My aunt is looking for a female Yorkie that's not a baby, but she still wants the pup to be playful. Play with toys and such. About what age do you think they grow out of it? Do you think a two year old would still be playful? I mean, Baby is 9 months and is still playful obviously.

I'm just wondering at what age do they get tired of that? Any comments, stories, etc. will be appreciated.
Thanks!
