The next option is called luring. Get down in front of your puppy, holding a treat as a lure. Put the treat right in front of the pup’s nose, then slowly lift the food above his head. He will probably sit as he lifts his head to nibble at the treat. Allow him to eat the treat when his bottom touches the ground. Repeat one or two times with the food lure, then remove the food and use just your empty hand, but continue to reward the puppy after he sits. Once he understands the hand signal to sit, you can begin saying “sit” right before you give the hand signal.
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...
Puppies are highly social animals and spend most of their waking hours interacting with either their mother or littermates. When puppies are socialized with humans, particularly between the ages of eight and twelve weeks, they develop social skills around people. Those that do not receive adequate socialization during this period may display fearful behavior around humans or other dogs as adults. The optimum period for socialisation is between eight and twelve weeks; professional animal trainers and the American Kennel Club advise puppies should be introduced to "100 People by 12 Weeks" and have encountered a wide and varied selection of people and environments.
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.
