Heartworm disease is a serious, potentially fatal condition that affects both dogs and cats. Spread by mosquitoes, it’s especially common in warm, humid climates—making it a real concern for pet owners in Cape Girardeau, Jackson, Perryville, and throughout Cape County. Fortunately, heartworm is preventable, and early treatment can make a big difference.
How Heartworm is Spread
Heartworms are transmitted when a mosquito carrying microscopic larvae bites your pet. These larvae enter the bloodstream and grow into long, spaghetti-like worms that live in the heart, lungs, and surrounding blood vessels. The damage they cause can lead to lung disease, heart failure, and severe health complications.
Why Prevention is Key
Preventing heartworm is much easier—and more affordable—than treating an active infection. Monthly medications prescribed by your veterinarian are effective at stopping the disease before it starts. Even indoor pets are at risk, since mosquitoes can easily find their way inside.
How Heartworm is Treated
If your pet tests positive for heartworm, treatment is possible but more intensive. Your veterinarian may recommend a series of injections and strict activity restrictions to reduce the risk of complications. The process can take several months and may require additional supportive care.
Signs Your Pet May Have Heartworm
Because symptoms often don’t appear right away, regular testing is important. Still, here are some signs to watch for:
-
Persistent cough
-
Fatigue after mild activity
-
Loss of appetite
-
Weight loss
-
Labored breathing
