I think it's commendable if you go through a reputable breeder! IMO, there are only two places where you should acquire your dog: 1) a rescue/adoption situation or 2) a reputable breeder. If your case falls under either of those two, I think you're safe.

Tealbrook looks quite nice! The only thing that made me go "Hmm..." was the Better Business Bureau logo at the bottom. They don't seem to be actively advertising their puppies, however, so I'm not too concerned, but you might want to ask them why they're affiliated with the BBB. Usually, when you put the words "BBB" and "puppies" together, you think of some puppy mill like WOC, but the rest of the website looks quite reputable. It never hurts to ask

And about the adoption/breeder situation, I agree with the rest. It depends on which puppy you "click" with the most. I know you're excited, but a lot of breeders and rescues don't check their e-mails or voicemail daily. It's quite a struggle to maintain their daily life while taking care of those dogs (I can't IMAGINE taking care of 69 dogs!!!). Giselle's foster mom had her hands full with 15 dogs. I can't imagine nearly 5 times that! Would they allow you to drop by the shelter in person? If not, just wait it out
