He looks around 8 weeks. At that age, they can't really hold it for more than a couple of hours. The general rule is 1 hr for each month in age. You'll be getting up at night a lot for the first few month for potty breaks but don't worry- he'll start sleeping through the night soon.
I wouldn't allow him to use a doggy door at this age- too many dangerous things he can chew on plus you want to see when he goes so you get "get excited" and praise him for a good job. No scolding for when he goes in the house..just clean it up and keep going. Just praise good behaviors.
Puppy proof your house to the best of your ability and monitor him 24/7 when he's not in his safe "puppy area". Electric wires, shoes, anything you don't want chewed has to be put up for a while.
Tip of in the future..when he start teething. Grannick's bitter apple spray from petco, petsmart, etc. Spray on whatever he shows interest in that he's not suppose to chew on (wall, furniture...whatever). Worked wonders with our Nyla.
Also, a good quality food (Taste of the Wild, Blue Buffalo, Blue wilderness,etc) will keep him in top shape and prevent a lot of problems such as shedding, weight gain..etc.
I know you probably know this already, but read as much as possible about huskies. They are AWESOME dogs but very...special. LOL
Keep us updated with pics please!
Oh and if you're interested to see a comparison- here is Nyla and her brothers at 8 weeks old. http://www.asecondchancerescue.org/a...imalID=5022768
