In the south, primarily GA and the Carolina's, shelters give dogs a relatively short time, like 2 weeks, to be adopted from before they gas them or in one instance, shoot them. Most of the flights I make are for organizations who claim them and send them to NY where they are put into forever homes, or fostered until a home can be found.
As posted in the other thread, a lot of kids come to the airport to pick up their dogs, and end up sitting in the right seat of an airplane. How can that be a bad thing?
I gotta burn avgas to stay current anyway...
