Were you able to contact the shelters and rescues listed under Michigan that are posted on the petfinders list? (up at the top, right of the page?)
I sure hate to see two healthy dogs get put down. I feel so bad when even Gaylord, who couldn't walk well was even adopted and at GSD rescue, the amputee was also just adopted. It hurts when healthy dogs have to die.

Again, thanks, Leslie for doing your best to try and help these dogs.
