If you’d like your dog to become better and faster learner who is motivated and engaged during training sessions, then improving handler mechanics is one of the key things to work on. You don’t have to spend more time training your dog in order to get rid of stressing high or low behaviors like sniffing, walking away from the training session, barking, frantic movements. Having clear mechanics and reinforcement delivery will almost always result in a better training experience to you and your dog.
