Sounds good to me!
It is tough and people make mistakes...not saying you did. In fact, she couldn't be in better hands most likely. It's just a shame that the breeder let her go so young is all. They're the ones to blame for not looking out for her best interests, not you.
Keep up the good work and don't be afraid to seek professional help for her if she develops any issues from being taken from mom so young...it's not something you did/didn't do, it's just has a higher percentage of happening vs. a puppy that had the opportunity to hang around for a few more weeks.
Thanks for the update! So....where are the new pictures of your pups? Post 'em up proud momma!
