The Big Mistake You’re Making With Your Dog’s Behavior

We talk to our dogs, cuddle them like family, and swear they understand us better than some people do. But what if we’re getting them all wrong? According to new research, humans may be terrible at interpreting their dogs’ emotions—even though we think we’re experts. It turns out we’re often distracted by the scene around the dog, rather than paying attention to the most obvious clues: their actual behavior.

We think we know what dogs feel—science says otherwise

It’s easy to assume we can read our dogs like an open book. When my Labrador, Hugo, runs to the door wagging his tail, I think, “He’s excited to go out.” But am I reading Hugo—or just reacting to the context? A study by researchers at Arizona State University suggests we’re mostly guessing, and often getting it wrong.

According to animal behaviorist Holly Molinaro, people rarely focus on a dog’s own body language. Instead, we’re more influenced by what’s happening around them—a treat in hand, a noisy vacuum, or a leash being dangled. We assume how the dog feels based on the situation, not the signals they’re giving off.

The experiment that revealed our blind spots

To test this, Molinaro and psychology professor Clive Wynne showed hundreds of people short videos of a dog reacting to various situations—some good (getting ready for a walk), some less pleasant (a stern voice, or a loud appliance). The twist? They edited some videos so the dog’s emotional display was paired with a different context.

The same tail wag and alert expression, when seen next to a leash, was judged “happy and calm.” But when that identical behavior was paired with the vacuum cleaner, people called it “nervous and agitated.” The dog didn’t change—our perception did.

And when asked what clues they used to judge the dog’s emotion, people rarely picked the situation. They believed they were reading the dog. In reality, they were reacting to the environment.

The problem with projecting our own feelings

Here’s where it gets trickier: we don’t just misread dogs—we overlay our own emotions on them. If you’re in a cheerful mood, you might assume your dog is too. But that’s not an accurate reading of your pet; it’s a reflection of your own state of mind.

Molinaro even tested this with her own dad, who starred in the video clips used in the study. She assumed he’d ace the test. He didn’t. “Even he got it wrong,” she said, suggesting that even dog owners may be blind to these biases.

So what should we do instead?

If you want to really understand your dog, start by tuning out the background noise—literally and figuratively. Stop assuming that your dog is happy because the moment feels happy to you. Instead, take a closer look at what your pet is actually doing. Are their ears up? Is their body relaxed? How’s their breathing?

“Every dog is different,” Molinaro said. What works as a signal for one may mean something else for another. Some dogs wag their tails when they’re nervous. Others growl during play. The best way to understand your dog is to observe them consistently and learn their personal patterns.

It’s a bit like learning a new language. At first, it’s all guesswork—but over time, if you really pay attention, you start picking up on the nuance.

Final takeaway: less guessing, more observing

Dog owners don’t need to become certified trainers to improve communication—but we do need to be a little more humble. Instead of relying on gut feelings, watch your dog closely. Over time, you’ll notice subtle shifts that say more than any context ever could.

And maybe, just maybe, the next time your pup glances up at you with those soulful eyes, you’ll actually know what they’re trying to say. Wouldn’t that be a better bond for both of you?
