Never leave a puppy in his crate all day; he needs several bathroom breaks, as well as play and feeding times. Even though he won’t want to soil his sleeping area, if he is in there for extremely long stretches, he just might. (He can’t help it!) And if he does, it is because his owner has neglected his responsibility, not because the dog has misbehaved.
Puppies are born with a fully functional sense of smell. They are unable to open their eyes. During their first two weeks, a puppy's senses all develop rapidly. During this stage the nose is the primary sense organ used by puppies to find their mother's teats, and to locate their littermates, if they become separated by a short distance. Puppies open their eyes about nine to eleven days following birth. At first, their retinas are poorly developed and their vision is poor. Puppies are not able to see as well as adult dogs. In addition, puppies' ears remain sealed until about thirteen to seventeen days after birth, after which they respond more actively to sounds. Between two and four weeks old, puppies usually begin to growl, bite, wag their tails, and bark.
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.
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.
