Teaching your dog to wait at a boundary, like the threshold of a door, is not only a useful skill but could also save his life! In Wait at a Boundary: Part 1, KPA faculty member Shelly Brouwer began teaching her dog Bert to wait at an interior doorway using a leash on the ground as a boundary. Shelly clicked and rewarded Bert as he approached the leash. In Part 2 of this series, Shelly waits until Bert pauses at the boundary and inserts the cue “wait.”
