Researchers have described several reasons why the dominance model is a poor choice for dog training. First, a relationship based on dominance is established to gain priority access to scarce resources, not to impose particular behaviors on the less dominant animal, so the dominance model is irrelevant for most of the behaviors that people want from their dogs, such as coming when called or walking calmly on a leash. Second dominance-submission relationships, once established, are constantly tested and must be regularly reinforced. Thus people, particularly children and the elderly, may not be able to retain their rank and are at risk of being injured if they attempt to do so. Third, dominant individuals gain priority access to resources, but only while they are present, establishing dominance over a dog does not guarantee its behavior when the dominant individual is distant or absent.
In the 1950s Blanche Saunders was a staunch advocate of pet-dog training, travelling throughout the U.S. to promote obedience classes. In The Complete Book of Dog Obedience, she said, "Dogs learn by associating their act with a pleasing or displeasing result. They must be disciplined when they do wrong, but they must also be rewarded when they do right." Negative reinforcement procedures played a key part in Saunders' method, primarily the jerking of the choke chain. The mantra taught to students was "Command! Jerk! Praise!" She felt that food should not be an ongoing reward, but that it was acceptable to use "a tidbit now and then to overcome a problem." Saunders perhaps began the shift away from military and police training methods, stressing repeatedly the importance of reinforcement for good behaviour in training—a move toward the positive training methods used today.
Be persistent! Make sure the puppy doesn't get the opportunity to pee and poop by using a leash indoors or confining him to a crate when you're out. Depending on the puppies age, pop him outside every 20 - 30 minutes, so there's a greater chance of him toileting outside (by accident at first.) In addition, get rid of any scent markers he's left by peeing or pooping indoors, as these will draw him back to the same spot. This means cleaning the area daily, for 2- 3 weeks after he last pooped there to fully get rid of any lingering odor that the dog can detect.
Once he seemingly has this idea down, move the string of bells to the left or the right of your dog and see if he moves to go and hit them with his nose; if he does click and treat! Next try moving the bells above his head and then closer to the floor. If he is chasing them with his nose in an attempt to ring them, then he understands what you want!
A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog.
