Mouthing and biting at that age is common place with most breeds of dogs but Huskies do indeed tend to have a higher tendency to do it.
Check out the sticky in the training forum on how a lot of members have worked through this behaviour in the past.
Puppy BitingThere are also a number of topics in the forum as well pertaining to people going through the same issues. Your not alone in the matter.
It sadly however isn't an overnight fix and there is no one right way to go about curving the behaviour.
You need to find what works for both of you and something that gets through to him.
Just saying Ow normally won't be enough. Either removing him, yourself, or stopping all play and the ability to continue to play so he understands when you say Ow play is stopping. After a couple of times he should start to put it together.

really anything can and will work... It's all about remaining firm and consistent. Define your rules and stand by them. With enough time and work he will begin to get it.
