How to pick a puppy from a litter
Try to buy a puppy from a breeder instead of a pet store.
While it may be tempting to scoop up the adorable pup in a pet store window, buying a pup this way can be risky. Most pet store puppies are on their own in a small glass cage.

[4]. You don't want to be in the middle of a store where you find a puppy that you know the breeder or owner has a wary attitude toward. Choose a breeder who is comfortable with you and your home.
