Thanks Jodi, some great tips.
And, diannenet that is a good idea to pass this info on to others.
Sadly, we have "found" the same yorkie boy in our neighborhood 4 times now. Each time we've taken him back after that 1st time, I've wondered if we are doing right by the dog. We went door to door looking for his owners and they were not even aware he had got out. I wonder how many chances an owner should have?
