Claus is learning that he has back feet. We went to a friends house and worked on her agility equipment. We are also dealing with having to switch to a verbal marker for a while as the duty holster clicks when you return the pistol to it and that has interfered with his obedience on the shooting range. Hopefully though the agility work will help him with his ladder climbing skills. He is fine if you set him on the ladder but otherwise he forgets he has back feet.
