It’s a scenario that can catch any pet parent off guard. You walk past your dog while they’re enjoying a chew bone, or you reach out to pick up a dropped tissue they snatched from the trash, and suddenly you hear it: a low, menacing growl. Their body freezes, their eyes stiffen, and they hover tightly over the prize.
It is deeply unsettling when a dog treats you, the provider of all good things, like a thief.
This behaviour is called resource guarding, and it is one of the most instinctual, misunderstood behaviours in the canine world. Let’s unpack why dogs guard, why traditional advice often makes it worse, and how to safely handle it.
What is Resource Guarding?
Resource guarding is the use of distinct behavioural patterns to control and defend access to an item or asset. To a dog, "resources" aren't just limited to food or bones. A dog can guard:
High-value treats and kibble
Toys, tennis balls, or random trash (like socks or tissues)
Favourite resting spots (the couch, your bed, or their crate)
You (guarding a specific human from other family members or pets)
From an evolutionary standpoint, resource guarding is completely normal. In the wild, a wolf or wild dog who willingly gave up their food or shelter wouldn't survive very long. While our domesticated dogs don't need to fight for survival, that ancient genetic programming can still be present.
The Dangerous Mistake: "Dominance" and Retaliation
For decades, traditional dog training gave pet parents terrible advice: "If your dog growls over food, you need to show them who is boss. Pull the bowl away, roll them on their back, or punish them so they know you own the food." Please, do not do this.
Resource guarding is not about dominance; it is rooted in insecurity and fear. Your dog is afraid they are going to lose something they value. If your dog growls to protect a bone, and you physically yell at them or forcefully rip the bone away, you have just proven their worst fear right: Humans truly are terrifying thieves who steal my treasures. The next time you approach, your dog won't stop guarding and instead will just escalate their behaviour to a snap or a bite because a growl didn't work to protect their asset.
The Subtle Signs of Guarding
Dogs almost always give warning signs before they resort to snapping. Recognising these early, lower-intensity signals can save you from a dangerous escalation.
The Freeze: The exact millisecond you approach, your dog stops chewing or moving. They become completely rigid.
Hovering/Crouching: They lower their head or body tightly over the object, trying to shield it from view.
The Side-Eye (Whale Eye): They keep their snout pointed at the object but track your movement with their eyes, showing the whites of their sclera.
Rapid Eating: If you walk past their food bowl and they suddenly start inhaling their kibble at triple speed, they are guarding.
How to Handle Guarding Safely
Managing resource guarding requires shifting your dog's mindset from "Oh no, they're going to take it" to "Awesome, a human is approaching, which means something even better is about to happen!"
1. Implement Strict Management
Safety first. If your dog guards their food bowl, feed them in a separate room behind a closed door or a baby gate. You can also offer their food in multiple bowls, so they understand once one bowl is finished, another is offered to reinforce positive associations with feeding. Ensure no one, especially children, approaches them while they eat until the bowl is finished and the dog has left the bowl.
If they guard toys, pick those toys up and only allow access when you are practicing structured play.
2. Never "Steal" - Always Trade Up
If your dog steals a sock or a piece of trash, never chase them down and pry their jaws open (unless it is life-threateningly toxic). Chasing makes it a game, and prying makes it a fight.
Instead, trade them. Walk to the fridge, grab a piece of cheese or leftover chicken, and toss it a few feet away from the dog. When they drop the sock to eat the chicken, calmly pick up the sock. They learn that giving up an item results in a massive upgrade.
Dog has a sock ➔ You toss high-value cheese ➔ Dog leaves sock to eat cheese ➔ You safely retrieve sock.
3. The "Walk-By" Game (For Food Bowl Guarding)
If your dog is tense around their food bowl, practice building a positive association from a safe distance where they are completely relaxed:
While your dog is eating, walk past them at a safe distance (well outside their "trigger zone").
As you pass, toss a piece of irresistible treat (like hot dog or freeze-dried liver) right next to or into their bowl.
Do not stop, do not bend down, and do not try to pet them. Just keep walking.
Repeat this over several weeks. Eventually, your dog will look up as you approach, not with a tense growl, but with a wagging tail, thinking: "Yes! The human is coming to add awesome snacks to my bowl!"
When to Call a Professional
Resource guarding can escalate quickly if mismanaged. If your dog is actively lunging, snapping, or biting over items, or if there are children in the household, it may be time to call in additional reinforcement.
Look for a certified, positive-reinforcement behaviour consultant (such as a CDBC or an animal behaviourist) who can customise a systematic desensitisation plan. Avoid anyone who suggests shock collars, prong collars, or physical intimidation, as these tools routinely turn fear-based guarding into severe aggression.
With patience, management, and plenty of high value treats, you can teach your pup that cooperation pays off much better than conflict.
Lastly please be mindful that if your dog resource guards in attending our social sessions, this is often a reason of of friction between dogs. If your dog finds sharing food, toys or even you with other dogs, exclusive sessions are best to avoid conflict whilst working on this behaviour!
