My sweet Maddie, rest in peace, finally mastered a grand feat. After many Christmases, we taught her to find her present. On this particular Christmas, I got four identical boxes. In all of them, I put a t-shirt with my husband’s scent on it. In one of them, was a vacuum-sealed package of tennis balls for her. I wrapped them in identical paper. It took her a few directions to snap to it. My husband was using aluminum foil in the kitchen and the sound of it threw off her concentration (so you hear my yelling to my husband in the kitchen). Not only does she find the right box, but she unwraps it, gets her nose into the box to get her present out, and then takes it to her lair (the chair). Enjoy!!!
