Getting a new puppy is a fun and interesting time. You probably went to a breeder or pet store or maybe just saw an ad on the Internet or the newspaper, for puppies, and decided just to check it out. Before you knew it those little eyes and fluffy puppy fur had your heart melting and you were headed home with him or her in your arms. If you are like most new pet owners you had visions of playing fetch with your dog, of watching him frolic at the lake, and of cuddling up on cold nights. However, you probably failed to realize that the behaviors you dream of in a dog do not come naturally. In fact, the more natural behaviors for most puppies include lovely little things like chewing up your favorite shoes, barking every second of the day, and peeing wherever they are when the mood strikes them. These behaviors might seem cute at first, or even manageable but, if left unchecked they can lead to a very bad adult dog.
