I think even if you did everything correctly, as Jane as pointed out, because of the area you live in, which is full of puppy farmers, you may struggle to find homes for your pups. I too have a friend in your area that has now given up breeding, her last litter she ended up selling for £300 as she couldn't find homes for them, she was an Assured Breeder and all her dogs tested too, she also had her affix.
