What is Heartworm Disease?

Dogs are naturally susceptible to heartworm disease. Heartworm disease is an illness that can result in heart and respiratory conditions in dogs. It is initiated by a parasite that is referred to as a heartworm. Heartworm gets into the dog’s blood vessels and eventually makes its way into their heart where the worms start to grow.

These worms live in the heart and lungs and can grow up to a foot long. As the worms mature, they mate and create offspring. The offspring also grow building up blockages in the heart and lungs as they multiple.

Heartworm infections left untreated can trigger severe heart and lung problems and damage other organs in the body. In addition, the worms can weaken the immune system, cause anemia, and even blood clots after the worms are gone. It can possibly be fatal if it is not treated early enough. This disease can be prevented with prophylactic medications.

Dogs are naturally susceptible to heartworm disease. Heartworms can live inside the dog and live there long enough to mature into adult worms.

Heartworm disease can affect dogs, cats, and ferrets. In rare cases, humans can also be carriers of the disease. Prevention is the most practical solution, and treatment should be given as early in the disease process as possible.

How Does a Dog Get Heartworm?

Dogs get heartworms from mosquitoes. An infected dog cannot spread heartworm disease to another dog, as it is not contagious.

When a mosquito punctures an infected dog, it drinks the dog’s blood as well as some microscopic heartworm larvae. The larvae are only millimeters in length at this point. While inside the mosquito, the larvae begin growing and maturing. Then, the mosquitos bites an uninfected dog and transmits the mature larvae into the dog’s tissues through the bite.

This process is how a dog contracts heartworm disease. They travel through the mosquito’s bite into the dog’s tissues.

After the larvae are in the dog’s tissue, they perform a complex migration pattern on the dog’s body as the worm continues growing and becomes an adult. The parasites go through the dog’s system and situate themselves within the pulmonary artery.

This time is when they grow into larger worms, mate, and have babies; thus, perpetuating the vicious cycle.

What Are the Indicators of Heartworms in Dogs?

Knowing what symptoms to look for in your dog when it comes to heartworm can be tricky. Sometimes dogs do not show any signs at all. It depends on how progressed the disease is in your pup. The following are some of the symptoms your dog can have if they have heartworm:

  • Coughing
  • Coughing up blood
  • Increased respiratory rate
  • Decreased energy
  • Abdominal swelling
  • Running out of breath when exercising
  • Heart failure
  • Liver damage
  • Internal inflammation
  • Increased blood pressure
  • Kidney damage
  • Blood clots

The severity of the clinical signs linked with heartworm disease depends on how many worms reside in your pup and how long the parasite has lived in their system. If you suspect your dog could have heartworm, do not hesitate to get them to the vet.
