I've been working too much and spending too much time taking care of the invalid dog, who sure is bundle of energy for such a lame beast. She will pace around the house, falling down here and there, for an hour or two, until it is time for her breakfast at 4 am, after which she (and I) go back to sleep.
She gets a lot of dog cookies. We might be on our last box of them, but I've thought that for the last 15 or 20 boxes. She can't do it like Waldo's dog, but she will go after a cookie at top speed, such as it is. She can mostly see where the cookies go, but I wouldn't hold my thumb out too close to her when she is thinking there still might be a cookie around some where.
