I would definitely crate of a night as a puppy.
Mine are both quite happy in their crates, they see at as their 'den' and know its bed time when they go in there.
I have been a bit naughty lately and let them out on the bed with us... you wouldn't think 2 small dogs could take up so much room :rolleyes:
It's up to you whether you let her sleep on the bed with you when she's older, but for now, until potty training is finished I would be crating.
Challenging toys for a husky would be kongs or other similar 'puzzle' toys. Peanut butter is a good filling.
Squeekys are always a favourite, mine will quite happily sit there and squeek away for ages, throwing the toy around.
