How to Stop Resource Guarding in Dogs
Short answer: To stop resource guarding in dogs, start with safety: feed your dog alone, pick up prized items, and never punish a growl or take things by force. Then teach your dog that an approaching person brings something better, using trades and tossed treats from a relaxed distance.
Any bite, children in the home, or guarding that starts suddenly means a vet visit first, then a qualified behavior professional.
This guide covers the warning signs, the safety rules, a step-by-step trade-up plan, and who to call for help. It also explains where our force-free Manners and Obedience Levels in Crystal Lake fit, and where they don't.
What Is Resource Guarding in Dogs?
Resource guarding is when a dog uses avoidance, threats or aggression to keep control of food or other items while a person or animal is near. That is the definition recommended in a 2018 study of expert opinion on resource guarding.
Guarding is not spite. The ASPCA says guarding possessions is normal behavior for dogs. Dogs guard food, chews, toys, stolen socks, beds, sofas and even a favorite person, and the same plan works for all of them.
Resource guarding is common. In a study of 1,016 dogs at a New York SPCA shelter, 15% guarded resources, mostly at a mild to moderate level (McGuire, 2019).
Pet dogs guard too: a 2001 survey of Eastern Canadian veterinary clients found aggressive guarding toward people in 20% of companion dogs, as cited in a 2026 Animal Welfare paper.
A newly adopted dog may need extra room around food while it settles. Our guide to settling a newly adopted rescue dog covers those first weeks.
Warning Signs of Resource Guarding, From Mild to Severe
Resource guarding signs climb a ladder, from quiet signals that are easy to miss up to a bite. The Santa Fe Humane Society sorts them into mild, moderate and severe guarding behaviors, and the AKC adds the hard stare and "whale eye", when the whites of the eyes show.
Level | What you may see | What to do |
Mild | Hovering or hiding items, freezing when approached, eating faster, carrying the item away | Manage the home now and start trade-up games at a distance |
Moderate | Hard stare or whale eye, lip lift, growling or snarling, snapping | Stop approaching the dog with the item; book a vet check, then a behavior professional |
Severe | Lunging or biting | Vet first, then a veterinary behaviorist or certified behavior consultant; adults only near the dog |

A growl is information, not bad manners. The PDSA explains that punishing a growl is more likely to "train" that warning step out of a dog, so the next warning may be a snap.
Reading the early rungs is a family skill. It is the heart of our Canine Communication seminar on how dogs speak, which is built to keep dogs and families safe.
Safety Rules to Follow Before Any Training
Safety comes before any exercise. These rules apply to every guarding dog, whether the signs are mild or severe.
Never punish a growl. The Santa Fe Humane Society warns that a dog punished for growling will learn to bite without warning.
Never take things by force. Don't grab, chase or corner your dog to get an item back. Dogs Trust advises against chasing or cornering; trade instead.
Adults only. Children never run these exercises, and never feed, approach or take things from a guarding dog.
Children need the firmest line. The ASPCA calls a home with children and a resource-guarding dog "unacceptably risky" and says not to try the food exercises with anyone under 18. Best Friends Animal Society adds that a child should never be responsible for feeding a dog who guards food.
Use baby gates at every meal and chew time. Our guide to safe roles for kids in family training shows how children can still be part of the dog's life.
Why Dogs Guard, and When to See a Vet First
Dogs guard because keeping valuable things is an instinct, and a dog repeats whatever works. Health matters too: Dogs Trust notes strong links between resource guarding and a dog being in pain or feeling unwell.
See your veterinarian before training if guarding starts suddenly or appears in an adult dog that never guarded before. The AKC advises a vet visit for adult-onset guarding, because a change in behavior may point to a medical issue.
Punishment backfires. The AVSAB lists increased anxiety and fear-related aggression among the effects of aversive methods, and the 2018 expert study notes confrontational techniques can make aggression worse. We never use prong, choke or shock collars.
Step 1: Manage the Home So Guarding Can't Happen
Management means arranging your home so your dog never needs to guard. It stops the habit growing while you train.
Feed meals in a crate, a pen or a separate room with the door closed.
Let your dog leave the area before you pick up the empty bowl.
Give long-lasting chews only in the crate or behind a gate.
Separate all pets before meals and treats.
Pick up toys after play and keep socks and kids' toys out of reach.
Block the sofa or bed if your dog guards resting spots.
Keep a short log of each incident: the date, the item, who approached, and how close they got before your dog tensed.
Step 2: Teach Your Dog to Trade Up
The trade-up teaches your dog that letting go of an item earns something better. Best Friends recommends practicing many levels of trades, and Dogs Trust suggests throwing the exchange item past your dog.
Show a better treat. Start with a low-value item, like a plain toy, and a much better treat.
Toss it past your dog. Throw the treat a few feet beyond your dog, so it walks away from the item.
Pick up the item. Calmly pick it up only once your dog has moved away and is busy eating.
