yes i have 2. They follow commands and train well. It does take time, persistence and routine b/c they can be very stubborn. after the 1st year they behave very well to how they are trained. Also, take responsibility for your actions as an owner. If you take it out for bathroom time every 3-4 hrs they will wait for that time. If you forget and wait 6hrs then it's your fault, not theirs.
