Resource Guarding in Dogs: Why It Happens and How to Prevent It Using Positive Reinforcement

By Mary van Kriedt, CCTA/CCDT Certified Positive Reinforcement Dog Trainer & Founder of FreeRun Leashes™ Inc.

One of the most misunderstood behaviors I see as a positive reinforcement dog trainer is resource guarding. The moment a dog growls over a food bowl, stiffens when someone reaches for a toy, or runs away with a prized chew, many owners assume their dog is trying to be dominant, stubborn, or in charge.

In reality, resource guarding is usually rooted in something much simpler: fear. More specifically, it is the fear of losing something valuable. Understanding this changes everything because when we address the underlying emotion instead of simply reacting to the behavior, we can help our dogs feel safer and more confident.

The good news is that resource guarding is often preventable, especially when we begin building trust from the day our puppy comes home. Even if your dog is already showing signs of guarding, positive reinforcement can help change how they feel instead of simply suppressing the behavior.

One of the goals of training should never be to teach our dogs that we're bigger or stronger. Our goal is to teach them that they can trust us.

Building Trust From Day One

One of the questions I hear quite often is, "Can resource guarding be prevented?"

While there are never guarantees because genetics and life experiences also play a role, I absolutely believe we can stack the deck in our favor by building trust from the very beginning.

When I brought my Australian Shepherd, Quinn, home at eight weeks old, I immediately started teaching what I jokingly call "share and share alike."

The goal was never to take things away from him. The goal was to teach him that my hands coming near his food, toys, and favorite chews always meant he was safe and that nothing bad was going to happen.

At mealtime, I would place Quinn's food bowl on the floor and sit beside him while he ate. Sometimes I would simply rest my hand near the bowl for a moment before moving it away. After he had taken a few bites, I might calmly pick up the bowl, glance at it, and immediately place it back down so he could continue enjoying his meal.

Nothing scary happened.

Nothing was permanently taken away.

There was never a confrontation.

I repeated these simple exercises throughout his first week home and gradually reduced them as he continued to show he was relaxed and comfortable with my presence.

Just as importantly, I watched Quinn's body language. If I had ever seen him stiffen, stop eating, or show signs of discomfort, I would have immediately backed up and made the exercise easier. Building trust should never come at the expense of your dog's confidence.

Playtime became another opportunity to teach sharing.

We had a basket full of toys, and those toys became something we enjoyed together. Sometimes I held the toy while we played tug. Sometimes I tossed it for him. Sometimes he proudly paraded it around the house before bringing it back to me. The toys were never something I constantly took away. They became something we shared.

Chews became one of my favorite trust-building exercises.

Years ago, I watched one of my young puppies struggle to hold a chew stick between tiny little paws. I remember thinking, "Why don't I just hold it for him?"

What started as helping a puppy enjoy a chew became one of my favorite training techniques.

I would hold one end of the chew while Quinn happily worked on the other. There was never any pressure or conflict. We were simply enjoying it together.

Even today, eight years later, when I hand Quinn a brand-new chew, he'll often trot around proudly with it, drop it in front of me, and wait. I'll pick it up, admire his prized possession, sometimes hold it while he gets started chewing, and then quietly leave him to enjoy the rest in peace.

There has never been a reason for Quinn to worry that I'm going to steal something valuable from him.

Over the years, we've built a long history of trust.

And that's really what preventing resource guarding is all about.

Not teaching your dog that you're in charge.

Teaching your dog that when you approach, good things happen.

What Is Resource Guarding?

Resource guarding is a normal canine behavior in which a dog attempts to protect something they consider valuable.

That resource might be:

• Food
• Bones or chew sticks
• Toys
• Stolen household items
• Their bed
• Their crate
• A favorite person
• A favorite resting place

Some dogs only guard food. Others only guard high-value chews. Some never guard objects at all but become protective of their favorite person.

Every dog is an individual.

Why Do Dogs Resource Guard?

Resource guarding is deeply rooted in survival.

Long before dogs became our companions, protecting valuable resources increased their chances of survival. Those instincts still exist today, even though our dogs no longer need to hunt for their dinner.

