Gals I suspect she might be gone. She found out her gal wasn't pregnant.
Now she has all the time to research what she should on the breeding, whelping and rearing of puppies - well at least six months maybe more.
I suspect she knows a little something about breeding. Maybe not this breed.
To the OP
So glad we could be of help. Please visit
www.ytca.org this is the National Club for the YOrkshire Terrier in your country.
You could also visit Deb Jensen's site on whelping.
I can only urge you to read a lot about the genetic problems with Yorkies. You can start your reading here in the Sick and Emergency threads.
Please do breed for health and temperament and I do hope your young gal is healthy - although I do wonder why a "breeder" let a young female go at the late time of 12months? Did that original owner know something you didn't?
