Heartworm Disease – Testing and Prevention

We provide services to prevent, diagnose and treat heartworm infection.

Heartworm is a large parasitic worm of the roundworm family that thrives in a dog’s heart. It feeds on the nutrients in the blood stream and can grow to a length of 15-30 centimeters. In severe cases, up to 500 worms may infect a dog. If left untreated, heartworm can permanently disable your pet or eventually kill it.

Mosquitoes transmit heartworm infection. A dog or wild animal infected with heartworm serves as a reservoir, mosquitoes feed on these animals and then transmit the infective larvae to other dogs in subsequent blood meals.


• There are a number of highly effective and convenient preventative medications available. Please consult with us for more information as to which preventative is best suited for your pet’s needs.


• We recommend that all dogs that have been on a preventative be tested for heartworm infection every two years. This is to ensure that the medication is doing its job protecting your pet from heartworm infection.