Resource guarding can also develop because of:

• Genetics
• Competition with littermates
• Previous experiences where resources were limited
• Shelter or rescue history
• Pain or illness
• Learning that people approaching means something valuable disappears

Many owners accidentally create resource guarding without realizing it.

Imagine your puppy grabs one of your socks. Your first reaction is probably to chase them around the house and take it away.

From your perspective, you're saving your favorite socks.

From your puppy's perspective, something very different just happened.

"Every time my human comes toward me, they take away my treasure."

It doesn't take many repetitions before some dogs begin running away with objects or becoming protective of them.

They're not trying to be difficult.

They're simply learning from experience.

Learn to Read the Early Warning Signs

Most dogs don't suddenly bite without warning. They usually communicate long before things reach that point.

Watch for signs such as:

• Freezing over an object
• Eating faster as someone approaches
• Turning away while holding something valuable
• Becoming stiff
• Showing the whites of their eyes, often called "whale eye"
• Blocking access with their body
• Low growling

One of the most important lessons I teach clients is to appreciate the growl.

A growl is information.

Your dog is telling you they are uncomfortable.

If we punish the growl, we may suppress the warning while leaving the fear untouched.

I'd much rather have a dog that says, "Please don't come any closer," than one who feels they have no choice but to bite.

Management Comes Before Training

Before changing behavior, we need to prevent our dogs from practicing it.

Every successful rehearsal of resource guarding makes the behavior stronger. Management helps everyone stay safe while your dog learns new emotional associations.

Some simple management strategies include:

• Feed multiple dogs separately.
• Give long-lasting chews in a quiet area.
• Pick up toys that create conflict between dogs.
• Teach children never to disturb a dog while they're eating.
• Keep tempting household items out of reach.
• Avoid grabbing valuable items directly from your dog's mouth whenever possible.

Management isn't avoiding the problem. It's creating an environment where learning can happen.

Using Positive Reinforcement to Prevent Resource Guarding

One of the biggest mistakes people make is believing they should constantly take things away to prove they're the boss.

Unfortunately, that often creates the very problem they're trying to prevent.

Instead, we want our dogs to think:

"When my person comes near me, wonderful things happen."

One of my favorite exercises is beautifully simple.

As you walk past your dog while they're enjoying a chew or eating a meal, calmly toss a small piece of chicken, turkey, or another favorite treat into their bowl or beside their chew, then continue walking.

Don't stop.

Don't stare.

Don't reach for the food.

Simply make your approach predict something even better.

After enough repetitions, many dogs begin lifting their heads happily when someone approaches because experience has taught them that people coming closer means bonus treats, not stolen treasures.

That's the emotional change we're looking for.

Teach Your Dog to Trade

Another wonderful exercise is teaching your dog to trade.

Start with a toy your dog enjoys but doesn't absolutely love.

Offer a delicious treat.

When your dog voluntarily drops the toy for the treat, calmly pick up the toy.

After they've finished the treat, give the toy right back.

That final step is incredibly important.

Your dog learns that sharing doesn't mean losing.

As your dog gains confidence, you can gradually work with higher-value objects.

Teach a Reliable "Leave It"

One of my favorite preventative exercises has nothing to do with resource guarding directly. It's teaching a reliable "Leave It."

Dogs that learn they can walk away from something and still earn a wonderful reward become much less likely to grab and guard objects in the first place.

Start with a low-value treat in your closed hand.

The moment your dog stops sniffing, licking, or pawing at your hand, mark the behavior with "Yes!" and reward them with an even better treat from your other hand.

Gradually progress to placing treats on the floor, toys, and eventually everyday distractions.

Teaching "Leave It" isn't about denying your dog something they want.

It's about teaching them that making a good choice often leads to an even bigger payoff.

Reward Relaxation

Sometimes we become so focused on fixing unwanted behaviors that we forget to reward the behaviors we actually want.

If your dog is calmly chewing a bone while remaining relaxed as you move around the room, quietly acknowledge that wonderful choice.

