work for you and many won't let you select the puppy, they decide which of the litter best fits potential owners. If you're applying for a chance to purchase the puppy you've probably found a good breeder.
I will never be that kind of dog person but I can appreciate people who are.
Most dogs in shelters are there because of bad owners, bad temperament, or both and they can be a handful. I don't have that kind of patience.
