When the dog was running from west to home, his running speed or velocity was 1 m/s which was then decreased to 0 m/s after reaching home. Here (at home) the dog stopped for a while (5 seconds according to the graph), and his velocity was 0 m/s. Then, he started running again to other East direction with velocity -2 m/s (opposite direction).
