By the way, Pekemom, I can see that you're putting a lot of thought into your pups and I really do commend you for keeping such an open mind. But the issue of pet overpopulation is just as bad, if not worse, down South/in the boonies. I was reading an article about pilots who fly pets from overpopulated areas into areas with less of the problem. Here's a quote:
The mission-of-mercy relocations are flown by general aviation pilots who have signed on with the recently formed Pilots N Paws, a Web-based message board where pilots can access information about animals in need.

Once the electronic connection is made, dogs plucked by rescuers from death row — mostly in the South where sterilization rates are low and pet overpopulation is rampant — are loaded onto small planes and flown one, two or six at a time to rescue groups and shelters that have available space.
Some food for thought
