Signs of Stress in Dogs
Stress signs to look for include whale eye (when dogs reveal the whites of their eyes), tucked ears, tucked tail, raised hackles, lip-licking, yawning, and panting. Your dog might also avoid eye contact or look away. This is most commonly seen in a dog that seems “guilty.” However, the pup is actually reacting to your voice and body language and thinks something must be wrong.
Don’t rely solely on body language. Also, some dogs raise their hackles when they are overstimulated or excited, not necessarily when they are stressed or anxious.
