I've been clicker training my two to "give" recently. That is, deliver an object that's in their mouth to my hand. I've had great success with this at home, but been having difficulty transferring it outside. The big problem I have is with the snow - when they are carrying something int eh snow, it's a great game to drop it and then mouse-pounce on it until it's buried, then try and find it again. This morning, I managed to find a little place in the woods where there was bare ground, covered in pine cones. It was about 5 feet diameter, so pretty cosy, but I sat down and started right from the beginning of the give with the cones that were to hand. They did really well, even with the distraction of the other dog mouse-pouncing in the snow and their little border collie friend, who had decided to join us. This afternoon, I've done another session inside, varying the object between a regular dummy, a pheasant dummy, a rubber ball, a Kong ball and a pine cone. These have varying degrees of attraction to the dogs, so we started on the easiest (the dummy) and finished on the hardest (kong ball for Shadow, rubber ball for Willow). Willow, especially, came on really well. She got the idea that she could play with the ball as much as she liked until I asked for it (that is, I ignored any attempts for her to give it to me when I hadn't cued her), and once she understood that, she really relaxed into the exercise and became excited when I asked her to give it, knowing she'd get a tasty treat, plus the ball back. By the end, I had them both wandering round the living room, playing with their balls and playing together, but trotting up to me to give it to me when asked. Very pleased, and now we just have to transfer more of that behaviour to the big wide world.....!
