Changing behavior takes time. You need to have realistic expectations about changing your dog’s behavior as well as how long it will take to change behaviors that you don’t like. Often behaviors which are “normal” doggie behaviors will take the most time such as barking, digging and jumping. You also need to consider how long your dog has rehearsed the behavior. For example, if you didn’t mind that your dog jumped up on people to say hi for the last seven years and now you decide that you don’t want him to do that anymore, that behavior will take a much longer time to undo than if you had addressed it when he was a pup. Remember it’s never too late to change the behavior some will just take longer than others.
Second, it’s easiest to ignore unwanted behavior and reward an incompatible behavior. When Rover bites at your hands, he wants attention. He wasn’t born programmed to know that you want him to sit and ask nicely for attention, so you have to teach him. Instead of scolding him, ask him to sit. When he complies, reward him with a food treat, lavish praise and petting on him, or offer a game of fetch or tug.
Dogs competing in dog sports, such as flyball, agility or Schutzhund, must be trusted in an open field, off leash and surrounded by other people, dogs, hot dogs, and flying discs. This requires more focused attention on the owner and a better recall than that found in most household companion dogs, and more advanced training than that required for formal obedience.
Unless you plan to keep your dog outdoors--and few of us do because it's not recommended--you'll need to teach your dog where to eliminate. Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:
