Puppies need to be trained how to do many things in order to be good dogs. It is up to you to teach your puppy how to play nice, go potty in a designated place in the yard, and walk beside you on a leash. It may take several months of focused attention to teaching a puppy how to do all of these things. Use a firm but gentle training style to guide your puppy through the lessons she needs to learn, and before you know it she will grow into a mature, well-behaved dog with a special place in your family.
