Heartworms: What Every Pet Owner Needs to Know

It is estimated that more than 1 million dogs are infected with heartworm in the United States each year.

Heartworm disease is a serious and potentially life-threatening condition that affects dogs and cats. Mosquitoes are the only way for heartworm larvae to spread from one pet to another, so controlling their population can help to prevent the spread of this dangerous disease. In rare cases, humans can get heartworms after being bitten by an infected mosquito.

Common symptoms of heartworm disease in dogs include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and weight loss. In severe cases, pets may experience fainting, difficulty breathing, and an enlarged abdomen due to excess fluid.

When an infected mosquito bites your pet, it transmits the larvae, which then travel through the bloodstream and lodge in the heart and lungs. Over time, these larvae can cause severe damage to your pet's organs and can even be fatal. Fortunately, there are ways to protect your pet from heartworm disease. Regular preventive medications are available that can kill any larvae before they have a chance to do damage. Additionally, mosquito control is an important part of prevention. Reducing the number of mosquitoes in your area can help to reduce the chances of your pet becoming infected.
