Buying a new puppy dog can be a difficult choice. Do you want to get a new-born 
                          puppy dog or one that has a little age since birth? If you are in the market for 
                          a newborn dog then you should wait until the puppy has reached the age of about 
                          8 weeks. For a older mature dog, then you should probably wait until the puppy is 
                          about 6 months old. It probably makes more sense to wait and get a mature puppy 
                          dog. This would make it easier on both the dog and the owner. More importantly, 
                          the mature puppy will most likely be potty trained and hopefully outgrown the 
                          excessive biting and chewing stage.

                          You should consider several different factors if you desire a newborn puppy 
                          dog. The newborn dog of less than 8 weeks will be in the biting and nipping stage. 
                          This is part of the hierarchal process that animals go through. Sometimes the 
                          newborn dog will bite their mother and the mother dog will growl or use body 
                          language to let the puppy know this behavior is not acceptable. Puppy dogs learn 
                          respect from their mother by about 6 weeks of age. It is very difficult to teach 
                          a puppy dog this type of respect because the dog owner is not a dog.
                          
                          Puppy dogs have a difficult time with bowel and bladder control under the age 
                          of 6 weeks old. They have not learned to “hold it in” yet as they will learn in 
                          later weeks of growth. As a result, the dog owner will have to spend consider time 
                          cleaning up the waste mess and house-training your dog will be hard.

                          A puppy dog that is older and more mature will tend to be more understanding 
                          of daily household activities and also calmer. However, you must keep in mind that 
                          this will be true only if the puppy dog has been socialized and properly trained 
                          in the home of their birth. Unpredictability, nervousness and certain amount of 
                          aggression typically will exist in puppy dogs that have been neglected. A warning 
                          to the wise is to observe the puppy dog of your choice carefully before you make 
                          the ultimate purchase decision.
