I've got two dogs, and before we got the first I did extensive research on the breed, read books, articles, etc etc.....
And still it hit me like a hammer, huskys are not normal dogs !! None of the books told me that, no one warned me !. They are stubborn, determined, cantankerous fur machines, and I wouldn't change mine for all the world.
As for the food allergies, have you thought about raw feeding ? My boy was a hypermaniac on dry food, almost constant zoomies, never settling, I joined this forum, got some advice and switched to raw and the change was drastic, literally 3 days and he calmed down (well, calmed down to normal husky levels !) it might be worth discussing with your vet
