The term Mackenzie River Husky describes several overlapping local populations of arctic and subarcticsleddogtype dogs, none of which constitutes a breed. Most prominent and current of these are the sleddogs of Donna Dowling and others in the interior of Alaska. These dogs are described as standing 26 to 29 inches (66 to 74 cm) in height and weighing 63 to 104 pounds (29 to 47 kg). Usually long-coated, they are rangy, deep-chested and long-legged, built for heavy freighting in single file through deep snow. Their colors are the usual northern-dog range of black and white, shades of grey and sable, tan, blond, and red.
Currently Donna Dowling acts as a coordinator for Alaskan residents interested in breeding and preservation of the native arctic freighting dog. She describes the gene pool as capable of considerable variation, but states that the temperament is always guaranteed to be independent but “completely trustworthy with children, intelligent and eager to work.”
