Heartworm disease is a serious and potentially fatal condition that affects dogs, cats, and other animals. It is caused by a parasite that is transmitted by mosquitoes and can cause damage to the heart, lungs, and other organs. Here are some key facts about heartworm disease in pets:


Heartworm disease is transmitted by mosquitoes that carry the parasite. When an infected mosquito bites an animal, it can transmit the parasite into their bloodstream.


The best way to prevent heartworm disease is to give your pet a monthly preventative medication. These medications are available as pills, topical treatments, or injections and are highly effective at preventing heartworm disease.


Pets should be tested for heartworm disease annually. This involves a simple blood test that can detect the presence of the parasite in the bloodstream.


Symptoms of heartworm disease in pets can vary, but may include coughing, difficulty breathing, fatigue, weight loss, and a decreased appetite.


If your pet is diagnosed with heartworm disease, treatment is available. However, it can be expensive and may require hospitalization. It’s important to treat heartworm disease as soon as possible to minimize the damage to your pet’s organs.

Prevention for cats

While heartworm disease is more commonly associated with dogs, it can also affect cats. There is no treatment for heartworm disease in cats, so prevention is especially important.

Transmission risk

Mosquitoes are the primary vector for heartworm disease, and warmer climates with higher mosquito populations have a higher risk of transmission. However, heartworm disease has been reported in all 50 states of the US.

Heartworm disease is a serious and potentially life-threatening condition that can affect pets of all ages and breeds. By giving your pet a monthly preventative medication, having them tested annually, and monitoring for symptoms, you can help to protect them from heartworm disease. Talk to your veterinarian for more information about heartworm disease prevention and treatment for your pets.