Walk by.

Drop a small treat.

Keep moving.

You're reinforcing calm, relaxed behavior instead of waiting until there's a problem to solve.

Over time, your dog begins learning that people moving nearby is simply another predictor of good things.

Practice Sharing Throughout the Day

Preventing resource guarding isn't just something we practice at mealtime.

Everyday life offers dozens of opportunities to build trust.

If your dog brings you a toy, admire it before tossing it again.

If they pick up a stick on a walk, don't automatically take it away if it's safe.

If they hand you a ball during fetch, celebrate their willingness to share by immediately continuing the game.

The more your dog learns that sharing doesn't mean losing, the less reason they have to guard.

Reinforce Choosing You

One of my favorite games is rewarding my dogs whenever they voluntarily choose to bring something to me.

If Quinn picks up a toy and walks over to show me, I'll praise him, admire it, maybe play for a minute, and often give it right back.

Those little moments build tremendous trust.

Dogs quickly learn that coming to their people with treasures is rewarding rather than risky.

Avoid These Common Mistakes

When trying to prevent or improve resource guarding, avoid:

• Chasing your dog when they pick something up.
• Repeatedly taking food away to "prove who's boss."
• Punishing growling.
• Cornering your dog while they're eating.
• Pulling objects directly from their mouth.
• Allowing children to bother dogs while they're eating or chewing.

Instead, focus on building trust, creating positive associations, and teaching your dog that people approaching predict wonderful things.

One Final Thought

Looking back, I don't think Quinn ever learned that I was the boss.

I think he learned something much more valuable.

He learned that I was safe.

Eight years later, he'll happily bring me a brand-new chew, drop it at my feet, and patiently wait while I admire it before giving it back.

That didn't happen because I won some battle over resources.

It happened because, over thousands of little interactions, we built trust.

If there's one thing I hope you take away from this article, it's that preventing resource guarding isn't about taking things away.

It's about becoming someone your dog never has to worry about.

Resource Guarding Myths

Myth: My Dog Is Trying to Dominate Me

Fact: Resource guarding is generally driven by the fear of losing something valuable, not by a desire to be in charge. Understanding this helps us focus on building trust instead of trying to overpower our dogs.

Myth: I Should Take My Dog's Food Away to Teach Respect

Fact: Repeatedly taking food away can actually create anxiety and increase guarding in some dogs. Instead, teach your dog that your approach predicts something even better, such as a high-value treat.

Myth: Growling Is Bad Behavior

Fact: Growling is communication. It's your dog's way of saying they're uncomfortable. Rather than punishing the growl, work to understand and address the emotion behind it.

Frequently Asked Questions

Should I punish my dog for growling?

No. Growling is valuable communication. It tells you your dog is uncomfortable. Punishing the growl may eliminate the warning while leaving the underlying fear unchanged.

Can resource guarding be prevented?

While there are no guarantees, many puppies can develop healthy sharing habits through positive experiences and thoughtful training from an early age. Building trust consistently gives you the best chance of preventing resource guarding from developing.

Should I take my dog's food bowl away while they're eating?

In most cases, no. Instead, teach your dog that people approaching their food predict something even better, such as a piece of chicken or another high-value treat. The goal is to build trust, not create anxiety.

Can adult dogs learn not to resource guard?

Yes. Many dogs improve significantly with positive reinforcement, careful management, and patience. More severe cases should be addressed with the help of a qualified positive reinforcement trainer or veterinary behaviorist.

Is resource guarding a sign of dominance?

No. Modern behavioral science recognizes resource guarding as a normal survival behavior rooted in emotion, not an attempt to dominate people.

Whether you're bringing home a brand-new puppy or helping an adult dog build confidence, remember that preventing resource guarding isn't about proving who's in charge. It's about creating thousands of positive experiences that teach your dog they never have to worry when you approach.

When our dogs trust that we respect their belongings and that our presence predicts good things, they become more relaxed, more confident, and far more willing to share. In my experience, that's one of the greatest gifts positive reinforcement training can give our dogs.

Happy Training.
