Heartworms can be a serious problem for pets. These parasites live in the heart, lungs and blood vessels of infected animals, and can cause major complications. Now, that might sound scary, but heartworm disease can be treated and there are ways to prevent it from ever happening in the first place.

We teamed up with Dr. Anvita Bawa, regional medical director with Midwest Veterinary Partners in Royal Oak, Michigan, to answer your questions about heartworms in dogs and cats, including how pets get heartworm disease, what the signs are and whether humans can get it.


How do dogs get heartworm?

A: Dogs get heartworm disease from mosquitoes.


What are early signs that my dog has heartworms?
