This goes back to Lesson #2 learned early on in my dog walking career: "Always take at least one more poop bag than you need when walking dogs." If by chance I use the last poop bag I have on me, by now I should remember not to tie the bag up so tightly. Inevitably the dog will poop again and I am stuck trying to untie the bag.
