So, last night I'm leaving work, heading to my car. I'm parked waaaaayyyy in the back of the lot. There are only a few cars around by there is a large yellow lab mix of something wearing one of those pinch collars. The dog is between me and my vehicle so I slow my pace and scan for an owner. I don't see anyone outside but don't scan the insides of the vehicle very carefully because it was dark and the dog had most of my attention. I make a wide circle to get around it. We were both on the passenger side of the vehicle. As I'm walking slowly and calmly, the dog circled around the front of my car to the driver side and cam around the back of the vehicle. I'm about 10ft away. It shifts its weight forward, bares it teeth and starts growling and giving a deep bark. So I stop, start to back away slowly. It continues to bark until I get about 15ft. away from it. Then it starts advancing. So, I draw to the two count and I'm thinking, "Please don't make me shoot this dog." Then, from an old, beat up pickup truck across the aisle about 50ft away at my 10'oclock, an older man, exits and calls the dog to him and yells at me for pulling a gun. /shrug. Yep, guess I was in the wrong.
