Content warning: I’m going to talk about human-directed aggression and a dog that exhibits maladaptive behaviors. These are behaviors that are inappropriate for the environment and hinder a dog from coping effectively. Note: Resource guarding itself is not maladaptive. 

What is resource guarding?

Turns out that’s a harder question to answer than I had anticipated. If you’re really interested in the minutiae of terminology around dogs using behavior to control access to resources, this paper will probably do the trick. For our purposes, resource guarding is just what I described, the behavior patterns that dogs use to control access to items of value. 

Dogs are usually much better spotting the body language signals and behavior patterns other dogs use to  maintain access to a resource…but that doesn’t prevent conflicts from happening between dogs. In general, I think that unless there is a big fight or a lot of household conflict between dogs, humans mostly worry about resource guarding when it’s directed at them. 

Not only is the concept of resource guarding more complex than you might think, but dogs use quite a range of behaviors to keep resources in their possession. Some of which are very subtle and require a good eye for canine body language. Here are a few examples of things you might see a dog do near an item of value when another individual gets closer to the item in their possession:

  • Placing their body between an item and the other individual.
  • Leaning over or putting a paw over the item.
  • For food or an edible item, chewing or swallowing at a faster speed or in a larger quantity.
  • Curling the top lip (exposing some teeth) or pulling the lips long (tight) so that teeth are exposed.
  • Growling, often in conjunction with other signals like stiffening.
  • Lunging, growling/barking, snapping.

Resource guarding: start here

If you just need a good overview of what dog trainers typically see, and some advice on how to not make things worse, you can start here:

Creative and judicious use of barriers (like the "drive through window" between our kitchen and living room) have been an important part of helping Petey feel better around resources.

Why resource guarding happens

Have you ever swatted somebody’s hand away because they were trying to take a fry off of your plate? The fries are your resource, and the swatting behavior is what you do to maintain access to your resource (guarding). You have delicious fries, you’re hungry, and you don’t want someone grabbing at your plate to steal your fries! And that’s not a problem. 

Remember at the top of this blog when I said resource guarding itself is not maladaptive (inappropriate for a given environment)?  Most sentient living creatures come equipped with behaviors to prevent others from taking resources from them. Food is an obvious resource. And even though we (allegedly) don’t need fries to survive, in the wild, having and keeping a resource like food is vital to survival. 

If you flew out of your seat and round house kicked the waiter in the throat because they walked past your table while you were eating fries, now that would be a problem. If you did this, it would also make whoever was sitting with you concerned for your [physical/mental/emotional] health, right?

My plan for this blog was to round up some information from our vast catalog of content about resource guarding. But as I sat down to think about my own experiences, I started to think about why it can be such a tricky set of behaviors to deal with. Resources are a really common point of conflict for any species if you think about it. So I think there are a few things to keep in mind when we talk about resource guarding in dogs:

  1. Dogs and humans have very different concepts of ownership. As Emily lays out in Episode #156 of the podcast (linked above), most non-human species operate under finders-keepers rules. We can’t expect them to have a more complex understanding of why we think they should or should not have an item.
  2. The way a dog acts around a resource can vary based on any number of internal and external factors. I am more likely to swat my husband’s hand away from my fries if I haven’t eaten anything all day, or I have a migraine and it’s the only thing that sounds good to me at the moment, or if I had to wait for a long time to get my food and now I’m cranky.
  3. Our dogs are very good at picking up on patterns of behavior to help them predict what comes next. We can use that to our advantage if we’re hoping to create an environment of mutual trust. MaryKaye has a great blog coming out on this topic next week!
  4. Our dogs are very good at picking up on patterns of behavior to help them predict what comes next…which means if there is a long history of having resources taken away, they might think that’s what’s coming next.
  5. Dogs communicate with their bodies. From head to tail, from subtle to obvious, they express their internal state with body language and a limited repertoire of vocalizations, including growling and barking. 
  6. Sometimes our dogs can react or display behaviors that affect us in ways we did not anticipate. For a very long time I would freeze any time Petey would bark at Big Man. It took me many years to understand his body language well enough and for the two of us to build skills around moving away from triggers together.

