Showing Discomfort
As much as yawns express comfort and security they do have an additional meaning. When a dog publicly yawns it can mean that they are really overtired and are longing for that much-deserved nap. Being on the lookout of this behavior when your dog is in an unfamiliar place is truly a must due to it potentially meaning they are anxious.
Tilting Their Heads
Many people, we may be amongst them, speak in a higher pitch when it comes to talking to their dogs. Your dog may often tilt their head and make out as if they are trying to understand you but they are actually masters of responding to body language and vocal cues. Dogs internalize everything from instructions to criticisms. They are so smart that they may even recognize words and may possibly be waiting for those that result in treats and walks. An additional theory suggests that they do that for better listening comprehension.
