On another training angle...he has learned to touch the target stick in all directions as well as look at it on cue. He will also take and tug a canvas tummy on cue. His sit and down stays have improved to the point where I no longer need to use the Comfort Trainer or leash. His heeling often still requires the Comfort Trainer if he is in a distraction zone. We are also working on the "sleep" cue, where he'll lie on his side with his head down. He can hold that for about 10 seconds with me close by his face.
While he and Lola have become good friends, he still challenges Princess and Jasmin snaps at him every time he gets near her. She also goes after him when he plays with Lola. She really dislikes Pumpkin. Princess tolerates him, but only because I make her.
