More: They are a very special part of our family. My female, Coco, is so loving and always ready for attention. Our male, Paco, is so mellow and laid back. These two are some of smartest dogs I've ever had. They learn to do some stuff that I didn't think dogs could do, like open doors. My husband was even able to teach Coco how to smile. Paco's most beloved possessions, besides his collar, is his chuck-it ball. He loves to play ball. He can go non-stop if you let him. If we don't play ball with him, he will play by himself. He has learned how to kick it around, like a soccer ball, with his paws. He will kick it and pop it with his paw to make it bounce. Very self entertained. Coco's favorite game is keep away. Unlike Paco, if you throw her ball to play fetch, she will go fetch it but will not bring it back. She is a nosy girl. She loves to look through the cracks in the fence. She will sit and watch people through those cracks. She loves sticks and rocks.
