Hi.... sorry, I just noticed this thread. I'm not usually visiting the Yorkies for Sale section. I just wanted to tell you to steer clear from a lady named Betty that is in the Houston area. You can find way more than you ever wanted to know at this thread......

I did get my Tatum in the Houston area but for reasons I won't get into here, I don't really recommend that breeder anymore. I got really, really lucky with Tatum but I'd hate to send you to her to have a bad experience, which could likely happen. Other than those two people, I have no other leads (or warnings) about any other breeders in that area. Hopefully you'll find what you're looking for soon. You may just need to wait until you move here and start talking to people.
