When Jock takes the hurdle cleanly every time, alter your own routine by not stepping over the hurdle as you and Jock reach it. You and he are now on opposite sides of the obstacle and in all probability he will quickly jump back to your side when you call “Hop!” If he is a good big dog you will probably find a fairly long cord is better than your leash for the jumping lessons as that will obviate any possible jerking when he takes a longer leap than you expected.
The fact that Jock probably enjoys the whole performance as much as you do may make him so eager to jump he will get to the hurdle first, jump it ahead of you and, unless you let go the leash, get a sharp twist of the neck. This is dangerous. To make the jump with a dangling leash may mean all kinds of trouble, and if Jock is the sensi
tive sort may set him against the whole jumping proposition.
The long cord will be your ace in the hole, as you can see. But you must avoid the necessity of using either leash or cord later on, so you might as well plan for it now. Vary your routine by stopping short or making a left or right turn as you walk toward the hurdle, ordering Jock to heel as you do so. This will make him uncertain whether or not he is to jump at all and he will hold his place at your side until you are near enough the hurdle to give the order “Hop!” Also give the order “Down!” when Jock has cleared his hurdle to prevent him from jumping back again without waiting for your command.
