⚠️This is probably one of the most misunderstood pieces of canine body language.
We’re taught from childhood:
🤦♀️Dog wagging tail = friendly, happy dog.
But that simply isn’t always true.
➡️A tail wag tells us that a dog is emotionally aroused and engaged with what’s happening. What it doesn’t tell us, on its own, is whether that emotion is positive.
A dog may wag their tail because they’re:
🐾 Happy
🐾 Excited
🐾 Anxious
🐾 Uncertain
🐾 Frustrated
🐾 Conflicted
🐾 Highly alert
🐾 Over-aroused
🐾 Preparing to react
➡️And this is why looking at one body part in isolation can be dangerous.
Imagine two dogs.
🐶 Dog A:
Their tail is making big, loose, sweeping movements. Their whole backside is wiggling. Their body is curved and relaxed, their face is soft and their movements are loose.
Now compare that with…
🐕 Dog B:
Their tail is high and wagging rapidly in short, tight movements. Their body is stiff. Their weight has shifted forward. Their mouth has closed. Their eyes are fixed on something.
Both dogs are wagging their tails.
⚠️But they may be communicating VERY different things.
This is also why statements such as:
“But his tail was wagging!”
can sometimes be heard after a dog has growled, snapped or bitten.
The wag was noticed.
The rest of the dog wasn’t.
When reading canine body language, look at the whole picture:
👀 Are the eyes soft or staring?
👂 What are the ears doing?
👄 Is the mouth relaxed or suddenly tightly closed?
🐕 Is the body loose and curved or stiff and upright?
⚖️ Is the dog’s weight moving backwards, forwards or remaining neutral?
🦴 Where is the tail being carried?
💨 Is the wag broad and loose or short, fast and tight?
And most importantly…
🌎 What is happening in the environment at that moment?
✅Body language only makes sense in context.
Dogs are communicating with us constantly, often long before they feel the need to bark, growl, snap or bite.
We just need to learn how to listen.
❤️ A wagging tail isn’t a green light to approach a dog.
Read the whole dog, not just the tail.
