Heartworm disease is a serious and potentially fatal condition—especially for dogs in the Southeast, where mosquitoes are active for much of the year. Prevention is simple, but treatment is expensive and risky.

At Southcentral Veterinary Services, we emphasize year-round prevention as the best way to protect your pet.

What Is Heartworm Disease?

Heartworm disease is caused by Dirofilaria immitis, a parasitic worm spread by mosquitoes. Once bitten, your pet can become a host to heartworm larvae, which migrate through the body and settle in the heart, lungs, and blood vessels.

If left untreated, heartworms can grow up to 12 inches long and lead to:

• Heart failure

• Lung disease

• Organ damage

• Death in severe cases

Which Pets Are at Risk?

• Dogs are the primary host and most at risk

• Cats can also contract heartworms, though they often have fewer worms and different symptoms

• Even indoor pets are vulnerable if a mosquito gets inside

Signs of Heartworm Disease

In dogs:

• Coughing

• Fatigue

• Labored breathing

• Weight loss

• Swollen abdomen (due to fluid buildup)

In cats:

• Vomiting

• Gagging

• Asthma-like symptoms

• Sudden collapse or death

Prevention Is Key

There are several safe, effective options:

• Monthly oral or topical preventives

• 6- or 12-month injectable preventives (for dogs)

• Annual heartworm tests to ensure your pet stays protected

Prevention costs a few dollars a month—treatment can cost thousands and poses serious risks to your pet.
