The dog’s yawn is often used as a calming signal in the language of dogs. It’s a way of saying, I’ve had enough and my patience is running out. For example, in a training session, your dog may yawn to deal with frustration and to give himself a mental break. The next time your dog yawns while you’re training him, try showing him you got the message by reducing your intensity or changing your approach.
A yawn may indicate anticipation or stress, too. Your dog may yawn repeatedly when he’s waiting in the vet’s office as a way of dealing with nervousness. Sometimes dogs yawn in anticipation of something enjoyable, such as a walk-this is a way of controlling his enthusiasm. The simplest way to understand the real meaning of the gesture is to look at the situation.
Of course, there are times when a yawn is, well, just a yawn. If he yawns while stretched out comfortably on his bed, he’s probably just tired. If you’re training or playing with your dog and he yawns, he may be asking for a little break.
