"Splash will make a good actor dog, I think. First I found a bit of old cloth that he was used to playing with and shaking as he might shake a rat. Then I sewed this piece of cloth to my coat, so it would not pull off too easily. Then I took Splash out to the barn to train him. As soon as he saw his own private piece of cloth sewed on my coat he chased after me and wanted to get it. I ran away and we played at that game until Splash did just what I wanted him to.
