How Dogs Know When Their Owners Are Upset

You've had a difficult day.

You sit on the couch without saying much, and before long, your dog appears. Maybe he rests his head on your knee. Perhaps he curls up unusually close or simply sits nearby and watches you.

It can feel as though he knows something is wrong.

Dogs can't ask what happened at work or understand every reason you might be upset. But they are remarkably good at noticing changes in the people around them.

Your dog has spent a lot of time learning what "normal you" looks, sounds, and even smells like.

They Watch Your Face

Dogs pay attention to human faces.

They can notice when your usual expression changes. A tense jaw, furrowed brow, tears, or a lack of your normal smile can all provide information.

Your entire body may look different too.

You might move more slowly, sit with your shoulders slumped, avoid eye contact, or stay unusually still.

These changes may seem insignificant to you, but your dog spends a great deal of time observing you.

When familiar patterns suddenly change, he may notice.

Your Voice Gives You Away

You don't necessarily have to cry or raise your voice for your dog to realize that something is different.

Think about how your voice changes when you're frustrated, worried, or sad.

You might speak more quietly. Your sentences may become shorter. Your pitch or rhythm may change.

Dogs don't need to understand every word to respond to these differences.

They regularly use tone, volume, and other vocal cues when figuring out what's happening around them. Your voice can therefore provide another clue about your emotional state.

Dogs Can Pick Up Changes in Your Scent

Your dog experiences the world through a much more powerful sense of smell than you do.

When you're stressed, your body can undergo physical changes. Those changes can affect compounds present in your breath and sweat.

Research suggests dogs can distinguish between human odor samples collected under different emotional conditions.

Your dog isn't thinking, "That smells like a stressful Monday."

But scent may provide information that something about you has changed.

Combined with your expression, movements, and voice, it gives your dog another clue.

They Know Your Routine

Your dog doesn't need scientific knowledge of emotions to recognize unusual behavior.

He knows that you normally walk through the door and greet him enthusiastically. He knows when you usually make dinner, turn on the television, or reach for the leash.

If you come home and immediately lie on the couch without doing any of those things, the difference may stand out.

Dogs are good at learning patterns, especially patterns connected to the people they live with.

Sometimes knowing you're upset may partly mean knowing you're simply not acting like yourself.

Why Some Dogs Come Closer

Once a dog notices that something is different, his response depends on the individual.

One dog may climb onto your lap. Another might bring you a toy. Some become quiet and stay close. Others may give you more space.

A dog approaching you isn't necessarily experiencing your emotions exactly as you are.

He may be responding to your unusual behavior, seeking reassurance himself, or repeating a behavior that has created closeness in the past.

Whatever the reason, the result can still feel comforting.

Your dog may not know why your day went badly.

But he knows you.

And sometimes, that's enough to bring him to your side.
