Yes, yes, yes.  Get a chip.  One day we were on our way to the store when we saw a yorkie running down the sidewalk with his head up high and looking confused.  It was a busy arterial.  We stopped and had quite a bit of difficulty catching him.  He was frightened and dirty, needing combing.  We could not find any identification so we took him to the local animal shelter.  We told them we would come back to get him if no one called to claim him.  It so happens that the owners called just a couple of hours before his time was up.  If someone does not claim a lost dog it can be euthanized or adopted out.  We were relieved to hear the news.  If this lost dog had been microchipped his owners would have been called immediately by the shelter.
 
If our little Wiggle Wolf ever got lost we would probably sell our house to get him back.  It is like loosing a child.