Here are a few places we discuss the whys of resource guarding and thoughts on next steps: 

What would you do?

Do you really know how you’d react if your dog started displaying behaviors that concerned or even frightened you? If the fuzzy little guy you brought home to be your friend started leaping off the couch to hover and growl over a Benebone that had been lying on the floor for hours just because you stood up, would you know what to do? You might think keeping a spray bottle on hand to deter their behavior and safely take an item away seems like a reasonable idea. Depending on your own learning history, you might think pinning a dog to the ground could teach them a lesson they need to learn.* 

What if I told you this hypothetical situation and subsequent human reactions comes from my actual household? 

Even if it doesn’t look as extreme as the example above, resource guarding has a way of taking you by surprise. A growl over the food bowl. A snap while reaching for a toy you *thought* you were playing with together. Running off with some underoos that didn’t quite make it into the hamper. And our own reactions don’t always come tempered with experience, let alone any kind of plan. A holler to knock it off. A reactionary “HEY!?” A quick session of pry-the-jaws-open. 

Something my dear husband has to remind me of occasionally is that MOST PEOPLE have lived with dogs their whole lives and have never done a lick of what we at Pet Harmony like to call Capital-T training. The kind of training that might require a treat bag, a clicker, and a plan. Most people I know in my regular life have never worked with a dog trainer, let alone a behavior consultant or veterinary behaviorist. Before I got into the field of training and behavior…how was I supposed to be prepared for a dog to lunge and snap at me because I was cleaning up his mess inside of a tent while he was lying several feet away?

All beings in a household are learning from their shared environment and each other all the time, of course. I only had to see Big Man pick onions out of his food a few times before I asked him about his aversion to them. Turns out he thinks the texture is gross, but is fine with the flavor. He didn’t stand in the kitchen and feed me Reese’s Pieces to train me, but I cook pretty often, and after 22 years together, cutting onions into very tiny pieces when I cook them is a behavior that I might need Capital-T training to change. 

Not only is resource guarding a tricky thing for a human to encounter, it can also manifest in many ways. On top of that, [physical/mental/emotional] health issues can exacerbate problematic behaviors, including those related to resource guarding. So how is anyone supposed to know the right thing to do when their dog exhibits behavior that concerns them around resources? And with so much variation in methodologies, is there even a right thing?

We cannot know our pets’ internal experiences. We can’t really even know that with other humans. We often lack the vocabulary, knowledge, or frame of reference to describe every internal experience. When Petey the Wondermutt jumped up off the couch to growl and put his body on top of a Benebone after Big Man stood up, the best label I had for that behavior is resource guarding. And I know that Big Man felt startled and unable to move past Petey in case his next move was to bite. We didn’t know the best way to deal with this behavior. And this wasn’t the only behavior we were concerned about. 

Here are some blogs that outline how behavior pros work through behaviors where there are safety concerns:

So what actually helps?

I don’t know your situation. The best advice for resource guarding is to work with a knowledgeable professional (who utilizes modern, science-based methods that do not involve “corrections,” fear, or intimidation, of course). They should be able to tell you if what you are dealing with requires support from your veterinary team (or if you need to bring in more help).

The following skills are useful for dealing with any concerning behavior:

Petey looking tense with a toy. Pro tip: don't take photos of your pet with valuable items if they have resource guarding tendencies. (When you know better you do better.)

Working on a lick mat in a safe space, a much better option for everyone!!

Don’t forget to take care of you

If I’ve learned anything in my years of caring for a dog with high support needs, it’s that I deserve and require care, too. I can’t be my best for anyone if my own needs are not met. Additionally, MY reaction to Petey having a hard time can really send me into an anxiety spiral if I’m off my game. Working through behavior change or supporting a pet with behavioral challenges is not easy. Here are a few resources to support you:

If your dog has displayed behavior that has you tiptoeing around them, I can empathize with what that does to your nervous system. I know what it’s like to not know what to do next. To try solutions that might make you cringe in the future. We are all on a learning journey! When we’re armed with better information and we know better, we do better. Here’s to what my journey has taught me.
