During initial sessions with your dog trainer , it is important to let your dog know when he has done the right thing or the wrong thing when first teaching a new behavior. This is the basis of obedience training. Offering the dog a favorite treat or toy when he does the right thing will teach him to repeat the desired behavior when asked. It is equally as important to let him know when he has done the wrong thing. This can be accomplished by saying the word "No" and then guiding him into the proper behavior each time. By consistently guiding the dog into the desired behavior after each “No” instead of physically correcting the dog, the dog will soon start to offer the correct behavior when he hears the word "No." This type of dog obedience training technique is common among today’s positive-motivational trainers.
