Dog Body Language — Tail, Ears, and Posture

A dog’s tail is one of the most visible indicators of their emotional state, but it is also one of the most commonly misread. Here is what to look for:

Tail Height

• High and stiff — confidence, alertness, or potential aggression. The dog is highly aroused
• Neutral (level with the back) — relaxed, comfortable
• Low or tucked between the legs — fear, anxiety, or submission

Tail Movement

• Broad, loose wag — friendly, relaxed excitement
• Fast, stiff wag — high arousal, not necessarily friendly. Approach with caution
• Slow wag — uncertainty, assessing the situation
• Helicopter wag (full circular rotation) — extreme happiness, typically seen during greetings

Remember that tail language varies by breed. A Greyhound’s natural tail position is low, while a Husky carries theirs curled over the back. Learn your own dog’s neutral baseline and watch for deviations from it.

Ears

• Forward and pricked — alert, interested, or aroused
• Relaxed and slightly to the side — calm, content
• Pinned flat against the head — fear, anxiety, or submission
• One ear forward, one back — conflicted, unsure

Posture

• Weight forward, leaning in — confident, engaged, potentially confrontational
• Weight back, leaning away — uncertain, nervous, wanting distance
• Play bow (front legs down, bum up) — invitation to play. One of the clearest friendly signals
• Freezing or going very still — a serious warning sign. The dog is making a decision and may escalate
• Rolling onto back — can be relaxed submission OR a defensive position (watch the rest of the body)

A dog that is simultaneously showing a high stiff tail, forward ears, closed mouth, and forward weight distribution is displaying a cluster of signals that demands caution.
