Maybe in a fantasy world where you already know the number, color, gender, and drive levels of the pups you're going to produce within a few weeks after being bred.Any REPUTABLE breeder will already have homes lined up for the puppies they bred
A LOT of excellent breeders don't line up homes for puppies until they know what they have.
While I agree that advertising Pits on a hand-lettered sign doesn't exactly recommend this person as a paragon of ethical breeders, the notion that a breeder must have homes lined up for every pup bred is absurd. What if you line up 4 homes and end up with 14 puppies? What if you line up 10 homes that want males and end up with 3 females? Or 7 working homes and 3 pet homes and end up with a litter of mostly pet-type dogs?
