I have two Yorkies, when I give each one of them a bully stick, my older one (Milou) wants both of them. So she takes a noisy toy, she gets on the sofa and drops it on the floor. My younger one (Jean) listens to the noise and goes to see what it is leaving her bully stick alone. So Milou goes and gets Jean's bully stick.
That's why I love Yorkies,
Maria
