**ALL DOGS SHOULD BE TESTED AND ON A HEARTWORM PREVENTIVE**
Canine heartworm disease is transmitted by mosquito bites. Once injected into the dog by the mosquito, immature heartworms migrate to the heart, enter the lungs' blood vessels, become adults, and produce babies (microfilaria) which circulate until they are picked up by a mosquito to infect another dog. The adults that live in the heart and blood vessels of the lungs can survive for years, and cause severe damage. Untreated, they usually kill the dog.
Since treatment is costly and difficult, it is best to use a monthly prescription heartworm preventive, such Heartgard Plus. Bi-annual heartworm testing is strongly recommended. In this climate, heartworm protection is necessary every month throughout the dog's life.
Thankfully, testing for Heartworm is easy and only requires a small amount of blood. Larkfield Veterinary Hospital offers the 4Dx Snap Heartworm test, which tests not only for heartworms but for the three most common tick-borne diseases as well.
