We are watching a Chiuaua at our house for a week. Her name is Lilo. She is adorable. However, Olive (our youngest Pug) is so completely jealous of her...now Olive knows how Pugzilla feels. Anywho...this Chiuaua has her own play pen (because she is so tiny, we don't let her run around for fear of stepping on her.) I do not think, however that I could have such a small dog, Pugs, I think are the smallest I could go.
By the way, she has super sharp claws!
She is not much bigger than my mouse.
