Lately I have noticed that every book I seem to buy is about a dog. My favorite is Caroline Knapp/A Pack of Two. I highly recommend this to any dog lover. I have read this book over and over.
I also like Art of Racing in the Rain and Marley and Me. I just bought Merle's Door today and am looking forward to reading it.
I noticed a book on a cat now called Dewy. I think I will read that next!
I really liked the Dogs of Babel. It's about a man who's wife died and the only witness was his dog. He then tried to teach his dog to talk to get it to tell him what happened that day. It's interesting and kind of science-fictiony/weird...but pretty entertaining!
