That's a good idea. But most of the time when someone loses their animal (especially in a freak accident) it is really up to them when they decide to get another animal. I am sure if anyone asked for PTer's to help them find a pet to rescue they would get tons of responses.
And if I'm not mistaken, I do see a lot of threads showing dogs that need homes. With so many dogs out there that need homes.....it would just be too much.
But your heart is definitely in the right place. Maybe this could be a thread that anyone who'd like help finding a dog can post here and fellow PTer's can help. ??
