Back in my racing days a standard Th night route took us up a long gradual rural mountain climb and a big German Shepherd would start barking when we were many houses away then charge out and chase us up the hill. This went on for many months, then one day.....no Shepherd. We found out he had been hit by a car.

Well, a number of weeks later we hear the familiar barking as we approach, sure enough it was the Shepherd, charging at us and chasing us on three legs! We almost felt like we needed to slow up to make it more of a contest for the poor guy.
