I am SO sorry. I know the pain of seeing a young puppy die due to a congenital illness. I had one as a foster and we had her at a specialist and were prepared to spend whatever it took; but her congenital anomaly was so bad she could not be saved. Made me sick. I have never really gotten her out of my mind...she never had a chance.
I would not let this woman go. I would hire an attorney and do whatever I could to make her pay. Yelling at you that you killed a puppy who had a congenital defect? Horrid.
I looked at her site and the first words that jumped out at me :
We breed tiny,
I don't know her or her breeding program, but most breeders who use those words do NOT put the pups welfare first. It is all about the bottom line: money and using that "tiny" word to get money from people. Tiny = teacup in my way of thinking...some just avoid using the teacup word but the breeding remains the same .
