Dogs have shared their lives with humans for over twelve thousand years, yet we still misunderstand them more often than we’d like to admit.

While they might be experts at reading our emotions, understanding their body language and the subtle signs they use to communicate can be tricky. To make matters worse, countless common myths about dog behavior continue to circulate.

Is a wagging tail always a sign of happiness? Does my dog growling at me mean they hate me? Do canines feel guilty when they misbehave?

In this post, we’re busting up some of these myths. Here are 10 common misconceptions about dog behavior and what they really mean.

1. Tail Wagging Always Means Happy

As a pet parent, you’ve probably heard the popular belief that a wagging tail always signals happiness. Perhaps you’ve come to believe it as well.

But your furry friend’s tail is much more nuanced than that!

A wagging tail indicates emotional arousal, ranging from excitement to fear or even aggression. For instance, a tail wagging high and fast could signal unease, while slow, gentle wags may indicate curiosity.

To truly understand your dog, observe their whole body—their ears, posture, and facial expressions add context to what that tail is really saying.

2. Eating Grass Means They’re Sick

Many pet parents worry that their dog munching on grass signals health issues, but this common belief doesn’t tell the whole story.

Sure, grass can sometimes act as a natural antacid to soothe an upset stomach, but it’s not always tied to sickness.

Sometimes, your furry friend might simply enjoy the taste, especially during spring and summer when the grass is fresh.

This seemingly troubling behaviour may cause concern, but as long as the grass is free of harmful chemicals and your dog is healthy, there’s no need for alarm.

3. Growling During Play Means They’re Bad Sport

Hearing your canine friends growl during a game of tug-of-war or while wrestling might seem alarming, but it’s not always a sign of aggression.

On the contrary, this playful communication helps build trust and strengthens your bond with your furry companion!

Animal behaviorists call it “play growls” when dogs growl in a friendly fashion during fun interactions.

This type of growling often indicates excitement or happiness, not hostility. You might even notice your dog growl softly during a belly rub or snuggle session.

4. Playing Tug Encourages Aggressive Behavior

The idea that playing tug-of-war leads to aggression is a popular misconception. Research shows no evidence linking the game to increased aggression toward people or other dogs.

In fact, tugging is a great way for your dog to practice natural behaviors, releasing excess energy, and reducing destructive behaviors like chewing.

When played correctly, tug-of-war can strengthen the bond between you and your dog while boosting their confidence. Still, you may want to teach commands like “drop it” to keep the game safe and prevent overstimulation.

5. Dogs Feel Guilt With Their Misdeeds

When your dog cowers with ears back and tail tucked after chewing your shoes, it might seem like they know they’ve done something wrong.

However, experts suggest this behavior is more likely an appeasement gesture. Dogs don’t experience guilt the way humans do.

Instead, their negative association with their actions comes from past experiences—like being scolded after making a mess.

The classic “guilty” look is often a response to your cues, such as scolding, rather than an understanding of their misdeed. Dogs may also avoid eye contact to prevent further confrontation.

6. Barking Canines Are Always Threatening

One of the most widespread myths about canines is that when they’re barking, it’s always threatening, but this isn’t necessarily true.

See. barking and growling are distance-increasing behaviours. They’re your dog’s way of creating space and reducing anxiety when they feel unsafe.

Many dogs use barking to communicate their discomfort, especially if they’re unable to use subtler signals.

While some dogs may bark protectively, more often than not, they’re simply expressing anxiety and trying to drive away something they perceive as threatening.

7. Dogs Want to Dominate Others

The idea that dogs are trying to dominate their owners is based on the dominance myth that has long been debunked.

Many behaviors, like jumping or pulling on a leash, have been incorrectly attributed to a dog’s need to assert power. In truth, canines simply act on what works for them and need clear training and boundaries.

8. They Disobey Commands Because They Want To

If your dog ignores a command, it’s rarely out of defiance, so you shouldn’t take it to heart. Chances are, they don’t fully understand what’s being asked or are too distracted to comply.

Dogs aren’t great at generalizing, so mastering a skill like obeying a “sit” command in your quiet kitchen doesn’t mean they’ll do the same at a busy park.

Inconsistent or insufficient teaching can also hinder learning.

Most canines need proper training and positive reinforcement. Help your dog succeed by practicing commands in various environments and keeping expectations realistic.

9. Pups Love It When You Hug Them

We know it’s almost impossible to resist hugging your adorable pet to express affection, however, dogs often feel differently.

Most pups value their personal space and can find hugs uncomfortable or even threatening. This stems from their instinctual behaviors—pinning down is often a sign of dominance or aggression in the canine world.

Some dogs may tolerate or even enjoy the occasional embrace. Still, the safer and more respectful way to show your love is through gentle pets, belly rubs, or playing their favorite game.

It’s another common misconception that dogs act out of spite when they chew furniture or have accidents indoors. But although it may look and feel that way, canines aren’t exactly the creatures to feel spite.

Dogs don’t develop destructive behaviors to “get back” at their owners. These emotions simply don’t exist in their genetic makeup.

Chewing, soiling, or tearing up items are often the result of anxiety, boredom, or a lack of exercise and stimulation.

Your furry friends rely on routine and enrichment to stay happy and well-behaved. Addressing these needs can help prevent messes and ensure your furry friend feels secure and engaged.

Understanding your pup’s true needs and behaviors can strengthen the bond you share and create a happier, healthier environment for your furry friend.
