So you want something that will listen to your every command? But all lifeforms: humans, animals, plants, micro-organisms, etc., have a will of their own. If you're looking for absolute obedience without any questioning/resistance, well... not even an animal will be able to give you that.
Actually, I suggest that you keep the dog 'cos contact with animals often allows children to grow up with better empathy towards people and other animals. But ultimately, it's your choice. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Edit: Perhaps he's resisting you 'cos he knows doing that will piss you off?
