I am not a breeder but had an accidental litter (sorry for my ignorance...Bitsy is spayed now) but I turned down lots, lost count, when I sold Bitsy's pups. One lady drove all the way from the Raleigh area to my house to buy two of my girls and I was soooo excited that they were going to get to stay together,but when she got here, she wouldn't sign my contract so she didn't get the girls...on the phone she said she didn't plan to breed them and I told her she'd have to sign a contract and also that I get first chance to take them/buy them back if things doesn't work out.... but when she got here she changed her tune and becasue she drove all that way I think she thought I'd give in and just let her have them....I didn't.
Another lady in particular in my area, long story short, turned out to have a backyard full of s**tzu's that she kept outside and she was tricky too but I had a bad gut feeling about her to start. She sent me a very nasty email and she didn't like my contract either. I told her to take two of the indoor dogs that she keeps outside and bring them inside and treat them with the love and respect that they deserve, instead of bringing two more dogs into that kind of situation. I didn't hear from her again
I made a few enemies while finding them good homes, but I DID find them WONDERFUL homes!!! I found that the people who were willing to sign my contract had good intentions for my babies.
