How do dogs get heartworms?

Understanding How Dogs Get Heartworms

Dogs get heartworms through the bite of an infected mosquito. When a mosquito bites a dog, it can transmit heartworm larvae (microfilariae) into the dog's bloodstream. These larvae then mature into adult heartworms, which can live in the dog's heart and lungs, causing serious health issues. It's crucial for dog owners to understand that heartworms are not contagious between dogs; they can only be spread through mosquitoes. To prevent heartworm disease, regular veterinary check-ups and preventive medications are essential, especially in areas where mosquitoes are prevalent. Additionally, keeping your dog away from standing water and ensuring they are on heartworm prevention medication can significantly reduce the risk of infection.
