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.
Basic or beginner's obedience is typically a short course ranging from six to ten weeks, where it is demonstrated to the handler how to communicate with and train the dog in a few simple commands. With most methods the dog is trained one command at a time. Though there may or may not be a specific word attached to it, walking properly on a leash, or leash control, is often the first training required prior to learning other commands.
You can start training your dog before they're of age to compete. Begin by working on basic obedience and teach your puppy to sit, lie down, come, heel, and stay. Your puppy will also benefit from attending training classes where they will learn basic obedience and get used to working around lots of other dogs and people. Having your pet take and pass the AKC Good Citizen Test is a helpful step.
At a basic level, owners want dogs with which they can pleasantly share a house, a car, or a walk in the park. Some dogs need only a minimum amount of training to learn to eliminate outside (be housebroken), to sit, to lie down, or to come on command (obey a recall). Many other dogs prove more challenging. New dog owners might find training difficult and fail to make progress, because they expect dogs to think and act like humans, and are surprised and baffled when the dogs don't.
