Of all the worms that can affect a household pet, heartworms are the most problematic. Unfortunately, they are easy to contract, but difficult to get rid of. Once transmitted they can cause serious health issues for both dogs and cats and can be costly and often dangerous to treat.

Heartworms differ from intestinal worms not only in the parts of the body they affect but in the ways they are transmitted, prevented and treated. All pet owners should be aware of the specific risks, medications, and symptoms that are associated with heartworm disease.
