“My dog bit someone. Now what?”

This is a call I’ve gotten many times over my years as a dog trainer, and lately I’ve had several conversations that have reminded me how differently people define the word bite.

Sometimes the owner is terrified and convinced their dog is now dangerous. Other times, I hear, “It wasn't really a bite,” “He barely broke the skin,” “It was just a nip,” or “He's still a puppy.”

The truth is usually somewhere in the middle. I don't want you to panic because your dog used their teeth, but I also don't want you to minimize it. Your dog just gave us some important information, and we need to figure out what they're telling us.

Was it puppy mouthing or a bite?

Puppies use their mouths. A LOT. They grab hands, clothes and ankles. They get overtired and turn into tiny land sharks. Normal puppy mouthing can hurt, and those ridiculously sharp puppy teeth can even scratch or puncture skin accidentally.

So I don't decide whether something is puppy mouthing or a concerning bite simply by asking whether teeth touched or broke skin. I want to know what was happening when the dog used their mouth.

Was your puppy bouncing around, grabbing your sleeve, a toy and everything else within reach? Or did they become still when someone reached toward their food and then bite? Were they being handled? Startled while sleeping? Trying to get away? Guarding something? Did they freeze or growl first?

The context matters.

And there's no magical birthday where puppy mouthing suddenly becomes a bite. What I want to see is that normal puppy mouthiness is decreasing as the dog matures.

A six-month-old grabbing a sleeve during an overexcited play session is very different from a six-month-old biting when someone tries to take something away. That's why instead of asking, “Is my dog still young enough for this to be normal?” I'd rather ask, “Why did my dog use their mouth in this situation?”

Breaking skin matters—but it isn't the whole story

I often hear, “It wasn't really a bite because he didn't break the skin.”

Breaking skin absolutely matters, and an injury should be taken seriously. But it isn't the only thing I look at. A dog can make contact without breaking skin, snap and miss, or give several warnings before escalating. All of that gives us information.

On the other hand, a puppy can accidentally scratch you with a needle-sharp tooth during play and technically break the skin.

This is why I want the whole picture: What happened? What came before it? What was the dog's body language? How much damage was done? Has anything similar happened before?

Have we started to normalize biting?

I think this happens more than people realize.

Maybe you grew up with a dog who would bite if you touched his feet, and everyone just knew not to touch his feet. Maybe your family dog guarded his food, so everyone stayed away while he ate.

And when you work around dogs in rescue, shelter, veterinary or training environments, you may regularly see behavior that would be very concerning to the average pet owner. Over time, your definition of “normal” can change.

I'm not saying that as criticism. I've worked with behavior cases for years, too. We naturally adapt to what we're around.

But common doesn't necessarily mean acceptable.

Understanding why a dog bites is incredibly important, and sometimes I can completely understand why a dog reacted the way they did. But understanding the behavior isn't the same as excusing it.

Maybe someone grabbed your dog, ignored their warnings, reached toward their food or cornered them. I absolutely want to know that because it helps us understand why the bite happened.

But I can say, “I understand why this dog felt threatened,” and still say, “We need to make sure this doesn't happen again.”

So what do you do after a bite?

First, separate your dog from the situation and make sure everyone is safe. Don't bring the dog back over to see if they're “okay now,” and don't recreate what happened to test them. If your dog bit when someone reached toward their bowl, we don't need someone else to reach toward the bowl to see what happens.

We already got information. Let's use it.

Once things have settled down, write down what happened while you remember it. What happened immediately before the bite? What was the person doing? What was the dog doing? Was food, a toy, handling, sleep, restraint or another dog involved? Could your dog move away? Did they freeze, turn away, growl or show other signs you didn't recognize at the time?

Very often, when someone tells me a bite happened “completely out of nowhere,” slowing the situation down tells us a lot more.

If there's an injury, the person should get whatever medical care is appropriate. You'll also want to find out whether there are any steps you're required to take where you live. Requirements vary, so check with the appropriate resources in your area, which may include your veterinarian, local health department or animal control agency.

And even if the person says, “I'm fine! Don't worry about it,” we still don't ignore the behavior. Whether someone makes a complaint doesn't change what happened.

Manage first. Then teach.

This is where my Allow, Manage, Teach framework comes in.

After a bite, people understandably want to know, “How do I teach my dog not to bite?”

But before we teach anything, we need to manage the situation so it doesn't happen again while we're figuring it out.

If your dog bit over a bone, don't give them another bone in the middle of the family room and practice taking it away. If your dog bit a visitor coming through the door, don't invite three more people over this weekend to “work on it.” And if your dog bit a child, don't allow unrestricted access between the dog and child while you're figuring out what happened.

Management isn't avoiding the problem. It's keeping everyone safe while we work on it.

And then I don't really want to teach your dog simply “not to bite.” I want to work on the reason they bit.

Was it fear? Resource guarding? Pain? Handling sensitivity? Frustration? Startle? Did they feel trapped?

If we punish the bite—or the growl that came before it—without changing the reason the dog felt the need to use those behaviors, we haven't necessarily solved anything.

Don't wait for Bite #2

One bite doesn't automatically tell me that you have a dangerous dog. I need to know what happened, how severe it was, what triggered it, whether it's happened before, who lives with the dog and whether we can realistically prevent it from happening again.

But I also don't want to wait for another bite before we take the first one seriously.

Change the environment so the same situation can't happen again. Get your veterinarian involved if pain or a medical problem could be contributing. Find out whether there are any local requirements you need to follow. And get qualified behavior help so you can start figuring out why your dog bit and what needs to change.

You don't need to panic, and you don't need to make every decision about your dog's future today.

But please don't explain the first bite away and wait for the second one.

I'd much rather help you now.
