It typically takes 4-6 months for a puppy to be fully house trained, but some puppies may take up to a year. Size can be a predictor. For instance, smaller breeds have smaller bladders and higher metabolisms and require more frequent trips outside. Your puppy's previous living conditions are another predictor. You may find that you need to help your puppy break old habits in order to establish more desirable ones.
Your young puppy is totally reliant and dependent on you to help him habituate and fit into our human, domesticated world. Your guidance and leadership will determine what path his life takes and what type of dog he will become. During puppyhood you play the lead role and are responsible for shaping the character, temperament and behavior habits that your dog will carry throughout his life. Your puppy's future is in your capable hands...
If he's an older dog, he's probably used to his name; however, changing it isn't out of the question. If he's from a shelter, they may neglect to tell you that he has a temporary name assigned to him by staff. If he's from a breeder, he'll come to you with a long name, which you may want to shorten, or change. And if he's coming out of an abusive situation, a new name may represent a fresh start. But we're lucky: dogs are extremely adaptable. And soon enough, if you use it consistently, he will respond to his new name.
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.
Puppies develop very quickly during their first three months, particularly after their eyes and ears open and they are no longer completely dependent on their mother. Their coordination and strength improve, they spar with their littermates, and begin to explore the world outside the nest. They play wrestling, chase, dominance, and tug-of-war games.
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.
