I watched a documentary a while ago on a girl called Oxana Malaya, who was brought up by dogs since she was 3 years old. Her parents were alcoholics, there was no space in the house for everybody to sleep in, and so one night, the girl crawled in a kennel with dogs and that's how she spent most of her childhood. When she was 9 she was taken into a mental hospital after a neighbor reported on her to authorities. I found a not-so-good clip on Youtube about her:

What's interesting is how she adopted to dog culture - she has had the same "problems" as we see in our dogs: she has little emotional control, zero boredom tolerance, she is very pushy and physical. She doesn't believe that words are necessary to communicate at all... which just shows you how dogs see our conversations with them as useless blathering about. One other thing I wondered about is whether or not she was raised as an "alpha"... According to the documentary I watched, the mother dog "raised" her - Oxana even drunk her milk with other pups. Apparently, when Oxana was taken in, the dog ran after the van for miles and miles, until she passed out.
Also, there is a similar and opposite story of a 4 y.o. Ivan Mishukov who's been treated as an alpha by a pack of stray dogs downtown Moscow. He won their trust by getting food for them (by begging, etc.), and they in return protected him and kept him worm in cold weather... (It took a few goes for cups to pull out a boy and take him away - the dogs aggressively protected him.)
That got me to thinking, if Oxana didn't take an alpha position, that must have worked out OK... there must have been a mutual understanding and a good relationship with other dogs in a pack! Granted, the girl lived in a dogs' world, not as we are used to thinking about it: the dog lives in "our" world, therefore, teach it our way... be its leader. Makes me think when dogs need a human as a leader... And that's what's interesting. Search and read a bit about her, it poses some questions I think.
