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?
yes Huskies are actually used in sled dog racing!
