Wow! I got such a mental image I felt like I was there! I have mixed emotions on this one. Years ago my childhood dog was attacked by an unleashed dog (his human was no where in sight, so it was a little different than your story). My dad was walking him and the ensuing fight was horrifying. My mom said my dad came home shaking and our dog was rushed to the vet to get patched up. My first thought was that I would have probably reacted in much the same way as this man, (scared to death! ! ) although I of course don't carry a gun! Thankfully he didn't totally overreact and use it! Do you remember several months ago there was a story in the news about a police officer who shot a family's dog on a car stop on the highway because it was running toward him!

My only suggestion is this. My Bella is a tugger and would prefer that she takes ME on walks instead of the other way around. I invested in a Halti and it has changed things 100%. Your other option would be to enroll your dogs in an obedience school and learn how to take control of them on walks. This is not an overnight cure and it will cost some money but is something you could consider. In the meantime I would certainly walk them separately and, at the least, check out the Haltis or Gentle Leaders at your local pet store. Good luck!
