I just got him one week ago... and he had NEVER been walked in his life before. He had a yard to run in, but spent most of his time in a crate while his owner was away on travel. He does fairly well while on his own--but, he's easily distracted. If I take him out with our other GSD, all he wants to do is play rather than walk.
I enrolled in basic obedience, but we've only been one time so far. This saturday will be our second class out of six. I do plan to continue out training though after this session ends. So really, we just started working together.
He didn't even know "shake" or "paw" when I got him.. but, he learned that in less than a week!!!! He knows 'sit', 'down', 'stay', and 'wait' though.. so I cannot complain. He's always house trained.. it's just walking and nipping that present the biggest challenge so far!
