A lot of people I've met (I ran a business taking care of dogs) got an idea in their heads about what kind of dog they wanted, then got it, and realised it wasn't the animal they had pictured in their minds.
In my mind - Fester was on the ball with his comment:
If you go to the SPCA you'll probably find exactly what you're looking for. All of our dogs have been strays, and they've been loving, smart, long lived, and devoted pets as we could hope for. I've knoticed many large Husky-lab crosses at the spca over the years, which combines the strength and coat of a husky with the temperment and work ethic and drive to please of a lab. Plus, crossbreeds are often free of all those defects caused by overbreading in purebreeds. Once again - in all my time looking after dogs, it's almost always the purebreeds that get the problems, and when it's your pet, you'll really appreciate the extra years you get to spend together before you part ways or have to put them down.
To reiterate, before you go out and spend $500-$3000 on a puppy, go to the SPCA, or several of their branches, and ask to take some dogs for a trial walk. You'll be amazed at the number of amazing dogs that are perfect, loving, (already house trained and teethed) and exactly what you're looking for. You've got nothing to lose in trying it.
