How many times has this happened to you?
You're out walking your dog when a complete stranger walks up smiling and says:
"Oh, don't worry — I'm a dog person!"
"All dogs love me!"
Before you even have a chance to respond, they're reaching toward your dog, leaning over them, or putting their face right in your dog's face.
Then your dog growls. Maybe even snaps.
Suddenly people are looking at you like you have a dangerous or aggressive dog.
The reality is almost always very different.

What's Actually Happening
Most of these people mean well. They simply don't understand that they have just invaded your dog's personal space — and completely ignored the signals your dog was giving them.
In my years working as a certified shelter dog specialist and the official trainer for multiple South Florida rescues — including UFAR Animal Rescue, One Dog at a Time Rescue, POPO Pit Bull Rescue, and Chesed Dog Rescue — this scenario comes up constantly with the dogs I work with.
Dogs, just like people, have boundaries.
Not every dog wants to be touched by a stranger.
Not every dog enjoys someone reaching over their head.
Not every dog is comfortable with someone putting their face inches from theirs.
And adopted dogs, rescue dogs, and dogs with difficult histories are especially vulnerable to this kind of uninvited interaction — because their threshold for feeling safe is often much lower than the average dog.
When those boundaries are ignored, dogs communicate the only way they know how.

A Growl Is Not Aggression. It's Communication.
I want to be very direct about this — because it's one of the most important things I teach every client I work with across Broward and Palm Beach County.
A growl isn't usually the sign of a bad dog.
It's your dog saying: "You're making me uncomfortable. Please give me some space."
The problem is that most people ignore those warnings — or don't recognize them until the dog feels it has no other option but to escalate.
And here's the part that breaks my heart as a trainer: many owners actually correct their dog for growling. They're embarrassed. They say "no"
or pull the leash or apologize to the stranger.
But punishing a growl doesn't make the dog feel safer. It simply removes the warning signal. You end up with a dog that no longer growls before it bites — because it learned that growling leads to punishment.
Removing the warning sign doesn't remove the fear that created it.

Your Most Important Job — Being Your Dog's Advocate
As I tell every client I work with — your job as your dog's owner isn't just to hold the leash.
It's to be your dog's advocate.
That means it's okay — actually it's essential — to politely tell a stranger:
"Please don't pet my dog."
"She's in training."
"He needs a little space."
Your responsibility isn't to protect a stranger's feelings.
It's to protect your dog and set them up for success.
Every positive interaction builds trust.
Every situation where your dog feels trapped or overwhelmed chips away at that trust.
The more your dog learns that you will step in and protect their space — the less they feel the need to protect themselves.
And that shift — from a dog constantly on guard to a dog that trusts its owner to handle the world — is one of the most powerful transformations I witness in my work with reactive and anxious dogs throughout South Florida.

Sometimes the Best Training Isn't Training
One of the things I emphasize most in my in-home sessions is this:
Sometimes the best thing you can do for your dog isn't asking them to tolerate uncomfortable situations.
It's preventing those situations from happening in the first place.
Management isn't failure. It's strategy.
Crossing the street to avoid an oncoming dog isn't giving up — it's setting your dog up to succeed by keeping them under threshold. Telling a stranger not to pet your dog isn't being rude — it's being a responsible owner who understands what their dog needs.
Being your dog's advocate isn't about being difficult.
It's about being the calm, confident leader your dog needs you to be.
Your dog is counting on you to keep them safe. And when they finally know you've got their back — they spend far less time feeling like they have to defend themselves.
That's when the real transformation begins.

Frequently Asked Questions
Why does my dog growl at people who are just trying to be friendly?
Because from your dog's perspective, a stranger reaching over their head or putting their face close to theirs is not friendly — it's threatening. Dogs communicate primarily through body language and space. When a human ignores those signals and invades personal space, the dog communicates discomfort the only way it knows how. The stranger's intention doesn't change what the dog experiences.
Should I correct my dog for growling at strangers?
No — and this is critically important. Punishing a growl removes the warning signal without removing the fear that caused it. A dog that has been corrected for growling will often stop growling before biting — which is significantly more dangerous. The goal is to address what's making the dog uncomfortable, not silence its communication.
My dog has already snapped at someone. Is it too late to fix this?
No. Snapping is almost always a communication failure — the dog's earlier signals were missed or ignored until it felt it had no other option. With the right approach, most dogs that snap out of fear or discomfort can learn to feel safe and respond very differently. The key is understanding what's driving the behavior rather than simply trying to suppress it.
How do I tell strangers not to touch my dog without being rude?
Simply and directly. "Please don't pet her — she needs her space" or "He's in training, thank you" are completely appropriate. Most reasonable people will respect this immediately. You don't owe anyone an explanation and you don't need to apologize for protecting your dog.
My dog is fine with some people but reacts badly to others. Why?
Dogs read body language, energy, and movement patterns constantly. Someone who approaches confidently and calmly from the side is very different from someone who leans over, makes direct eye contact, or reaches from above — all of which dogs can perceive as threatening. Your dog isn't being random. It's responding to very specific signals that humans often don't even notice they're giving.
Is this something that can be fixed through training?
Yes — in most cases significantly and sometimes completely. What I work on with reactive and anxious dogs throughout Broward and Palm Beach County is rebuilding the dog's emotional association with triggers — helping them learn that the world is safe and that their owner will protect them. When that trust is established, reactive behavior typically diminishes dramatically because the dog no longer feels it has to manage the world on its own.

Is Your Dog Struggling With Reactivity or Anxiety Around People?
If your dog growls, snaps, or makes every public outing stressful — you're not dealing with a bad dog. You're dealing with a dog that hasn't felt safe enough to respond any other way yet.
As a certified shelter dog specialist and the official trainer for multiple South Florida rescues, I specialize in exactly these dogs — the reactive ones, the anxious ones, the ones other trainers said were too difficult.
I work with you and your dog together, in your home and your real neighborhood, building the trust and communication that makes lasting change possible.
