I don't think anyone here has or had a problem selling their puppies.
I have also been very lucky to find great homes for all my babies. I have a litter now and all but one is sold. I start early with the advertising and as people call and come over I get to meet with them and find out if I think one of my puppies is right for them. I just turned a older woman down because she told me she had a yorkie, but had to give him away because he had troubles with his trachea and he was always throwing up all the time.

I had to tell her I didn't think she was a good fit for a puppy.
And to add, a lot of my buyers/owners come back to buy another one or two and tell their friends, so I always have people waiting just around the corner for my girls to have a litter.
