Service Dog Patches and Vests/Capes

Just an explanation of some patches that I have found to be either really helpful or useless. :) I know I obviously didn't cover every patch out there (there are so many), but this is what worked and what didn't work for me, and why. AND PLEASE EXCUSE THE GIGANTIC MESS IN THIS ROOM!!! We're cleaning out the house right now, is this is where we're throwing all of the boxes and paper garbage and other crap.... Sorry about the mess. :)
