 This worm lives in the heart and/or lungs of dogs and cats and is transmitted by mosquitoes. An adult worm can measure as long as 16 inches in length.

"Heartworms are parasites that live in the blood of an infected dogs’ heart and surrounding blood vessels. They are transmitted to the dog (host) by the bite of an infected mosquito. The adult worms live in the heart of the host and produce offspring (microscopic larvae) called microfilariae. These small larvae circulate in the dogs’ blood. When a mosquito bites the dog, it ingests blood containing microfilariae which are then passed on to the next dog that the mosquito bites.

These nasty little creatures can cause serious problems for dogs by enlarging the heart, restricting blood flow and damaging internal organs. It can usually be treated with drugs, but the best way to treat heartworm is with prevention. Talk to your veterinarian about treatments prior to traveling to a mosquito infested area.

 

The high risk areas for heartworm in Canada are southern Quebec, southern Ontario, Manitoba and the Okanagan area in British Columbia. There are very few reported cases in Alberta and Saskatchewan, but prevention is still the best cure, even in those provinces."  http://www.doghikingcanada.com/heartworm.html
