This is a great little organizing tool, especially if you are a multi-dog (or kid!) household. In our organization, some of the harnesses are shared by more than one dog. Instead of fumbling through all the equipment and finding the right sized one, I put a little card in the dog's "pocket" that lists whose harness he or she shares. Each dog has a pocket that holds his collar, tags, etc. and other important info. And in an emergency, you can just fold it up and take it along quickly. Lots of possibilities for this, to help simplify your life!
