I noticed in all the past pictures of Paris with her new puppy that it's tongue is always sticking out a little. My Chihuahua is the same way and in fact her tongue dries out around the edges and turns brown at times.
I think this is the firs picture I've see of Paris with a dog that she has shown an interest in or a playful side. I think she has just been "Yorkietized" like the rest of us, so I won't be surprised if she get's another Yorkster kid.
