Brian explains the importance of being able to read the visual cues of your dog's body language so you know what he's thinking and then decide if and how you need to address his forthcoming behavior. Ears and tail up? He's probably seen something that interests or excites him. It could be a squirrel in the next yard or it could be your friend walking towards you. Either way, it's a good idea to know what he's thinking so you can predict his behavior. It's not rocket science—just look, and you'll KNOW YOUR DOG!
