Are there books on dog body language?

Body language is on tv all the time. Are there books on body language of dogs or maybe even cats?

There is reference to reading a cat's tail. Not sure about dog body language. Would be interesting though. My dog tells me a lot through expression. How the head is held, the tail is a good indicator too.

I have seen things about reading cat's tails. There is some body language one can learn about dogs but I have never seen a whole book on the subject.

You can read a lot about your dog. I haven't found a specific book on dog body language though.
