In choosing a puppy, assuming that it comes from healthy, well-bred parents, look for one that is friendly and outgoing.  The biggest pup in the litter is apt to be somewhat coarse as a grown dog, while the appealing "runt of the litter" may turn out to be a timid shadow - or have a Napoleonic complex!  If you want a show dog and have no experience in choosing a prospect, study the breed standard and listen carefully to the breeder on the finer points of show conformation.  A breeder's prices will be in accord with his puppies' expected worth, and he will be honest with you about each pup's potential because it is to his own advantage.  He wants his top-quality show puppies placed in the public eye to reflect glory on him - and to attract future buyers.  Why should he sell a potential show champion to someone who just wants a pet?

Now that you have paid your money and made your choice, you are ready to depart with puppy, papers, and instructions.  Make sure that you know the youngster's feeding routine, and take along some of his food.  For the trip home, place him in a comfortable, sturdy carrier.  Do not drive home with a puppy on your lap!  If you'll be traveling for a few hours, at the very least bring along a bottle of water from the breeder and a small water dish.
