I think it's great that you would want to keep in touch with your babies. The lady I got Scooter from, while a nice lady (and I got a really sweet pup), has never called once to check on him. I called her a few times after I got him just to thank her and to let her know how he was doing, but she really didn't seem that interested. I made sure that she had my phone number and address, even told her exactly where I lived and told her she was welcome to drop by anytime to check on him, but I've never heard from her.
I'm not a breeder, just a yorkie lover, but...if I were a breeder, I'd be one who wanted to know how my babies were doing. After all, they were yours first and they
are like our children!!! I think you were absolutely right and I don't blame you for being angry. Had it been me, it would have given me great pleasure to tell her she couldn't have one of my children! JMO
