Since we only have one Yorkie (or dog for that matter), Sophie doesn't have anyone to play with.  Occasionally she will bite on the cat, but not much anymore.  She has a whole basket full of toys, and occasionally she will pull them out.  This seems to happen around 9:00 pm for some reason.  Otherwise, she does not play with them much.  She won't fetch, and she will only play with us occasionally.  Now that she is six, she rather just lay around where we are.  She does love to go for a walk though.
