Yes. I was out in a field on foot checking some cows. A stray/rogue German Shepherd was out in the field. I tried to chase him off. Fired a shot near him in the dirt. Didn't change his mind, he was coming at me at full speed, hair bristled and meaning business. I empty the BLR 22 LR into this dogs face and chest as it ran full speed. I am not sure how often I hit, but I hit enough. It dropped dead a few feet in front of me. My heart was racing. I thought for sure the dog was going to get me.
