Training is a person communication with their dog, on a level that their dog can understand. It is up to you to learn wha t to do, when to do it and how to do it to make your dog understand what behavior you want or do not want . Some things you do in training may make more sense to one dog than they do to a different dog, because of the individual differences among dogs. There are more pronounced differences between individual dogs within a breed than between different breeds. With all dogs and people, the training theory is the same but the application of the theory may be different.
Excuses are convenient, the truth is awkward.
Never correct a dog out of anger. It s just one dumb animal trying to train another. Never correct as dog that is coming to you. Break down exercises and teach the smallest parts. Food motivation is a reward NOT a bribe.