Give it back if safe. Return the item when it is safe, so trades don't always end the fun.

Practice with items your dog does not guard yet. If your dog stiffens or stares, go back to a lower-value item.
If your dog grabs something dangerous, don't reach for it. Dogs Trust suggests calling your dog away or creating a distraction, such as scattering treats on the floor. It helps to build a dependable come-when-called cue before you need it.
Step 3: Change How Your Dog Feels When People Approach
This step, called desensitization and counter-conditioning, aims for a dog who is happy, not tense, when someone walks toward its food. Only adults do it, and with moderate or severe guarding, only with a professional guiding you.
Stand 6 to 8 feet away while your dog eats, toss a piece of chicken toward the bowl, as the AKC describes, and walk away.
Over many meals, toss from a little closer while your dog keeps eating loosely.
Walk up, drop a treat into the bowl, and leave.
Later, offer a treat from your hand near the bowl; the ASPCA plan then adds touching and lifting the bowl.
Each other adult in the home repeats the steps.
Move on only when your dog is clearly relaxed. The ASPCA rule is to repeat each stage until your dog eats in a relaxed way for 10 meals in a row. If your dog stiffens, eats faster or stares, go back a stage.
Helpful Cues: Drop It, Leave It and Go to Your Place
Everyday cues let you get things back without a struggle. "Drop it" means let go for a reward, "leave it" means don't take that, and "go to your place" sends your dog to a mat. All three are taught with rewards, never by prying a mouth open.
Our Levels classes cover household manners and formal obedience cues, and our eight-week Masterclass with weekly three-hour visits adds structured repetition. If your dog has mild signs, no bites and no children at risk, call us first so a trainer can talk through fit.
Our classes build foundation skills; they are not a treatment program for resource guarding or aggression.
Resource Guarding in Puppies
Puppies can guard too, and puppyhood is the easiest time to prevent it. Dogs Trust calls puppyhood the best time to teach a dog it doesn't need to worry about losing things it values.
Drop a tasty extra into the bowl as you walk past, then leave.
Play short trade games with toys every day.
Don't take the bowl away to "test" your puppy. The 2026 Animal Welfare paper lists removing food at mealtime among factors linked with guarding.
Give chews in a crate or pen so other dogs can't compete.
Our puppy socialization checklist by age covers what else to introduce and when.
Who to Call: Trainer, Behavior Consultant or Veterinary Behaviorist
The right professional depends on how serious the guarding is and who lives with the dog. When in doubt, start with your vet.
Your situation | Who to call first | What they do |
Mild signs only, no growling at people, adults only at home | A force-free trainer | Coaches management and foundation cues such as trade, drop it and leave it |
Growling, snarling or snapping at people, or guarding getting worse | Your vet, then a certified behavior consultant | Rules out pain, then builds a behavior plan for your home |
Any bite, children in the home, or sudden onset | Your vet, then a veterinary behaviorist (DACVB) or certified applied animal behaviorist (CAAB) | Medical and behavior diagnosis, a treatment plan, and medication if needed |
Credentials matter. The ASPCA recommends a CAAB or a board-certified veterinary behaviorist, and notes that aggression expertise is not required for CPDT trainer certification, so ask any trainer about guarding experience.
Ask how a trainer would handle a growl. If the answer involves corrections, a prong, choke or shock collar, or "being the alpha", keep looking. Our list of questions to ask before hiring a dog trainer helps you compare.
Frequently Asked Questions
Can resource guarding be cured?
Resource guarding can often be greatly reduced. An ASPCA research team describes food guarding as often responsive to treatment and readily managed in a home. Expect to keep some management, such as feeding your dog apart, even when training goes well.
Will my puppy grow out of resource guarding?
No. Dogs Trust says resource guarding isn't a behavior dogs grow out of, so start early with managed meals, bowl drops and daily trade games. If your puppy growls, snaps or guards more over time, talk to your vet and a behavior professional.
Why did my dog suddenly start resource guarding?
Sudden guarding often has a cause, so see your vet first: pain and illness are linked with guarding, and the AKC advises a vet check for adult-onset cases. Also note recent changes, such as a new pet, a new baby or a move.
Should I take my dog's food away to show who's boss?
No. Taking food away to dominate a dog can make guarding worse, according to the ASPCA, and the Santa Fe Humane Society calls the "show who's boss" approach a myth that will likely provoke a bite. Trade up instead, so your dog learns that people near the bowl bring good things.
How long does it take to stop resource guarding?
No reliable source gives a fixed timeline. It depends on how severe the guarding is, how long it has gone on, and how consistently everyone manages. Measure progress, not weeks: the ASPCA moves on only after 10 relaxed meals in a row, and you go back a step if your dog tenses.
Your Next Step
Decide where your dog sits on the ladder today. If you have seen any bite, guarding around children or a sudden change, call your veterinarian this week and ask for a referral to a behavior professional.
