Some dogs play silently, while others love to vocalise. In this case, barking occurs while dogs play with one another, or while you are playing with your dog. Barking for play may also be directed at an object (ball). An excited or agitated dog needs good training and good leadership. Simply adjust the collar onto your dog before a playing period. As soon as he receives the citronella spray, us a command and wait until he is silent before offering a reward and resuming play. Consult the section on the "Stop" command for further information.
