What is heartworm disease?
Heartworms are deadly parasites that are transmitted from dog to dog through mosquito bites. Anywhere mosquitoes are found, dogs are at risk. Heartworm larvae travel through your pet’s blood to the large vessels of the heart. Inside the heart, they move and grow, damaging the delicate tissues of the heart, which can cause heart disease and murmurs.
If the heartworm dies, it will block the vessels, leading to cardiac arrest. It’s essential to protect your pet against heartworm throughout its entire life. If you miss a treatment, your vet may need to order a blood test to check for an infestation.
