Your buyers are not the boss, the seller is. Make sure you inform them of all the consequences of not spaying; cancer, roaming male dogs, being in heat as a whole. You obviously don't have a puppy contract. I agree with all of the people on this board. I think you are confusing the meaning of backyard breeder. It has nothing to do with the dogs actually being in your back yard, and everything to do with the reasoning for breeding and the poor caretaking methods. By the way, it wasn't until like the third page that we found out you were deaf, and they were yelling at you long before then, no discrimination there. I also do kind of hold you responsible for the death of the other dog, did you just sit there and watch it get sicker and sicker without doing anything?!
