You may have already done this, but you might want to also post this on craigslist, petfinder, and call Animal Allies, who can give you more information on what to do.

Thanks to you both.

Poor guy - he looks so sad! I hope he finds his way home soon!

Great!  Now, get him a tag with his name and your phone number.  They sell them up at Petco.  He seems too nice to lose again!

Just thought I'd let you know my girls and I were meeting some friends at the 43rd Avenue East park when they showed up walking with your dog. Apparently, he followed them from the Lakewalk. Your dog was in good hands for that 1+ hour when we all (kids included!) were petting him trying to see if he had a tag. He seemed to really enjoy the park with all the kids! Glad to hear he made it home safely.

Yay! I'm glad he's home safe!
