Faith was born with her hind legs and part of a front leg (which had to be amputated).
She learned how to adapt to the situation and walks nearly erect. Notice how her tail is used for counter-balance.
Teach a person (or dog for that matter) how to function and their form adapts to the stimulus given it.
The common perception is that if you change someone's form then their function will change. I agree with this to a degree...once someone is in a chronic state then they can more easily address their habitual natures and learn to change their functions to more satisfying and efficient experiences.
Learn to live life more fully as a human being, or as a more full human doggie!
