Six-week-old puppies are just beginning to learn behaviors like relieving themselves in a specific area. They are also old enough to need some regular socialization training. All of their new training will take time to become ingrained, and patience is needed with these early learners. They need plenty of positive reinforcement to learn the rules and plenty of positive human contact to make them feel safe and secure.
Set up an area just for the puppy. It should be kept in a corner or little-used room to give the puppy a calm place to rest. Puppies like small, quiet areas like crates or deep basket beds where they can go to when things are too loud and hectic around them. Puppies still need a lot of sleep, and a place of their own will allow them to retreat to a sleeping place when they get tired.
Feed him puppy food if you are feeding your puppy a dry commercial food. Puppy food is made in smaller pieces that are easier to chew. Your puppy doesn't yet have all of his teeth, so he will not be able to chew the larger, thicker pieces that are made for adults. Feed a 6-week-old puppy several times a day to keep his blood sugar steady and to give him the quick energy he needs for his energetic bouts of play.
Start potty training by letting the puppy go on newspapers. If he already has a spot where he likes to go, place papers over it to get him used to the papers. Then, move the papers a little each day until they are in a better spot for him to go. During this time, you can start taking him out for walks and rewarding him with a tiny, chewy treat each time he does his business outside. Look for treats made especially for puppies, as adult treats are generally too large for a 6-week old puppy to eat.
Introduce your puppy to plenty of people and pets so he won't be afraid or feel aggressive when he sees someone new. This socialization is an important part of a puppy's training and will help to prevent problems later, like too much barking and inappropriate jumping.
