I just want to say I feel badly for both parties involved. I don't know who is at fault as there are only two people who know the real story.
I took a look at your site and I must say that the "rare chocolate" that is from your Pachex and Nitro really concerns me.
She doesn't look like a true chocolate, a true chocolate has a liver color nose and pigment.
Her hair is very sparse and thin which leads me to believe she is a blue born. Her nails are very long and really need cut. Altogether she looks very unhealthy and if it were me I wouldn't be selling her at all on certainly not for $2500.
I don't know if you are uninformed about blue borns and mistakenly took her as a chocolate instead but blue borns develop severe health problems and the parents of course should be spayed and neutered right away.
Here is a link to blue borns and what a blue born pup and a chocolate pup looks like.
