If you love dogs, you'll love Red + Rover. It's my favorite comic strip. I read it every day in the Washington Post.
I love it because Rover is a yellow Lab and because the love that Red has for Rover (and vice versa) captures very well the way I feel about my own yellow Lab, Tango. (And how I hope he feels about me.)
It's a great pick-me-up each day. If your paper doesn't carry Red + Rover, you can see it every day, and even subscribe to have it delivered every day to your email in-box.
