Agree with Rocky ref doubling up to start with - sounds like you've got a good one there mate. Mine was hard going for training etc but started spending time with her on her own and she did come good at about 20months - I know some say they're a bit slower to mature? - like your's she walks by my side without lead, even when the others are mooching up ahead - very loyal bitch and remarkably gentle with people, glad I persevered with her.
