You might misunderstand me. I also have a living creature as a pet, not a robot but I couldn't for even a second imagine my dogs biting me because I pushed their bottoms down to sit. (maybe if they were in a LOT of pain) I do watch for signs of stress or discomfort in my dogs and I wouldn't ask them to do something that would hurt them just because I can. I also would NOT expect my dog to bite me because it simply doesn't feel like sitting and I push down on its butt. If I beat them or hit them I guess I would deserve a bite but not just for putting a little pressure on their butts. Also we are talking about a pretty young dog. Maybe I have had the same breed for far too long but at that age, I wouldn't expect too many grumpy days. Which is why I immediately wondered about health.I don't have a robot, I have a living creature that has her own complex set of rules and feelings. If my boss says jump usually I say how high, but not every day is the best day for that. Why should I expect my dog to be more perfect than me?
Most people think their dog is completely friendly, yet the dog is constantly giving off warning signs that it's not. It's not black and white, the dog isn't either perfectly friendly or an attack dog.
