Reading your dog's body language
Your dog talks to you constantly, but with his body, not with words. The golden rule: never stop at a single signal, read the whole picture (tail, ears, posture, gaze, speed). A wagging tail doesn't always mean "happy", and following you everywhere is almost always a sign of healthy attachment.
Why your dog talks with his whole body
The dog is a hyper-social species that co-evolved with us: staying close to you is where he naturally feels good, and he reads you constantly (posture, walking pace, smell). His language is the reflection of how he feels in the moment, never a hidden intent to "dominate" you. By adapting the "strange situation" test for dogs, researchers have shown that he treats you as a secure base: he explores, then comes back to check where you are (Topál et al. 1998). Following you, gazing softly at you, resting his paw on you: these are gestures of connection, not quirks to correct.
The tail: a barometer, not a "happy" button
The tail releases tension, positive or negative. The position sets the tone: neutral and loose = relaxed; high and stiff = a very assertive or alert dog; low or tucked = worry, even fear. The speed tells you the intensity: the faster it is, the stronger the emotion. And the body completes the picture: when the tail AND the hips sway together, that's joy; a tail alone vibrating fast on a frozen body can betray stress or excitement, sometimes just before he acts.
A measured and surprising detail: the direction of the wag matters. A wag more towards the dog's right goes with a positive state, more towards the left with a negative or withdrawn state (Quaranta, Siniscalchi & Vallortigara 2007; Siniscalchi et al., Current Biology 2013). Take it as a tendency, not an absolute rule.
"Why does he do that?": everyday scenes
He follows me everywhere
- A healthy social behaviour in the vast majority of cases: you are his secure base and the source of everything that matters.
- The real test isn't "does he follow me when I'm there?" (nearly all of them do), but "how does he cope when I actually leave?".
- Right up to the toilet: pure togetherness and habit. He doesn't have our sense of privacy, so he comes along with you.
He wags his tail
- An emotion in progress, not necessarily joy.
- A loose tail and hips swaying together = happy; a stiff tail vibrating on a tense body = excitement or tension.
- Worth explaining to children: a wagging tail doesn't mean "you can go ahead".
He stares at me
- Soft gaze, half-closed eyes, a loose body = affection or a request (a walk, a meal): this mutual gaze feeds the bond (Nagasawa et al. 2015).
- A hard, frozen stare, the whites of the eyes showing, often over a bowl or a toy = tension. Don't lean over him, give him space.
He rests his paw or his head on me
- A gesture of contact and of asking, most often learned because it "worked" once.
- A resting head is a gesture of trust and comfort.
- Nothing to correct, unless it becomes intrusive: then teach him a calm alternative rather than telling him off.
Reading his body at a glance
The same sign changes meaning depending on the ones that go with it. These cues are read together, never one at a time.
All is well, he's relaxed
Discomfort: give him space
Read it in context
Refusing a treat he usually loves is one of the most reliable markers of stress: in that case, give him some distance.

Frequently asked questions
Why does my dog follow me everywhere?
Because you are his secure base and the source of everything that matters (walks, meals, play, cuddles). It's a healthy social behaviour in a species that co-evolved with us, not "dominance". The real clue isn't that he follows you when you're there, but how he copes with your absence.
Why does my dog cling to me all the time?
The "clingy" temperament is a character trait, not a flaw. Check his needs first: a dog who lacks activity often clings out of boredom, and real physical and scent-based exercise makes the clinginess ease off on its own. Never try to "un-stick" a dog by telling him off: it creates insecurity, and he clings even more.
What does it mean when a dog wags its tail?
An emotion in progress, not necessarily joy: the tail releases tension, positive as much as negative. A loose tail and hips swaying = happy; a stiff tail vibrating fast on a tense body = excitement or tension. Always look at the whole body before concluding.
Why does my dog follow me to the toilet?
For exactly the same reasons as everywhere else: social togetherness and habit. He doesn't have our sense of privacy, so he comes along. If it bothers you, teach him a "stay" or a "go to your bed" in front of the door rather than shutting it in his face.
How can I tell if my dog is happy?
From the whole picture, never from a single sign: a loose body, a relaxed mouth, a tail swaying with the hips, a soft gaze and blinking. A dog who's comfortable in his own skin explores, comes back to check where you are, then knows how to settle quietly. Be wary of viral "love tests": they're observation games, not measurements.
Why does my dog stare at me?
A soft gaze, half-closed eyes and a loose body, expresses affection or a request (a walk, a meal), and this mutual gaze strengthens your bond (Nagasawa et al. 2015). Tell it apart from the hard, frozen stare, with the whites of the eyes showing, often over a bowl or a toy, which signals tension: there, don't lean over him and give him space.
