Heartworm 101: What You Need to Know to Protect Your Dog
Heartworm disease is a serious and potentially fatal condition that affects dogs all across the United States. Spread by mosquitoes, heartworms are parasitic worms that live in a dog’s heart, lungs, and blood vessels, causing severe health issues.
The good news is that heartworm disease is preventable! Here’s what every dog owner needs to know.
How Dogs Get Heartworms
When an infected mosquito bites a dog, it transmits microscopic heartworm larvae into the bloodstream. Over the course of several months, these larvae mature into foot-long adult worms that can cause lung disease, heart failure, and organ damage.
Mosquitos are present in all 50 states, making heartworm a risk nation-wide, especially in warmer climates.
Signs of Heartworm Disease
In the early stages, dogs may not show any symptoms. As the disease progresses, common signs include:
-
Persistent cough
-
Fatigue after mild activity
-
Weight loss
-
Difficulty breathing
-
Swollen abdomen (due to heart failure)
-
Severe cases can lead to life-threatening complications, making early detection crucial.
How to Protect Your Dog from Heartworm Disease
The best way to protect your dog from heartworms is with a veterinarian-prescribed preventive medication.These medications work by killing immature larvae before they can develop into adult worms.
Options include monthly chewables, topical treatments, and injections given every six or 12 months. No matter what type of preventative you opt for, it’s important to stick to a regular schedule to keep your pup protected.
Pro tip: If you love taking your dog on outdoor adventures, be extra cautious in mosquito-heavy areas like lakes, forests, and parks. Packing a well-stocked pet first aid kit can help you be prepared for any unexpected scrapes, bug bites, or allergic reactions while on the go.
Even if your dog is on preventive medication, it’s still important to have your dog annually tested for heartworm at your vet. No prevention method is 100% foolproof, and early detection can make treatment more manageable if an infection occurs.
Keep Your Dog Healthy and Heartworm-Free
By keeping your dog on year-round heartworm prevention and scheduling regular vet visits, you can ensure they stay safe, happy, and ready for more adventures with you for years to come. Protecting your pup from heartworms is easy—and it could save their life.
