Dominance Theory: Why Singapore Owners Can Skip Alpha Rolls
The Animal and Veterinary Service and mainstream ethologists such as Bradshaw conclude that dominance theory, as commonly applied to owners, is an outdated explanation for most dog behaviour. Aggression is usually rooted in fear or context, not a bid for rank. Below, we summarise the evidence, show how it applies to everyday training, and explain what you can do instead.
TL;DR:
A growl over a chew or a stranger leaning close signals a specific trigger; record what happened before, the dog’s body language, and the outcome.
The AVS advisory issued in July 2025 urges owners to avoid shock and prong collars, allowing them only as a last resort under professional supervision.
Start counterconditioning where your dog can eat and think; pair the trigger with rewards, then move closer only while the dog stays relaxed.
Seek professional help for worsening incidents, bites without warning, sudden temperament changes, or fear that prevents eating or settling; behavior change takes weeks to months.

What does dominance theory claim about alpha dogs and pack leaders?
Dominance theory says that dogs are constantly trying to climb a social ladder, and that you must be the “alpha” to keep your dog in line. In plain terms, it presents your household as a wolf pack, with you as the pack leader and your dog as a challenger waiting for a moment of weakness. Under this model, almost any unwanted behaviour, from pulling on the lead to jumping up or growling, gets read as a power grab.
Trainers who follow this model have typically relied on a familiar set of techniques:
Physical corrections, such as pinning a dog down, scruff shakes or leash jerks.
“Alpha rolls”, where a dog is forced onto its back and held there.
Aversive collars, including prong and electronic shock collars, used to “correct” a dog the moment it misbehaves.
Rules about status, such as eating before the dog, going through doors first or never letting the dog on the sofa.
We mention these so you can recognise them, not because we recommend them. The biggest misunderstanding is that dominance is a personality trait, as if one dog is simply born “dominant” and another “submissive”. The research does not support that picture. A dog that pulls, guards a toy or growls at a visitor is usually responding to a specific situation, not pursuing a lifelong ambition to lead your household.
What does modern science say about dominance in domestic dogs?
The scientific consensus is that dominance describes the outcome of a particular interaction between two animals, not a fixed trait of an individual. Ethologists and veterinary behaviourists report that canine social structures are complex and not built on linear hierarchies, and that dominance is not a character trait of individual dogs. Research by Bradshaw and colleagues points the same way. Dogs also do not treat human families as wolf-style pack hierarchies.
A dog does not view your household as a linear dominance hierarchy, so there is no rank for you to “win”. (UC Davis School of Veterinary Medicine) That finding changes what we ask of owners: meet the dog’s needs and teach clear skills, rather than assert status.
Experts outside the clinic say much the same. Researchers such as Dr Clive Wynne note that dominance belongs to specific interactions, and that the human “alpha” framing is unnecessary when owners meet their dogs’ needs. Formal position statements have also been issued by professional bodies, including a position statement on the use of dominance theory that cautions against using it to justify punitive training.
How did researchers reach these conclusions? Mostly through careful behavioural observation of how dogs actually interact, and through clinical assessment of dogs referred for problem behaviour. When behaviourists look at who growls, who backs away and what happens just before an incident, they keep finding specific triggers such as fear, pain, frustration or a valued resource. They do not find a steady, household-wide struggle for rank.
For training, the message is practical. If dominance is not the cause, then dominating the dog is not the cure. Teaching your dog what to do, rewarding it and changing how it feels about difficult situations all tackle the actual cause. A “show them who is boss” approach tackles a cause that is not there.
Why does the alpha dog myth persist?
If the evidence is this clear, why do so many people still believe in the alpha dog? Several forces keep the idea alive:
It is a simple story. One tidy explanation for every behaviour is more appealing than the truth, which is that different dogs act for different reasons in different moments.
Aversive methods seem to work. A harsh correction can stop a behaviour on the spot. That visible, short-term suppression convinces owners the method is sound, even though the underlying fear or frustration remains.
Its roots are in early wolf studies. Observations of unrelated, captive wolves were widely repeated and later applied to pet dogs and their families.
Confident, high-profile trainers have endorsed it. When a famous trainer presents dominance as fact, many owners understandably trust it.
