Unfortunately, even with treatment, the damage caused by these worms to the heart, lungs and other organs is irreversible and can affect your pet for the rest of their life. The good news is, the preventatives we stock, such as Advantage Multi, and Interceptor Plus are very effective at reducing this risk and preventing heartworm disease. As a bonus, they can help protect your pets against parasites that live in their intestines. Please reach out to us to schedule an appointment to have your pet tested and get them started on a life-saving preventative.
