I get his leash and head to the door , and he 's already waiting for me because he saw me getting the leash . We walk down the block , stopping every so often so he can sniff around and see all his favorite sights , then start to head home . On the way home , sometimes we see one of my neighbors who is also walking their dog -- I 'll stop and talk with him for a few minutes while our dogs say hello and play around for a few minutes . After that , we 'll go back to my yard , and he 'll potty before going back into the house . I 'll close the door behind us , then take the leash off his collar before he goes running back into the house , looking for some other fun thing for us to do . Question: After putting the leash on the collar, what did they open? Option1: the book Option2: The door to their home