Notice that the belief survives not because the data are strong, but because the story is easy to retell and the quick fix feels like proof. It is worth being honest about this with yourself. If a technique ever “worked” for you, it may simply have silenced a dog that was still worried underneath.
What do dominance-like behaviours actually look like?
Between dogs, what people call dominance is usually ritualised signalling. Dogs use posture, stiffening, a hard stare, a raised lip or a turned head to say “I would like some space” or “that is mine”. In most cases, one dog yields, the tension drops and nothing further happens. These are conflict-resolution tools, and they work precisely because they allow dogs to settle things without fighting.
With people, the picture is similar. What looks like a dog “controlling” you is typically control of a resource in that moment, such as food, a toy or a sleeping spot, and not a constant wish to lead. A dog can guard a bone and be perfectly relaxed about everything else.
Owners commonly misread dogs in ways like these:
Mistaking fear for dominance. A dog that growls when a stranger leans over it is often frightened and trying to increase distance.
Mistaking excitement for defiance. A dog that jumps up, pulls ahead or ignores you at the park is usually overstimulated, not plotting to outrank you.
Missing body language. Lip licking, yawning, turning away and a tucked tail are polite requests for space that are easy to overlook.
Punishing the warning. Scolding a growl teaches a dog to hide its early signals, which is one of the riskiest outcomes in training.
Treating a single incident as a personality. One tense moment over a chew does not make a dog “dominant” for life.
Learning to read these signals gives you a far more accurate picture than any rank label ever could.
What causes aggression, and how do behaviourists assess it?
Aggression is a symptom, not an identity. Clinical literature describes it as a sequence, from warning through a pause to action, and stresses that context, sequence and health status are essential for telling normal from pathological aggression and for judging how dangerous a dog is. Veterinarians likewise emphasise that aggression has specific triggers, most commonly fear, and that treatment focuses on identifying triggers, managing the environment and counter-conditioning rather than punishment.
Common causes include:
Fear or anxiety, the most frequent driver behind growling, snapping and lunging.
Pain or medical problems, such as ear infections, arthritis or other conditions that make a dog less tolerant of touch.
Resource guarding, where a dog protects food, toys, a resting place or a person.
Redirected arousal, when a dog cannot reach what upset it and turns on whatever is nearby.
Predatory triggers, where fast movement sets off chasing and grabbing.
The warning sequence matters enormously. A dog that stiffens, growls and snaps in clear stages is communicating, and you have time to respond. A dog that has learned to skip the warning steps becomes unpredictable, because the signals that once gave you notice have gone quiet.
When a vet or behaviourist assesses risk, they weigh the context in which incidents occur, how often they happen and how severe the bites or attempts have been. They also check for underlying medical causes, since treating pain can change behaviour dramatically.
Pro Tip: Keep a simple log of every incident: where it happened, what came just before, what the dog’s body looked like and how it ended. Patterns in the log can help reveal the real trigger.
If you would like a closer look at managing the distance at which your dog stays calm, our guide on aggressive dog threshold management walks through it step by step.
Why are aversive and dominance-based training methods risky?
Aversive tools such as shock collars and prong collars work by causing discomfort or fear, so a dog learns to stop a behaviour to avoid it. The problem is that they can also silence the warning signals a dog gives before it escalates. Animal-welfare professionals in Singapore report that aversive training may suppress warning behaviours such as growling and lunging, potentially creating a more dangerous situation where a dog bites without warning.
In July 2025, the Animal and Veterinary Service issued an advisory urging pet owners to avoid these tools and to favour humane, science-based, positive-reinforcement training. Developed by a workgroup that included veterinarians and animal welfare groups, the advisory runs to 34 pages and recommends aversive tools only as a last resort and under professional supervision. You can read the full AVS advisory on aversive dog training devices on the official site.
The AVS advisory tells owners to avoid aversive tools such as electronic shock collars and prong collars, and to treat them as a last resort under professional supervision only.
Local reporting echoes the concern. The Straits Times covered how shock and prong collars can cause pain and fear and worsen problems, while earlier coverage described a public workgroup reviewing dog training standards and the use of aversive devices.
