I would have to say that indoor fetch has saved our sanity on many a bad weather day. She loves to play chase as well with a toy in her mouth. She will come up to us and dare us to take it from her. Of course then the chase is on. She always wins with me.
At night when I think that play time is finally over she will bring one of her toys up on the bed and flop it in my face, wanting me to bring it to life so she can fight with it.

She is a spunky little thing.
