Hi Peachie22,
It is so hard to lose a little one. My heart goes out to you.
I don't know your breeder, but Georgia is a large area. Do you recall the name of the city or region in Georgia?
A couple of other thoughts....
1. Call or e-mail the Georgia breeders listed with YTCA. Ask if they know about your breeder.
2. Check the AKC Marketplace for breeders in Georgia. Contact the breeders who are in the market. Ask if they know about the breeder you are seeking.
3. Check PuppyFind.com for Yorkshire Terriers for sale in Georgia. Contact the breeders who have pups for sale to learn if they know of your breeder.
Again, sorry for your loss and good luck.--KatysMom
