How do I read my dog's body language?
Read a dog in four cues and never on one alone: ears, eyes, tail, posture. A single wagging tail says almost nothing — a high, stiff tail with a closed mouth and forward weight is a very different dog from a low, loose sweep with a soft open mouth. Take the four together, then ask the more useful question: is this different from how they usually look?
What to look at
| Cue | What you see | What it points at |
|---|---|---|
| Ears | Forward and loose | Interested, taking something in |
| Ears | Pinned flat back against the head | Frightened or appeasing — give space |
| Eyes | Soft, blinking, whole eye relaxed | Comfortable |
| Eyes | Whites showing at the side (whale eye) | Wants out of this moment |
| Tail | Low, wide, loose sweep | Friendly, unguarded |
| Tail | High and stiff, only the tip moving | Aroused, not necessarily friendly |
| Posture | Weight even or leaning in | Settled |
| Posture | Weight shifted onto the back legs | Ready to leave — tolerating, not enjoying |
When to call a vet instead
- 🩺 Sudden change from how they normally hold themselves, with no change at home
- 🩺 Hunched back with the head carried lower than the shoulders
- 🩺 Panting at rest, in a cool room
- 🩺 Stops doing something they always used to do — greeting you, jumping for the leash
Questions people ask
Does a wagging tail mean a dog is happy?
No. A wag only tells you the dog is aroused. A low, wide, loose sweep usually is friendly; a high, stiff tail with just the tip flicking is an aroused dog that may not want contact. Read the tail together with ears, eyes and posture.
What is whale eye in dogs?
Whale eye is when you can see the whites at the side of a dog's eye, usually because they are holding their head still and looking away with the eyes only. It generally means the dog wants the current situation to stop. It is one of the clearest 'please give me space' signals and is easy to catch in a photo.
How can I tell if my dog is tolerating something or enjoying it?
Look at where the weight is. A dog that is enjoying contact leans in or stays even. A dog that is tolerating it keeps its weight on the back legs, often with a closed mouth and a still tail — physically present, ready to leave.
