Someone Dumped a Puppy on Our Vacant (fenced) Lot
I'd have fed her for couple days to get her strength back up and maybe taken her to the country and re-dumped her if I didn't have any other options, rather than have her locked up at a pound with minimal chance at life. At least being re-dumped, she might find a home. And you know how it is... You can never bring yourself to re-dump them and next thing you know, you don't know how you go without her.
That said, I'm on a rather large gun website and I suspect she would've been homed quickly there. Those guys will network a dog transfer across the whole country if they have to, and with her having some German Shepard, that would not have taken long.
Bless Miguel. That's a bravo maneuver if I ever seen one.
