6. “My Tail Wag Is a Whole Language — and You Only Know One Word”

Wagging right means positive feelings. Wagging left means anxious or unsure. High and stiff means alert. Low and fast means nervous. Mid-level relaxed means calm. Most owners only catch the basic “wag = happy” version. Watch the direction and height next time, not just the speed. The next one explains a behavior almost everyone gets wrong.
