The Language of Dogs DVD, by Sarah Kalnajs. There is no better way to learn to read the body language of dogs than by seeing dogs in action. However, in real life, sometimes the signals happen so quickly we miss them. You will learn to catch more of these signals in daily life if you are practiced at spotting them. This set of DVDs gives you a great variety of dog body language with real examples of each that you can watch over and over again. If you are serious about learning to better read dogs, I recommend this set of DVDs.
