If she is going to be alone during the day or night, she needs to start getting used to it now. If she wakes up from a nap and whines, resist the urge to run in and comfort her. Since puppies are so impressionable, it is important to begin explaining the rules right away. Don't give her special license to get away with anything just because she is a puppy. If you allow her to have her way about certain things now, she will only be confused later when you decide to change the rules.
Puppies learn very quickly with proper instruction.
Never hit your puppy or give harsh reprimands. They don't mean to misbehave - they are just doing whatever comes naturally. Instead, show your puppy what kind of behavior you want. Teach her to play with her toys. Make them fun and exciting.
