I went looking through the pages on that site. OMG!!! That is just a little of what is going on out there!! It is sooo sad. You don't know who to trust.
I have always had small Yorkies but they, luckily have been healthy.
I know that the breeder I got my little one from does raise small ones but I have been at her house and have seen that they (many) are very active healthy small ones. I think hers run around as a norm around 3-5 lbs.
