Good things come in small packages, right? Consider TicTac. She is a Chihuahua, just over four pounds, tiny like the candy for which she's named and every bit as sweet. She is affectionate and she enchants everyone who gets to meet her. She’s a shoulder dog, with a distinct preference for the right shoulder. (If you put her on your left, she will squirm until she makes it over to the right.) She has a knack for making whoever is holding her feel like the center of the universe, which probably explains how she retains her supremacy.
