This is one of the biggest misconceptions in the dog world.
Dogs communicate with us in so many ways their eyes, ears, posture, movement, facial expressions, vocalizations, and yes… their tail.
But a wagging tail doesn’t automatically mean, “I’m happy!”
A wagging tail often tells us that a dog is stimulated or aroused. That arousal could come from excitement and happiness, but it could also come from uncertainty, stress, frustration, fear, or even conflict.
That’s why you can’t look at ONE piece of body language and assume you know what a dog is feeling.
Look at the whole dog.
What are the ears doing?
Is the body loose or stiff?
Where is their weight shifted?
What are their eyes telling you?
What was happening right BEFORE the tail started wagging?
The better you become at reading your dog, the better you become at communicating with them.
