I agree with you on robot dogs. They're often the product of training methods endorsed by Cesar Milan and the like. The term most trainers use for those dogs is "shut down." They're so afraid of making a mistake that they won't do ANYTHING to risk a correction. They've totally shut down any natural curiosity/personality/playfulness.
It's very sad.
Awhile back someone posted a video of a man walking a pack of GSDs w/o a leash, as if that was a good thing. Every single one of those dogs cringed or flinched a tiny bit every time they glanced at the man (some obviously did everything they could to avoid looking at him). Some of it was subtle, you had to watch very closely and know what you were looking for to notice it. I wish I had brain bleach to get that video out of my mind.
