Ha, I had a lovely Golden who was my model and assistant in my classes for many years. My BIL came to visit and was amazed at his training. He said the dog was so well trained he bet he could get the dog to do anything so I said he could try. To his surprise the dog acted completely deaf and unresponsive. Wouldn't come, sit, nothing. He would not obey anybody but family. I used to demonstrate that in kindergartens and VBS classes to show children the importance of never going with strangers. Would put him on a Sit-stay and leave the room, telling the kids they could call his name, clap their hands, whistle or whatever to get him to come to them. He would just sit there and grin. But when I came back and told him, "Okay, go visit," he would run around the room greeting everybody. Very friendly dog. Uh. Now I am missing him, lol!
This is fantastic. (Especially for a Golden, who will generally adore anyone with food or a ball—I grew up with them and know! Ha!) Do you mind explaining how you did this? Very impressive. (Plus great way to teach little ones about strangers.)
Sorry you miss him so much...I know exactly how you feel. But we don't miss them if we didn't love them, too.
