Woof!
My favorite activity is eating, because, well, I'm a Lab... But after that, my second favorite thing to do is play fetch with a nice yellow tennis ball. I could run all day and never get tired of chasing that ball...
I also love going on long walks, saying "Hi" to people, and chasing all the squirrels in my backyard. I never catch them and I'm not sure what I would do with one if I did...
