Condemning the Appearance of Aggression

Recently, we had a dog arrive at our home for training, and as the owners walked through the front door, our 10-month-old Great Dane, Ripley, started growling and barking from her crate which is nearest to the front door.

My husband immediately stepped in and corrected the behavior.

To someone unfamiliar with her, that moment could have looked pretty alarming. Big dog. Deep bark. Growling. Stiff body language. Uncertainty.

At first glance, some people would immediately label that behavior as aggression.

But here’s the reality: if Ripley had been allowed to approach on her own terms, she likely would have slowly worked her way over, leaned against the guests for affection, and eventually brought them a toy.

Because she’s not an aggressive dog.

She’s a young dog who was unsure of unfamiliar people entering her home.

And honestly? That’s a pretty understandable reaction from an animal.

Sometimes dogs display uncertainty because humans are capable of inflicting serious harm. Dogs are often more afraid of humans than they are of almost anything else. As a trainer, I see this constantly when I walk into homes with nervous or fearful dogs. Families will warn me ahead of time that their dog is “aggressive,” and then I arrive and realize very quickly that the dog isn’t trying to hunt me down or hurt me — they’re terrified and trying to make the scary thing go away by appearing as intimidating as possible.

There’s a massive difference between a dog saying:

“I want to hurt you.”

And a dog saying:

“Please don’t come closer because I’m uncomfortable.”

Unfortunately, a lot of people don’t know how to tell the difference.

When I was about 18 years old, I worked at an animal shelter. One day, staff members were being trained on how to draw blood for heartworm tests, and we were allowed to bring our own dogs in to practice with. I brought my German Shorthaired Pointer, Heidi.

Heidi was one of the sweetest dogs I’ve ever known.

While I worked, I temporarily placed her in a kennel run at the back of the shelter. There was no kennel card on her run because she wasn’t a shelter dog — she was just there with me for the day.

At some point, the shelter manager walked through the kennels, saw Heidi reacting nervously behind the kennel door, and immediately made the comment that the dog needed to be transferred for euthanasia as soon as her stray hold was up.

The problem?

She had no idea who the dog was.

She had no history on her.

She hadn’t handled her.

She hadn’t assessed her.

She had simply watched a frightened dog react to a stranger approaching her kennel and decided within seconds that the dog was dangerous.

I remember laughing because I genuinely thought the manager was joking.

I told her: “That’s my dog. She’s not mean.”

We walked back to the kennel together, and I intentionally let the manager walk ahead of me so she could see Heidi’s reaction first. Sure enough, Heidi barked and lunged at the kennel door. She looked terrifying.

But the second I stepped into view, everything changed.

I opened the kennel door while the manager physically recoiled backward, expecting the worst. Meanwhile, Heidi stood there wagging her tail while I clipped on her leash. Once she was out of the kennel and beside me, she was exactly who she had always been: happy, social, affectionate, and completely safe.

The manager wasn’t reacting to my dog’s actual temperament.

She was reacting to fear-based behavior displayed in an incredibly weird and stressful environment.

And that moment stuck with me for the rest of my life.

Because how many dogs get labeled “aggressive” after less than 30 seconds of observation?

How many fearful dogs are condemned because the people evaluating them don’t fully understand canine body language?

That misunderstanding doesn’t only happen in shelters, either. It happens in homes, veterinary offices, daycare facilities, boarding kennels, grooming salons, and even within the dog training industry itself.

Years ago, when I sought help for my dog Leo, I was told by multiple professionals that he was neurologically damaged, unsafe, and essentially beyond help.

The reality was far more complicated than that.

Leo became deeply insecure about people approaching us after we were physically attacked by someone we thought we could trust. That experience changed both of us. After that incident, Leo started viewing unfamiliar people as potential threats, and because he was a dog, he responded the only way he knew how — by trying to create distance and make people go away before either of us could get hurt again.

People called him aggressive.

People said there was something wrong with him.

People said he couldn’t be fixed.

But Leo wasn’t a bad dog.

He was trying to protect himself. And while I can absolutely say he was trying to be protective of me, I also know he was trying to protect himself too. He learned through experience that humans were capable of causing harm, and after trust had been so severely broken, he started assuming everyone could be dangerous.

That doesn’t excuse inappropriate behavior, but it does explain it.

And understanding the “why” behind behavior matters.

The same misunderstanding happened with Bella, our tiny 10-pound Miniature Pinscher with a bite history. Bella learned very quickly that when she displayed threatening behavior, humans backed away and left her alone. Because people repeatedly ignored her fear, ignored her body language, and pushed her past her comfort level, she eventually learned that escalating her behavior worked.

Now that label follows her everywhere.

People hear “bite history” and immediately assume she’s a dangerous dog, when the reality is that Bella is one of the most affectionate, loving little dogs once trust is established and her boundaries are respected. As her confidence has grown and as she’s learned that not every human interaction is dangerous, her behavior has changed dramatically.

But labels stick.

And sometimes dogs spend the rest of their lives paying the price for humans failing to understand what they were communicating in the first place.

Now, to be absolutely clear: I am not making excuses for dangerous behavior. Truly dangerous dogs do exist, and public safety matters. I’m also not saying fearful dogs should be allowed to bark, lunge, or bite without intervention.

What I am saying is that we need to be incredibly careful before labeling dogs as aggressive when they may simply be afraid.

We need to slow down.

We need to consider the dog’s perspective.

We need to stop treating fear and aggression as if they are automatically the same thing.

Most of the behavior cases I work with are not abnormal dogs. They are dogs trying desperately to communicate discomfort, uncertainty, stress, or fear in the only ways they know how — and humans either miss the signs entirely or punish the communication without understanding it and continue to push the dog in the wrong direction, with no structure, no guidance, and no understanding.

The solution isn’t blind optimism. It isn’t pretending every dog is safe. It isn't simply punishing every indication that a dog is uncomfortable. And it certainly isn’t immediately condemning every fearful animal that displays defensive behavior.

The solution is discernment.

Dog owners, breeders, shelters, rescues, groomers, trainers, veterinary staff, and daycare employees should all have a foundational understanding of canine body language. There are so many free educational resources available today that there’s really no excuse not to continue learning. Being able to understand and identify the difference between stress and malicious behavior comes with experience, but the information is widely available online, at the library, and through many trainers like myself.

Because when we fail to understand what dogs are actually communicating, the consequences can be life-changing.

Sometimes even life-ending.

And sometimes, the dog standing behind the kennel door looking “aggressive” is really just a scared dog hoping someone will finally understand them.
