Just as a child needs a caring parent; an athletic team needs a coach; your puppy needs a leader and a clear social hierarchy. If you do not take up the role of leader, your dog will; and you will end up with an unruly, disobedient dog. Many people try to win their new puppy's love by letting the puppy always have its way. Buckets of affection is a wonderful thing for most puppies, but it must be tempered with respect.
Imagine your puppy running out the front door. You call him, waving a treat. But he'd rather chase a squirrel into the road than come back to munch on a treat. In addition to the obvious danger of Puppy getting hit by a car, he learns that he doesn't have to listen to you. He learns that he's in charge of what he decides to do and what he decides not to do.
Set up his private den. He needs "a room of his own." From the earliest possible moment give your pup or dog his own, private sleeping place that's not used by anyone else in the family, or another pet. He'll benefit from short periods left alone in the comfort and safety of his den. Reward him if he remains relaxed and quiet. His den, which is often a crate, will also be a valuable tool for housetraining.
If your pup barks: Some dogs have the habit of barking at other dogs while on a walk. Oftentimes, this behavior comes as a result of lack of exercise. Make sure your dog gets the proper amount of mental and physical stimulation for his age and breed. If this is still a problem, use the same process as you would if your dog is lunging, as described above — create distance and offer treats before he starts to bark, so every time he sees a dog he gets used to turning his attention to you.
The foundation of training should be based on positive reinforcement. Positive reinforcement is the process of giving a dog (or person!) a reward to encourage the behavior you want, like getting a pay check for going to work. The idea is not to bribe the behavior but to train it using something your dog values. Avoid using punishment such as leash corrections or yelling. Punishment can cause a dog to become confused and unsure about what is being asked of him. It is important to remember that we can’t expect dogs to know what they don’t know – just like you wouldn’t expect a 2-year-old child to know how to tie his shoes. Patience will go a long way in helping your new puppy learn how to behave.
Any area that the pup has access to must be kept clear and clean. Put out of puppy's reach anything you don't want him to chew or destroy. Do not allow your puppy to have unsupervised access to 'unchewables.' Do not chase the puppy in an attempt to take something away. Instead provide puppy with her own toys and teach her how to play with them exclusively.
