I'll be heading up to Austin on Saturday, are the shelters open that have the Rottie pups and do you have the contact info for them?

As for the shelters, yeah I didn't think about animals born in the shelters. I can't see why anyone would drop off purebred pups though when they can get good money for them. Years ago my neighbor's lab decided to bust through a fence and take my lab out on a date when she was willing, she had 11 pups. 7 of those pups went for premium $$ and the last 4 I dropped to $50 when they hit 10 weeks because I wanted them to go to their final owner's homes while they still had a chance to bond. I had people beating down my door to get those last 4 pups and I got calls for them for weeks after they were gone.

Apparently the work it would take to search for a rescued puppy isn't on your agenda.
I've already stated that we're rescuing a house dog soon, but sub-par rescue dogs (allow me to rephrase, rescue dogs with sub-par childhood/upbringing at a young age) are not going to fly for a working dog that will have so much expected of it and I am still seriously doubtful that I could find a 7 week old lab puppy at a shelter, so no I have put no time into looking for a Lab pup at a shelter.
