Imagine you live in a house with a backyard. The door to the backyard is in your family room. You let your dog Felix out into the backyard a few times a day. You decide you would like to teach Felix to bump the doorknob on the back door with his nose before you let him outside. Currently, whenever Felix wants to go outside, he walks around the family room and often walks past the back door. Describe how you will use shaping to teach Felix to bump the doorknob with his nose. Think about using a clicker to shape Felix’s behavior.
