Excerpt from Dog Info

Dogs have signals for different stuff. Like when they are wagging their tail they want to play or they are excited. Also if they look at you with puppy eyes they are hungry or they want to go outside. When they're angry they show their teeth. They prick up their ears when they're interested in something. They put their tail in between its legs when it thinks it's in trouble.  Those are the signs you need to know about.
