My daughter showed me this... some of you might find it interesting. It shows a distinct difference between wolf pups and dog pups when both are hand-raised and treated equally by humans.

There was an interesting show on the tube (hell, it's not a tube anymore is it!) this last week, about how dogs had been bred for certain characteristics. It has some of the same experiments as this video...to me it showed how independence had been bred out of wolves (or that dependence had been selectively "bred in" to dogs)...not, that wolves where inherently more independent.
I noticed in this video that the human wasn't displaying alpha behavior...she was, in fact, very submissive. I'm sure this had a lot to do with the puppy "not caring" what the human (the only other animal in the pack) did. Also, the pup and the human are both females...so, unless there is distinct alpha status behavior from one, the other will challenge for alpha status.
