Is heartworm common in Alberta?

0

Heartworm is transmitted by mosquitos and is dependent on their life-cycle as well as the weather. In order for the heartworm to manifest into an infectious state, it requires a certain number of consecutive days of warm weather. In Alberta, the cold weather interrupts the mosquito’s life cycle and often times the weather is not consistant enough for the worm to develop. In 2006 there were no reported resident dogs (dogs that did not leave the province) diagnosed with heartworm in Alberta. However, with the changing weather patterns many owner’s have started their pets on a prevention program of heartworm. Anyone travelling outside Alberta with their pet should consult a veterinarian as to the risk and alternatives for prevention.
