The Myth of the Stubborn Dog: Why Your Pup Isn’t Defying You
August 14, 2025Resource guarding, the suite of behaviours a dog uses to retain access to valued items such as food, toys or resting places is a common, evolutionarily grounded response. Left unchecked, early possessive behaviours (for example, a puppy repeatedly stealing items and then guarding them) can crystallise into persistent adult guarding that risks welfare and safety for dog and household alike.
What the science says: definitions and risk factors
Resource guarding is defined as avoidance, threatening or aggressive acts used to retain control of food or non-food items when others approach. It is not a single behaviour but a spectrum from subtle lip-licking and freezing, through growling and snapping, to biting. Recognising early, low-intensity cues is critical because these are the building blocks of later, higher-risk behaviour.
Large-scale and clinical investigations identify multiple factors associated with resource guarding: early socialisation and handling, the dog’s learning history around food and objects, previous consequences of human approaches, and environmental management (for example, competition for resources or intermittent enrichment). Breed, sex and early experiences can influence risk but are not destiny, management and training are powerful modulators.
Why “stealing” matters
When a puppy habitually steals items and then experiences success in keeping them (for example, the human chases them and play ensues, or the puppy is allowed to hoard high-value objects), that sequence reinforces both the theft and the retention. If humans respond by forcibly taking items away or by punishing the puppy, this can increase fear or escalation and make future approaches more aversive to the puppy strengthening guarding behaviours. Early handling and learning around approach and removal shape the emotional meaning of a human approaching an item.
Positive Approaches to Prevent and Overcome
- Change the puppy’s emotion about approaching by humans —approaching with better outcomes: treats, trading up and very gradual, non-threatening exposure. Over time, an approaching person becomes a predictor of something good, not a threat to the resource. This is a cornerstone strategy supported by behaviour-analytic and applied studies.
- Teach alternative behaviours and clear cues — train reliable “drop”/“give” and “leave” using positive reinforcement and give when the puppy offers the item voluntarily. Reinforce offers to relinquish by immediately trading up (better treat/toy) so the puppy learns that giving up yields better outcomes than holding.
- Avoid punishment and force — punishing guarding or using force to retrieve items risks increasing fear, redirecting aggression, or suppressing warning signals. Instead focus on changing the predictor cues and consequences rather than aversive control.
- Manage environment to prevent reinforcement of guarding — remove or supervise access to high-value items (raw chews, small soft toys) while teaching the puppy appropriate responses. Management protects people and puppies while training changes the underlying emotion.
Practical, step-by-step protocol for puppies who steal
Immediate management
- Remove tempting, dangerous or highly valuable items from low-supervision areas; supervise play and free-roaming time.
- Use puppy-proofed bins and store shoes, socks and small toys out of reach.
Training exercises (positive, gradual)
- Trade-up game
- Present a low-value item; when puppy takes it, show a higher-value treat and toss it near the puppy. Praise and toss the treat the moment the puppy drops or looks away from the item. Repeat, gradually making the toss contingent on voluntary This teaches the puppy that humans bringing closer or offering alternatives = better outcomes.
- Approach-and-treat
- While puppy chews a toy, drop a small, tasty treat near (not at) the puppy from a slight distance. Progressively reduce distance across sessions as long as the puppy remains relaxed. The aim is: human approach → treat → positive emotion. Do this for very short, frequent sessions.
- Teach “give”/“drop” with reinforcement
- Pair a cue (“give”) with offering a trade-up reward. Shape the behaviour initially by targeting mouth opening or loosening grip, reward small approximations, then require a full drop before reward.
- Handle-and-touch desensitisation
- For puppies who tolerate touch poorly, start by rewarding calm orientation to hands near body and mouth, then gradually touch the item while feeding treats. If the puppy shows any stress, step back to an easier stage progress must be driven by calm behaviour, not time.
Please note: these are simplified explanations if you are experiencing issues you will likely need some more help.
Monitoring and escalation plan
- Record intensity and frequency of guarding signals (freeze, growl, snap). If signals escalate or if the puppy bites, stop training and consult a qualified veterinary or clinical behaviourist for a function-based assessment. Empirical studies show that interventions tailored to the function and intensity of guarding produce better outcomes.
Broader prevention: enrichment, socialisation and routines
- Provide plentiful, predictable food and toy access so puppies do not learn scarcity. Rotate toys to maintain novelty and supervise high-value chews to control reinforcement history.
- Regular gentle handling, including around feeding and resting, reduces unpredictability of human approaches.
- Socialisation with calm conspecifics and structured play reduces anxiety and competition over resources.
Early, Positive Action pays off
Resource guarding emerges from an interaction of biology and experience. The good news is that early, humane interventions, management plus carefully designed counter-conditioning, desensitisation and positive reinforcement training, can change how puppies perceive human approach and possession. Nipping “stealing” in the bud with trade-up games, approach-and-treat routines, and consistent environmental management greatly reduces the likelihood of low-level possessive behaviour escalating into risky adult guarding. For any sign of escalation (snapping or biting), seek a behaviourist experienced in function-based, force-free work.
