The Trading Protocol for Prevention and Treatment of Resource Guarding in Dogs

Resource Guarding is a perfectly natural behavior for dogs. It can serve a valuable purpose if they are feral, living on their own, and having to find and protect food, sleeping areas, their puppies, and themselves from harm. The dogs we live with and the dogs we rescue have no need to guard their resources, but they don’t always know that. A dog can become dangerous when Resource Guarding goes awry or is taken to a higher level.

Resource Guarding makes sense to dogs

We see this so often with our rescue dogs: sometimes they were raised in sub-standard situations, did not learn the foundation behaviors necessary for dogs to live productively in homes with humans, and sometimes they even lived in a group of dogs with little human supervision and fewer resources than necessary. The result can be that they bring Resource Guarding behaviors that developed for good reason into their new lives. Resource Guarding is a common basis for aggressive behavior in dogs. In their view, they’re just trying to hold onto things they like; but when they bite people in order to do so, it can lead to a very bad ending to what could have been a really nice story.

Preventing Resource Guarding is Best

It’s best to start every dog off right by working to prevent Resource Guarding behaviors before you even see them occur. I like to begin teaching every dog I meet that I am no threat to them, I will always offer them something in trade for anything they have, and that I will not be so rude as to try to snatch things away from them. Check out our blog post, “Basic Training Skills: Start at the Beginning” for more on prevention.

Don’t inadvertently threaten the dog

When you’ve just met a dog, you don’t know him any better than he knows you. You don’t know if he’s ever met a person like yourself: deep-voiced, high-voiced, hat-wearing, high-energy or slow and lumbering; having good or poor dog interaction skills; responsive to the dog’s communications or not; tall or short, fat or thin, dark-skinned or light. Which one are you, and how is the dog responding to your manner?

You don’t even know if a dog has met very many people before at all. You certainly don’t know how anyone he’s met has behaved toward him, or what habits he’s developed in interacting with humans. It’s best to be polite as you get to know him, just as you would be with a human you’ve just met. To a dog, that means allowing him to approach you rather than approaching him first, dropping a slip lead over his head rather than grabbing for his collar, and asking him if he’d like to trade what he has in his mouth for a super-yummy treat.

Why Would a Dog Give Up Something He Likes?

When a dog has something in his mouth, a bone, a toy, a stick, a dead bird, or whatever else he deems valuable enough to hold onto, you must offer something even more valuable to him if you want him to choose to drop that item. That may sometimes mean simply a piece of kibble, especially if it’s offered in the right way.

Some situations call for an especially good-tasting dog treat. In the case of a dead bird with some dogs, you may need a piece of steak to trade. A dead bird can be quite a treasure if you’re a canine! Remember, guarding what they like and want to keep is a natural behavior; we humans have to carefully teach dogs what we want them to do instead, and we have to make it worth their while to do what we want instead of what comes naturally to them.

How to get started

To offer a trade to a dog, simply hold a small piece of food that you’re sure he will like just in front of his nose while he’s holding the item you’d like him to drop. Chances are that he’ll smell the treat and open his mouth to eat it, and guess what? Whatever he had in his mouth will fall out onto the floor!

Focus on your goal

This is the point at which you should be careful to try to hold onto the treat as he nibbles it, or to have a few treats in your hand and roll them into your fingers one at a time, feeding him the whole time you reach for and pick up the dropped item. The goal is to keep the dog relaxed and comfortable, eating the entire time, never feeling threatened or thinking that he needs to defend himself or his precious treasure from you. If you were reading a magazine, you wouldn’t want anyone to snatch it out of your hands, would you? If someone put their hands on something you were holding, you’d be likely to pull it back from them. We don’t want to put any dog in that position, especially a dog we barely know.

Condition carefully

With a new dog, watch him closely as you feed him and reach for the dropped item; this is a time when he might surprise you by snapping as you grab the item. Lure his face over to one side, away from the dropped treasure, while you keep feeding him and pick up the item. You’re distracting him, but you’re also keeping him happily eating rather than worried about what he might be losing. You’re conditioning him – setting him up for the next time he has something in his mouth that you want. Classical conditioning like this is a powerful training principle. Preventing a bad experience for the dog and yourself is much better than allowing it to happen and then trying to fix it.

Perfect practice makes perfect

Practice this behavior many times with a new dog, in order to help him develop a habit of happily releasing anything we ask for. You don’t want to do it over and over and over on his first day in our home, though. Do it once or twice that first day, giving the new dog a chance to enjoy a bone or chewie for a while, safely in his crate. Practice this exercise each day. You can increase the number of times you do it each day, and the number of times you do it during each practice session, as time goes on. You will begin to see your dog release items more readily, you’ll see him begin bringing his treasures closer to you, and ultimately he’ll begin bringing things to you, perhaps dropping them at your feet, looking to you for a treat.

Put the behavior on cue

Add a cue like “Drop it” or “Give” or one I like, “Thank you,” once the dog is happily offering the behavior. Hold your hand under his mouth to catch the item and say the word just as the dog is dropping the item. He’ll start getting really good at it and appear to be having fun with the game of giving you something. Once he’s reliably dropping things in your hand, begin moving your hand upward a bit at a time so he has to reach for it. He’ll be delivering things to your hand up in your lap in no time!

