Hi and welcome as I don't believe I've met you on YT yet.
First of all, I am so sorry you are being harassed. Regardless of personal beliefs, no person should harass another.
The picture of Hattie at 7 mo. is the cutest thing ever!! I do think that your prices are very high, but that is my personal opinion. As a breeder, you have the right to sell your puppies at whatever price you choose.
I'm not a fan of the term "teacup" only because it is so widespread and misused. People seem to think it's a special type of Yorkie so I always correct them. But, for lack of a better, word... you could just call them "Tinies."
Anyway, I hope you get your issue with the harasser solved. And keep reading here at YT... I learn something new every day!
