Sorry for the late reply but that would have pissed me off too. Any dog is trainable,some breeds are more suborn then others but if your bonded with your animal and leader of "your pack" they will always want to please you. Thunder is four months old and already knows, Sit,Stay and leave it alone(Leave it was a big one being my dads sister visits often with her 18 yr old mini pin). The hardest thing for them to learn in my opinion is the housebreaking. That one I am still struggling with(Might I add we have only had thunder for a week and he learned all of this). I bet you those are the same people who say "Pit bulls snap and attack out of no where", the ignorance of some people astonishes me, and any good trainer would be up to the challenge and be assured in themselves that they could get it done.
