Since Doisy is much more pleasant to be around since he is no longer hormonal, I've been working with him more, especially recall training. Today I upped the challenge because he was really eager to fly. I started calling him when I wasn't in the room but he could still see me. It was a major step for him to fly through a doorway. Then I made it even harder and moved out of sight. He was helped out by the fact that Rodrigo quickly figured it out and Doisy can't stand to be one upped. So now I'll have to practice having Doisy and Rodrigo fly to me based on sound. 
Great progress. 
brilliant!
