Avoid the extremely shy, retiring pup. Unless you're willing to give him extra love and attention, he is likely to be a misfit. His eyes should be clear and bright. His nose and ears should be clean, with no sign of discharge. The skin should be clean, with no hairless or red spots.
Constant scratching is a sign of skin trouble or parasites.
The coat should be glossy and not shedding excessively. The breeder or kennel owner should furnish information on the puppy's vaccinations and worming. This will be an aid to your own veterinarian when the puppy is taken for a checkup and, if necessary, follow-up vaccinations and wormings. The breeder also should provide written instructions for feeding. Many breeders give new puppy owners a few days' supply of the product which the puppies have been fed.
