Sounds just like any young husky. Basically, it's training, training, training. And then more training.

Keep in mind that a husky pulling as hard as he can is a husky doing exactly what he was bred to do. Pulling is his job. You can't fight centuries of breeding. Expecting a husky to trot along side of you is simply not his nature. His nature is to pull whatever he's attached to, whether it's you or a sled.

But keep it fun, he's young & huskies tend to be pretty lively their first few years. If it isn't fun, he won't cooperate. Huskies are also quite stubborn.

He may not be getting enough exercise. If huskies are under-exercised, they can be a real handful, especially at the end of a leash. (Mine are really good at becoming "air-borne" on the end of a leash if I've skipped a walk.) Does he have somewhere fenced where he can run as fast as he can? If not, that will mean a lot of extra walking with you. Several husky owners I know use a Springer, an attachment for your bike that allows the dog to safely run alongside.

I've always found that playing chase or ball in a yard is good too. (Star would fetch for hours when she was that age.) And the good news is that huskies do mellow with age. Walking a mature husky is not at all like walking a juvenile. Give him a few years.

You might try using a gentle leader, sometimes that will help, I used one with my rottie-mix girl & the effect was instant. Walking her was like trying to walk a tank, I got dragged along. With the gentle leader, she walked with a slack leash. I was amazed.
