I was trimming in front of a customer's house today when what should walk around the corner but their dog. This mutt was big, loud and had no intention of taking me home to meet momma. Thankfully, the dog was afraid of the weedeater. I considered packing up and leaving but I had just started and also had the house next door to do so I just kept working albiet much slower than normal as I kept one eye on the dog. The customer was not at home but I had their cell phone number on my caller-ID so I called them to tell them what was going on. They were surprised that I had kept on working. I think that I am too as this could have been trouble. What do the rest of you do when confronted my a not-so-friendly dog?
