Resource Guarding in Dogs: Why It Happens, What to Watch For, and How to Prevent It

Resource guarding is one of the most serious and misunderstood behavior problems dog owners encounter. It can involve food, toys, bones, space, furniture, or even people—and when it escalates, it can be dangerous.

This article explains why resource guarding happens, what warning signs to watch for, and what actually reduces the risk of it developing or worsening.

What Resource Guarding Really Is

Resource guarding is a natural dog behavior. That does not make it acceptable or safe, but it does mean it is not something humans always create. Dogs are born with tendencies already wired in. Some dogs never guard anything. Others show intense guarding behavior early in life. Every dog is an individual. One thing that is true for all dogs is that unless you do something to change it, they just do what comes naturally.

I’ve Never Seen Him Do That Before

Behavior is not fixed. It is always wiggling. Dogs mature, hormones shift, and behaviors that were always possible can also suddenly surface. People have a tendency to think that what they see is what they get, and it’s what they’ll always get. But your dog can exhibit new behaviors anytime.

A couple weeks ago I started getting up at 5:00am to get things done. My husband nearly had me committed because in the decade since he met me, he’s never seen me do that. Behavior isn’t fixed. The only thing you can count on for sure is that things can change. The process of adolescence also can potentially unlock genes as part of the natural maturation process. For instance, dogs don’t typically bark at the door bell when they are three months old. But at seven, eight, ten months old it becomes another story.

Like any other behavior, once guarding happens once, it becomes more likely to happen again, often with increasing intensity.

Reducing the Risk of Resource Guarding

You cannot guarantee a dog will never resource guard. What you can do is dramatically reduce the likelihood of the behavior by building the right relationship from the start.

Structure, boundaries, and meaningful consequences for both wanted and unwanted behaviors (throughout the day, every day) are the strongest protective factors. Of course, most folks don’t do this because it seems unnecessary. After all, their dog doesn’t guard things (yet). That’s why it pays to put naivete to the side and recognize that your dog will change over time. If you choose to give your dog full autonomy and freedom with no boundaries. Or if you choose to shower them with rewards and there is a total absence of punishment in everyday life, you will absolutely manifest the worst version of your dog possible. So you better hope they don’t have any lurking behaviors in there that you just haven’t seen yet.

Why Structure and the Place Command Matter

Reducing unnecessary autonomy helps dogs understand that humans control space and decisions. Crates and place commands teach dogs that instructions are not optional, which lowers the likelihood of guarding. The place command only works if you enforce it. You need to teach your dog the command, and then you need to enforce it with a negative consequence for breaking command.

This garners respect for humans. But enforcing any kind of rules and boundaries is going to put your dog into a totally different state of mind than one that does whatever they like and never has to listen or modify their behavior. Those dogs will treat you more like a dog, yourself, like a sibling. Because that’s how you’re behaving when you think about it.

Food Bowl Myths and Better Feeding Practices

I meet so many people that think it’s helpful to put their hands in their pup’s food bowl when they are eating. Repeatedly putting your hand in a dog’s food bowl provides little benefit and in my opinion may actually increase tension in dogs predisposed to guarding. There is no need to annoy your dog when they are eating.

If you do want to work on counter conditioning with a dog that is not already guarding, try walking up to them and just tossing a high value food into the bowl. This is the only type of exercise I recommend besides the out command, which I will cover shortly. This exercise won’t necessarily prevent guarding, but it may just build enough of an association that someone approaching the food bowl is a good thing, that it may at least create a time buffer where the dog is expecting a treat which could delay an otherwise nearly reflexive behavior.

And in dogs that may only have mild guarding tendencies it may help rewire their default response to being approached. But be warned, without a correction for a displayed guarding behavior, there is nothing truly inhibiting the behavior.

Feeding dogs in their crates creates a low-conflict environment where they can eat in peace. This is my preference, especially if there are children or other dogs in the house. It is the safest and lowest tension way for your dog to eat. They can enjoy their meal. They don’t have to worry, and neither do you. I’m not suggesting you should rely on management, but I always take a two-prong approach to these things. My recommendation is to train and raise the safest dog possible who makes the best decisions possible, but still make it a point not to put your dog in unnecessarily tense or risky situations. That’s responsible dog ownership.

Recognizing Early Warning Signs

Stillness, stiffness, head lowering, staring, or avoidance of eye contact or very direct and steady eye contact can all be indicators of guarding. Dogs rarely snap without warning. The warning signs are often subtle and missed.

Eating quickly is not a sign of guarding. This is normal, and honestly isn’t the huge deal most people make it out to be. Unless your dog is vomiting from eating so fast, who cares? Dogs that quiver and shake won’t necessarily guard either, but I would be inclined to exercise a lot more caution around a dog that exhibits that level of arousal around food since arousal is really the fuel for all behavior.

The Out Command

One thing is for sure, no matter if your dog guards or not, you should never reach to pull resources from their mouth directly, especially food. This is extremely confrontational, rather you realize it or not. You are essentially telling your dog you want to fight for what they have. Some dogs won’t care, or even interpret things that way, but many will.

We never want to fight with the dog. But we do want to always be in control, and you should absolutely be able to take resources away from your dog, even high value ones. I highly recommend teaching your dog the out command. I will link to videos I have on teaching this command. This teaches the dog that you control resources and they need to disengage from them instantly when you ask.

As you can imagine, this cultivates a lot of respect, but it also just gives you a functional and low conflict way to take things away from your dog. No bites! And there are consequences for non-compliance, of course. But even these consequences, while meaningful, are very emotionally neutral. The dog doesn’t take it personally. We aren’t fighting. We are enforcing our fair and consistent rules.

This command is a must for anybody that has a guarding dog. And don’t forget, having standards for behavior in other contexts on a consistent basis is the thing that is most likely to help keep your dog in a headspace where they view you as a fair, firm and consistent leader who has standards and is worthy of respect.

Frequently Asked Questions About Resource Guarding

Can resource guarding be completely prevented?

No. Genetics play a major role, so resource guarding cannot always be prevented, but building a respectful relationship can greatly reduce the risk. And if guarding is displayed it can usually be eliminated through lifestyle changes and the proper application of contingent punishment for the behavior.

Is resource guarding caused by something I did wrong?

Usually not. Owners may nurture behaviors unintentionally, but they do not generally create the behavior as it is at least partly due to a dog’s genetic tendencies.

Should I put my hand in my dog’s food bowl?

This offers little benefit and may actually increase tension because it’s annoying. Feeding in a low-conflict environment (a kennel) is safer. Practicing counter-conditioning by adding high value food to a puppy’s food bowl may potentially have some benefit later.

What should I do if my dog growls over food or toys?

Growling is a warning sign. Seek professional guidance. Add structure and accountability to your dog’s daily life.

Are some dogs more likely to resource guard?

Yes. Genetics strongly influence whether and how intensely a dog may guard resources.

Can resource guarding be trained out?

I never like to think of behaviors as being trained out, rather they are suppressed or inhibited. They are still there, but they are no longer intact. You an attach a contingent consequence to accomplish this. This makes your dog safer and much more likely to make a better choice. Lifestyle changes can also play a role in your dog’s decision making tree. But yes, most dogs can avoid doing a behavior even though they may have done it many times before. It just takes a committed human.
