My favorite dog growing up. Sweet and loving and eager to please.
They are demanding. Like the poster above, ours pulled a ton. Remember, they were bred to pull sleds. If you can give them a half hour to an hour for exercise / running each day and have a pretty spacious yard for them to use, it'll be a great dog.
Also, they shed like mad in the summers. Lose their winter coat. If you brush them frequently it'll be fine, but I wouldn't plan to keep them inside much unless you're willing to put up with the hair.
Again, very sweet, loyal dogs.
