Mags, first of all, welcome to Pet Talk!!

And secondly, I'm very sorry to hear about your puppy There'll be over 800 pets up for adoption, so there is a chance one might be a GSD/mix. I'm not sure exactly what will be there but you should definitely come and see if any of the dogs there catch your eye.

you can also check out www.petfinder.com to find dogs available for adoption in your area...

Here are a couple links to GSD puppies available for adoption around you.
