Yes I give anyone walking a powerful dog a wide berth.
Again when I was a kid I was walking my grandads dog. It was a small,daft, soft as shit thing totally harmless. Suddenly it bolted across the road pulling the lead out of my hand and had some poor bloke pinned against a hedge growling and barking. He was petrified and I was in shock. A bloke came out of the house and between we pulled it away and I dragged it home. It was totally out of character. Bizarre and shows how unpredictable animals can be.
