While the following behaviors are typical of a stressed dog, they must be looked at in context to know whether they're stress-related or caused by some other stimulus.

Interpreting Dog Stress Behaviors

Rapid, shallow or deep, forceful panting

A Stress panting is presented with the lips pulled back in a wide "grin" causing deep wrinkles around the eyes and forehead.

Increased urination or defecation

Stressed dogs will often urinate or defecate in an inappropriate area even though they're fully housebroken.

Vomiting or diarrhea

The dog's digestive tract is frequently the first bodily function to react to stress.

Yawning

Yawning is one of the most common signs of stress. A stress yawn will be more pronounced than a sleepy yawn.

Avoidance

A stressed dog will often turn away or shy away from us when they are stressed.

Shaking/shivering

Stress will frequently cause the dog to shiver or shake even though they may not be cold or wet.

Confusion

A dog will often present signs of confusion or abnormal behavior when stressed. Be cautious when interpreting this symptom as it can also be a sign of a seizure or diabetic hypoglycemia.

Whining or growling

Vocalization is very typical in a stressed out dog and is a sign of heightened anxiety.

Stretching

Stretching is the dog's way of relaxing muscles tightened by a stressful situation.

While not an exhaustive list...

these are just a few of the signs that can help you recognize when your dog is stressed.
