Hey, so I have a husky that we use as a sled dog up north. have you ever seen one?
Yes.  Aren't they really big and have thick fur?
Yes! Although there are many types of huskies. The breed ever-changing due to cross breeding. what type did you see?
I am not sure.  I do not know much about them.  They are beautiful animals!
I have an Alaskan Malamute. They the biggest and strongest sled dog. He can carry at least a few people easily! Have you ever been pulled by dogsled? 
I have not but would love the experience.  How heavy does an Alaskan Malamute get?
Gee I am not sure exactly, but he's big! They're used for heavy hauling because he has so much endurance. 
Are those the same kind of huskies that are used in the long distance dog sled races?
Yes exactly! Many different husky breeds are used for sled racing though. You should try it some time!
