What Is Resource Guarding in Dogs?

Resource guarding refers to a dog displaying behavior (growling, snapping, etc.) intended to convince other dogs or humans to stay away from a particular “treasure” or “resource.”  The “resource” can be food, treats, toys, a place such as a bed or favorite chair, or occasionally a person.  Basically, a resource is anything that is considered by the dog to be of high value.

To understand resource guarding you have to understand how dogs evolved.  First of all, dogs have no means of critical or rational thinking, so they don’t understand what or why they are doing it. For example, even though you feed Fido every day, he doesn’t understand that his next meal will be tomorrow – he doesn’t understand tomorrow.  In the wild, it could be days before Fido can “take down” another rabbit, squirrel, etc.; therefore the “rabbit” he is eating now is the most important object in his world.

In other words, resource guarding is normal dog behavior.   The displays of growling and related body language are the dog’s way of saying, “Back off! This is mine, and I don’t intend to give it up.” In most cases, the dogs are simply communicating, and one dog will back down.  If, however, the dogs fight over resources or if a more timid dog feels particularly stressed, you should separate the dogs around desired objects, like food, bones, and toys. The easiest thing to do is to put them in different rooms, so they can each enjoy their prize. Also, remove potentially guardable items when the dogs are together.

That said, resource guarding can be a serious and dangerous problem if a dog threatens to bite his human family when they try to take something away.  Dogs must be willing to give up things they would rather keep, like that plastic bag or turkey bone.  Resource guarding is a major cause of aggression toward humans, particularly toward children.  Children, especially small children, carry around toys and food where the dog can reach them. Children are less likely to understand the importance of respecting the dog’s possessions and are likely to grab for them. Finally, their height means that bites to children often occur on the face or upper body, resulting in more serious injuries.

What Does Resource Guarding Look Like?

Resource guarding can occur over a variety of objects.  Some dogs only guard what they are actually holding (a toy or bone, for example) or when they’re eating.  Other dogs guard toys or treats in their general vicinity, even when they don’t seem all that interested in them.  A few dogs guard space, like the couch or bed. Dogs may guard resources from other dogs, humans, or both.  Resource guarding can also vary in severity, from the dog that will simply move the object away to the dog that snarls, growls, snaps, or bites if approached.  The guarding behavior can sometimes escalate through these levels as a particular dog perceives an increasing threat.  Lower level behaviors (e.g., snarling or growling) are warnings.  Don’t punish your dog for these warnings, or he may stop giving warnings altogether and move directly to more aggressive behaviors, such as biting.

What Can I Do?

Whether you have a puppy, a new dog that doesn’t yet resource guard, or an occasional, but not dangerous, resource guarder, you want your dog to learn not to guard his food and to willingly give up an item.  This is a classic example of an “ounce of prevention is worth more than a pound of cure.”  Practice these exercises frequently before you really need them.

First of all, if you have a dog with resource guarding issues, or a dog you don’t know, maybe you are house sitting, etc. ALWAYS move the dog away from the item and NOT the item away from the dog.

• Approach your dog’s food bowl while he is eating and, without bending down, drop a delicious treat (something like a piece of chicken or beef) into his bowl.  This will teach him that humans approaching his food are not a threat, but rather something good.  You can also hand-feed your dog to set up a strong association with people as providers of good things. This is especially helpful when you first bring a dog into your home.
• Choose a word or phrase like “drop it” or “give” to use as a release cue when you want your dog to give you whatever he has.  Get an empty paper towel roll, a toy, or other items that will interest your dog, without being high value.  You will also need some really yummy treats (diced cheese, hot dogs, whatever your dog loves). While holding onto one end, offer your dog the cardboard roll or other item, moving it around to make it more exciting until he takes it.  Continue to hold onto it, so he can’t grab it and run.  Now, stick a  treat right under your dog’s nose. Your dog will likely spit out the item. When he does that, give him the treat.
• After this is working consistently, add your verbal cue, “drop it” or “give” (in a happy voice), as he sniffs the treat.  After your dog has finished the treat, entice him with the original item again. Once you are confident that the item interests him, add the cue “take it”. Then, use your cue of “drop it” and repeat the trade.  Your dog is learning that when he lets go, he not only gets a treat, he gets back the item he originally gave up.  Note: When not practicing, move the item out of sight, so that your dog doesn’t keep picking it up, in order to get a treat.

When working on these exchanges, make sure you maintain a non-threatening position like sitting or kneeling and angled a little to the side.  Leaning over or walking directly toward a dog is often a trigger for resource guarding.  If your dog becomes still and stiff or raises a lip at any time, don’t continue.

Remember, the key is to trade for an item of greater value.  And the dog gets to decide what’s valuable. Generally, though, that item will be an especially tasty (and if necessary, smelly) treat. Using food also has the advantage of allowing you to practice this exercise a number of times in quick succession.

If there is a specific item that your dog guards (a chew toy or favorite tennis ball), that item is “off-limits” until your dog learns to willingly share his treasures.  Put the item out of sight. When your dog learns to “drop” items of lesser value, then…and only then…will he be allowed to first practice with his “special” item, and then have access to it on a regular basis. The same principle applies to places. If your dog guards the couch, use a baby gate or tether, so that your dog doesn’t have access to the couch. If it’s your bed, your dog should not be allowed in the bedroom.

If your dog seems to guard you when another person approaches, he is probably guarding himself, not you. Your dog doesn’t feel safe, but is comfortable enough in your presence to stand up to the perceived threat. Small dogs, in particular, tend to act out when their person is holding them. Don’t carry your small dog around everywhere; let him explore and gain some confidence. If your dog is reactive around people, stay at a distance where your dog isn’t reacting and give your dog one tasty treat after another (the size of a pea) until the person is gone. This will help your dog develop a positive association with people.

What If My Dog is Already a Serious Resource Guarder?!!!

If your dog aggressively guards resources, especially if he has made you feel unsafe or if you have children in the home, you should consult a highly trained balanced trainer or behaviorist.
