In teaching this trick two ladders should be provided about six feet in length and joined together at the top ends so as to form an angle when the other ends are placed on the ground. The bars of these ladders should be flat and sufficiently near together to enable the dog easily to step from one round to another. Standing at the side of this ladder with a switch in your right hand you whistle to the dog, or call him by name, and tap the first round of the ladder with your switch to indicate he is to step upon it. When he places his fore paws on this round, tap the next in the same manner, saying, “Go on,” to him.