Dominance-style force can leave longer-lasting negative emotional effects than reward-based training. That is the direction of the research summarised by Psychology Today, which notes that force-based methods set out to push dogs into subordinate roles. A dog trained this way may look obedient while quietly feeling anxious, which is a poor trade for you and for the dog.

What works instead of dominance training?
Start by separating two ideas. Obedience training teaches a dog skills, such as sit, recall and loose-lead walking. Behaviour modification changes how a dog feels about something, such as strangers, other dogs or being left alone. Many problems that owners call “dominance” are really emotional, so they need the second kind of work. AVS guidance explains that dogs learn by association and consequences, and that positive reinforcement and behaviour modification address the underlying emotional state, not only obedience.
Here are practical steps you can start at home:
Reward what you like. Mark and reward calm, polite choices, such as looking at you or sitting, so your dog learns what pays off.
Find the threshold. Work out the distance at which your dog notices a trigger but can still eat a treat and think.
Counter-condition. Pair the trigger at that safe distance with something your dog loves, so the trigger starts to predict good things.
Desensitise gradually. Reduce the distance in tiny steps, only when your dog stays relaxed.
Manage the environment. Use gates, leads and distance so your dog is not repeatedly pushed past its limit while it learns.
Stay consistent. Everyone in the household should follow the same plan.
Pro Tip: End every session while your dog is still keen and relaxed. Short, successful sessions build confidence faster than long ones that finish in a struggle.
If your dog is fearful, our behaviour modification plan for fearful dogs lays out the stages in detail. When you start working on introductions and enrichment, practical guides such as this one on preventing dog and cat fights can help you set up safe, calm first meetings. If bites, escalating incidents or fear that does not ease are part of the picture, move on to professional help.
When should you seek professional help?
Some situations call for a vet or a certified behaviourist. Do not wait if you notice any of the following:
Incidents that are becoming more frequent or more severe.
Bites, or near misses, that came with little or no warning.
A change in your dog’s usual warning sequence, such as skipping the growl.
Aggression toward children, other household members or guests that you cannot safely manage.
A sudden change in temperament, which may signal pain or illness.
Fear so strong that your dog cannot eat, settle or recover after a trigger.
A good behaviour consult usually has a clear shape. It begins with a medical check, since pain and illness can drive behaviour. The behaviourist then takes a detailed history, maps your dog’s triggers and builds a tailored behaviour modification plan for your household. Expect homework between sessions, because most of the change happens in daily life.
Be realistic about timing. Behaviour change takes weeks to months, not days, and progress is rarely a straight line. Our plan for reducing aggression towards owners shows how to approach the process. Our guide to dog aggression management techniques is also a useful companion while you wait for your appointment.
A practical, humane view from Mark
As an AVS-accredited trainer, I have watched the “who is the boss?” question lead owners in the wrong direction again and again. The most lasting improvements I have seen came from asking a different question: what is this dog feeling, and what would help it feel safer? A fearful dog that once lunged at every passer-by can learn, through patient rewards and gradual exposure, to walk past with a loose lead and a relaxed face. That change holds because the dog’s feelings changed, not because it was frightened into silence.
Be patient with yourself and your dog. Progress takes time, and having support beyond the last session makes a real difference, which is why we offer free lifetime support to every client.

FAQ
How do dogs decide who is dominant?
Dogs do not hold a fixed rank in the way old theories suggested. Dominance is an outcome of a particular interaction, such as who gets a bone or a spot on the sofa, and it can change from one situation to the next. Researchers describe it as a property of interactions, not a personality trait.
What are some signs of dominance behaviour in dogs?
What people call dominance is usually resource guarding, fear or overexcitement. Typical signs include stiffening, a hard stare, growling over food or toys, or pushing past you at doors. These point to a specific trigger in that moment, so look at the context before assuming your dog is trying to take charge.
How can you tell if a dog is being dominant?
Check the situation and the dog’s whole body, not just one behaviour. A dog that growls over a chew and relaxes once the chew is gone is guarding a resource, while a dog that growls when approached by strangers is probably frightened. Keeping a log of triggers helps you and a behaviourist see the real pattern.
Are girl or boy dogs better behaved?
Sex alone does not decide how well behaved a dog is. Early socialisation, health, training, and each dog’s temperament matter far more. Choose a dog for its individual personality and plan to train it with rewards, whichever sex it is.
