Dear Mindless Dog Hiker,
As I closed the distance catching up to you on the single track trail, I noticed your bounding dog frantically dashing around like a fly trapped inside of a window. No leash? I guess that explains the neon yellow doggie vest so you can spot him up to a mile away. Suddenly, his goofy brain focused on me and he transformed from a buzzing fly and into a charging bull.
