My shepherd steered me across the road around a copper head 1 night. I never used to walk with a flash light since we had street lights every 200ft down the street.
She was pretty insistent that we cross the road. Being on a dead end street with little traffic we tended to wander anyway.
After we got down the street a little further I happened to look back and that's when I saw the copperhead stretched out by the ditch on the other side of the street.
She was told she was a good girl, and got extra treats. I also pay very close attention to her now when she starts getting insistent that we avoid a certain spot. Flash light comes out and I start inspecting things really closely.