Pay him his treat every time; just ask a tiny bit more of him with each training session. You can train a retrieve for competition or other applications this way; but the most important thing your dog will learn is how great it is to give you things he has. You will be able to easily get your shoe back after you’ve carelessly left it out and the dog has decided it’s a wonderful toy!

Angus was devoted to retrieving newspapers. The behavior was created through positive reinforcement.

“Inspect the toy” game

One of my favorite things to do with the “Trading Protocol” is to catch a moment when my dog has a toy, ask him to give it to me, give him a treat, and pretend to examine the item to see if it’s good enough for him to play with. I’ll even say things about it like, “Only the best for Angus! Let me check it out – is this a good toy?” as I look it over. Then I give it back, saying, “I think it’s good enough. Here you go!”

It’s light-hearted and fun, it teaches a good lesson, and my dog gets a double reinforcement — a treat plus he gets his toy back! This is great preparation for those moments when you need to get something from your dog and you really can’t give it back — those dead bird moments. You probably won’t give back a dead bird, but he doesn’t know that. How about two treats for a dead bird? Seems fair.

Resource guarding can be dangerous

The most important reason to trade dogs treats for other items is to prevent them from developing that behavior we’ve seen all too often: taking an item, lying down with it and threatening anyone who comes near, whether or not the person was planning to take the item away. Always respect a dog’s threat, because he’s not kidding. A growl means, “I feel threatened. I don’t really want to bite you, but I will if I need to. Please change this situation.” A growl is your cue to take the pressure off, to defuse the situation. Take the dog, yourself, someone else, or another dog out of that picture so the threatened dog feels better. It’s also something to take note of: put the “Trading Protocol” into action with this dog.

Train when the dog is relaxed

Don’t try to train when the dog is still “coming down” from a stressful guarding experience; he needs a chance to cool down, maybe even over a couple of days. Prevent the guarding behavior during that time (and always!) Start training when the dog is relaxed and comfortable, secure and not feeling threatened. And don’t start with that same item he was willing to guard so fiercely. Start with something far less valuable. Make sure the dog is in that relaxed frame of mind throughout your training session. You want him to learn to enjoy that relaxed feeling that comes over him while eating those yummy treats and learning not to feel threatened.

It may take some time

Remember that some of the adult dogs you may meet already have a strong habit of feeling threatened in these situations. Don’t feel inadequate if you can’t change that right away. Revel in the joy of seeing dogs improve quickly when your training helps that happen. Know for sure that even when you don’t see immediate improvement, the dog is learning if you’re following a good teaching process. The behavior is improving, even if at a level you can barely see; continue to follow the protocol. Be sure do your part to prevent Resource Guarding behavior from getting worse.

Practice this with puppies when you’re lucky enough to have the opportunity, in order to prevent Resource Guarding from ever developing. (Note that you may see resource guarding behavior even in some puppies; remember it’s a natural behavior. Puppies start learning as soon as they’re born, so they are never really a “blank slate.”)

Other things dogs guard

There are certainly other things that dogs consider resources worth guarding. This list can include couches, beds, rooms, doorways, dog beds, food or water bowls, their own bodies/personal space, and even people. As with all training, preventing the behavior you don’t want while reinforcing the behaviors you do want is the first step to changing any guarding behavior. Practicing good dog interaction skills like always inviting a dog to come to you rather than approaching him will help.

I find that teaching dogs the “Trading Protocol” helps in these areas too, because it expands their repertoire of behavior choices. The more behaviors a dog can depend on to get him good results, the less he will tend to guard. If bringing something to you is a sure way of getting something good, your dog will choose it frequently. The lesson is, “I know you like that thing you have, and I might let you keep it sometimes. But if I can’t let you keep that item, I’ll make sure you get something just as good or better.”

Additional benefits of training

When your behavior is consistent, your dog will begin to respond as soon as he sees you begin the process of trading. The dog is likely to choose to begin dropping the item as soon as he sees you. At this point, you’ll be starting to see the results of the change in the dog’s emotional response. Previously, he would have started the Resource Guarding behavior; now, he’s starting to drop the item. Look for those subtle changes like the dog’s more relaxed body language and starting to spit the item out of his mouth.

Consistency in your own behavior includes offering treats in the same way each time. Doing so will teach your dog that your hand position is a cue that he’ll be getting a treat. Presenting your hand in that position is a “marker” for the dog. It leads to a treat, so it becomes a conditioned reinforcer – it reinforces the dog’s behavior in and of itself, as long as it’s always followed by a treat. Combined with this conditioned hand position, even a piece of kibble can become a pretty good reinforcer. The way you offer the treats is part of your reinforcement process.

Think of how a clicker extends the reinforcement process, letting the dog know he’s about to get a treat. I don’t recommend a clicker for the Trading Protocol because you’re reinforcing a series of behaviors; but your hand position can be a similar stimulus. The reinforcement begins when your hand appears, and continues through the time the dog drops the item, takes, chews, and swallows the treat. I generally offer treats to my own dogs between the tips of my thumb and forefinger. I’ll sometimes present them to a new dog on my flat palm. Just one more hint of the power of behavior science when applied to the details of training.
