Heartworm disease is a serious but preventable condition that can affect both dogs and cats. Transmitted by mosquitoes, these parasites can cause severe heart and lung damage, leading to life-threatening complications.

Dogs are natural hosts for heartworms, meaning the parasites can fully mature and reproduce inside their bodies. Once infected, dogs can suffer lasting heart and lung damage, making early detection and preventative medication essential.

Cats, on the other hand, are not natural hosts, so heartworms often fail to reach adulthood. However, even immature worms can cause severe respiratory issues, including Heartworm-Associated Respiratory Disease (HARD). Unfortunately, there is no approved treatment for heartworm disease in cats, making prevention the only way to protect them.
