What kind of habitat do Alaskan huskies live in?

I have 7 Huskies, 2 Adult, And 5 Puppies, I have a extremely large Fenced in Backyard, When they are in the house the Puppies are in crates for House Breaking, And my Adults are free to roam the house, When they have to use the bathroom they sit near the door, And Bark (Howl) to let me know, On trips they come with or are provided with a sitter, Huskies require plenty of excercise and are not good for Apartments, They have a Moderate to Heavy step and can annoy other tenants below.
