even during winter.
  • Mosquito control: Eliminate standing water around your house where mosquitos can breed. Consider using pet-safe mosquito repellents.
  • Stay informed: Regular vet checkups can detect heartworm early, making treatment easier.

By being aware of the symptoms and taking preventive measures, you can help your dog stay happy and healthy for years to come.
