Your dog speaks to you every single day—but are you listening? A recent 2025 veterinary behaviour study found that 68% of dog owners miss critical body language signals that indicate anxiety, fear, or discomfort in their pets. The Royal Veterinary College’s latest research shows that early recognition of these signals can prevent behaviour problems before they escalate. In this article you’ll discover 12 often-overlooked signals your dog uses to communicate, including one stress sign that vets say is desperately misunderstood. By the end, you’ll understand your dog’s inner emotional world—and why that stiff tail wag might actually mean your pup is worried, not happy.
1. The Whale Eye (White Sclera Showing)
When you see the whites of your dog’s eyes—especially the area below the iris—this is called “whale eye” and it’s a red flag. Your dog is uncomfortable, anxious, or assessing a potential threat. This happens when dogs are stressed but trying to stay still, perhaps during a vet visit or when a stranger approaches.
2. Lip Licking and Mouth Tension
Rapid lip licking when there’s no food around signals anxiety or nervousness. Paired with a closed or tight mouth, your dog is expressing stress. You’ll often notice this during thunderstorms, fireworks, or when your dog is unsure about a situation.
3. Ears Pinned Back Flat
Backward-facing ears don’t always mean submission—context matters. Softly pinned ears during play is normal, but ears pulled extremely flat against the head signal fear or anxiety. A dog showing this combined with whale eye is genuinely frightened.

4. The Stiff, Slow-Motion Tail Wag
Here’s the signal vets say most owners misread: a slow, stiff tail wag is NOT happiness. A relaxed happy dog wags their entire rear end with a loose, fluid motion. A stressed dog does what’s called a “half wag”—the tail moves but rigidly, often held lower than usual. Max, a Labrador from Manchester, nearly bit a visitor because his owner didn’t recognise this signal as a warning, not a greeting.
5. Play Bow Confusion
A play bow (front legs stretched, rear in the air) usually signals “let’s play.” But context is everything. If your dog does this repeatedly and then immediately walks away or shows tension elsewhere in their body, they may be trying to defuse a tense situation rather than initiate play.
6. Yawning When Not Tired
Dogs yawn when they’re genuinely sleepy, but they also yawn as a stress response. If your dog yawns during training, vet visits, or social situations, they’re signalling mild anxiety. This is one of the earliest stress indicators before more serious behaviours emerge.
✅ Expert Tip
Create a “body language journal” for one week. Write down what your dog’s body looks like during different activities (meals, visitors, walks, alone time). You’ll quickly spot patterns in their anxiety triggers and can proactively manage stressful situations before they escalate.
7. Piloerection (Hackles Raised)
Raised hair along the spine (hackles) indicates arousal—but not necessarily aggression. Your dog could be excited, anxious, or uncertain. Watch the rest of their body: a raised hackle with a loose stance and play bow means excitement, whilst raised hackles with stiff posture and whale eye signals fear or frustration.
8. Avoidance Eye Contact or Hard Staring
Many owners think direct eye contact shows trust and affection. Dogs do offer soft eye contact to their favourite people, but prolonged, intense staring from your dog at another person or animal is a warning sign. It can precede reactive behaviour. Similarly, a dog who deliberately looks away or avoids your gaze might be anxious or trying to de-escalate tension.
9. Freezing or “Statue Mode”
A dog who suddenly goes rigid and completely still isn’t calm—they’re overwhelmed. Freezing is a stress response before fight or flight. You’ll notice shallow breathing and dilated pupils. This often happens with anxious dogs encountering new people, animals, or environments.
10. Yawning, Turning Away, and Lip Licking Combined
When your dog does multiple signals in sequence (yawn, then turn their head away, then lick lips), they’re actively trying to calm themselves down. This “calming signal” cluster shows your dog is stressed and self-soothing. It’s time to remove them from the situation or reduce stimulation.
⚠️ Warning
If your dog shows persistent whale eye, lip licking, freezing, or avoidance in everyday situations, or if these behaviours are followed by reactive outbursts, consult your vet or a qualified behaviourist. Chronic stress can lead to aggression, destructive behaviour, and health issues. Contact your vet immediately if you see signs of excessive stress that don’t improve with environmental management.
11. Raised Paw or “Softing” Behaviour
A dog placing their paw on you or your face isn’t always affection—it can be appeasement. An anxious dog might do this to say “please don’t be upset with me.” Paired with whale eye or a tucked tail, this is a clear anxiety signal rather than a bid for attention.
12. Tail Position: The Complete Picture
Tail language is complex. A high, loose wag means joy. A tail tucked between the legs shows fear. A tail held level with the spine (neutral) during interactions is a dog who’s confident. A tail held high and stiff (without wagging) can indicate potential aggression or dominance. Never read the tail in isolation—combine it with ear position, mouth tension, and body posture.
Why Context and Combinations Matter
Single signals can be misleading. A yawn might just mean your dog is tired. Ears back during a play session is normal. But when multiple signals cluster together—whale eye + ears back + lip licking + stiff tail—your dog is telling you they’re anxious and need help. The 2025 RVC study emphasises that dogs communicate through combinations, not individual behaviours in a vacuum.
Understanding your dog’s body language is one of the most powerful tools you have as an owner. That slow wag you thought meant happiness? It might be anxiety. That “calming signal cluster” you didn’t recognise? It’s your dog asking for help. The good news: once you start watching for these 12 signals, you’ll spot them everywhere, and you’ll be able to support your dog before stress escalates into behaviour problems. Have you noticed any of these signals in your own dog, and did you realise what they meant? Start observing this week, and you’ll transform your relationship with your pup.
