I don't know how much actually being outdoors matters. I suspect that getting exposed to a forest environment; cold, bacteria/molds in the air, sunshine, and so on might matter too. Even possibly eating gamely animals. I grew up on a farm, so I know that dogs that are kept outdoors, act differently than dogs that are kept indoors. They are more aggressive, appear fitter, and smarter. I suspect their brains might develop differently from living outdoors.
