It's great that you are doing this. But, don't rely on it alone. Microchips float, especially on active dogs. My girl Gabby, was micro-chipped 3 times and they still didn't find her for me. But, the good news is that she was taken in by a rescue and they placed her in a wonderful home with children, which she always loved. I chose not to pursue getting her back after 2 years. It was enough to know that she is loved and happy. Put all the identification tags you can on your dog even if you do have them micro-chipped! AND everytime you go in to see the vet or are somewhere that they can scan your dog.... HAVE IT DONE to be sure it has not floated
