''Pick of the litter'' puppy
First, let's clarify what a pick of the litter is. ''Pick of the litter'' is a puppy, that the breeder considers to be the best of the entire litter, based on the puppy's conformation, movement, type, temperament... usually this puppy will stay at home and live with the breeder, however it may happen that a breeder can not keep the puppy (to provide a quality life we can not have 20 dogs at home ;-)) or maybe they've found that 2 puppies are of similar quality and have decided that both of them should be a part of their breeding program. If this is the case, the breeder will often try and get their pick of the litter into a co-owner's home, meaning the puppy will officially have 2 owners (the breeder and their new owners), live with the co-owners and return to the breeder on several occassions. When and how often a co-owned puppy visites the breeder varies from situation to situation.
