Penny might have to nudge me a bit harder if she wants to go for a walk, because I've come across an addictive little doggie game.
It's here. I read about it in an email from my local library's Web 2.0 site.
It loads quite slowly but it's fun to help the little dog get the bone. (Don't click on the advertisement for Bubble Buster that comes up while you're waiting , if you want to play the doggie game.)
