I have a husky names Rusty, Do you have any dogs?
I have three!  A rat terrier, a boston terrier and a small mix.  Huskies are so pretty though - they are the fastest dogs.
i did not know that but it makes sense
It's one of the ways they differentiate them from other sled-dog types by their fast pulling style
I would never want my dog to do that lol. do they compete in it like a sport sled racing?
Husky
Husky is a general name for a sled-type of dog used in northern regions, differentiated from other sled-dog types by their fast pulling style. They are an ever-changing cross-breed of the fastest dogs. The Alaskan Malamute, by contrast, was used for pulling heavier loads. Huskies are used in sled dog racing. In recent years, companies have been marketing tourist treks with dog sledges for adventure travelers in snow regions as well. Huskies are also today kept as pets, and groups
indoor breed. It is important they are kept busy and social to discourage boredom. In a recent survey reported (on Dogs 101) of 91 small breed dogs (16 inches and under 22 lbs) the Silky Terrier was ranked in the top 20 in learning the quickest.
The Silky Terrier is described as the best of both worlds temperament-wise . They love to sit on laps and do "toy dog" things but have an easy going more laid back Terrier personality ready for just about any activity.
