A bull broke loose from a local farm and then traveled onto our land to graze. When I walked out from the front door and walked into our field unknowingly, I laid eyes on the bull I was very surprised to see such an animal. I was already a sizable distance away from the house and probably could not run back. The bull was very aggressive and appeared as if it wanted to charge me. Sparky next to me gave chase to the bull across the field as it fled from the bark of Sparky.
