Why Dominance Fails as a Scientific Concept in Dogs

1. Where the Alpha Model Came From

1.1 Captive Wolves

The model rests on one assumption: that wolves live in rigid linear hierarchies maintained by ongoing aggression, and that dogs inherited the same social imperative.

The observations behind it came from unrelated wolves confined together in enclosures — animals that could neither disperse nor form natural family units. Rudolph Schenkel's zoo studies in the 1940s described intense competition for rank among such groups and produced the term that later became "alpha."

1.2 What Wild Wolves Actually Do

L. David Mech, who did more than anyone to popularize the term, subsequently spent years observing wolves in the wild and reached a different conclusion. Mech (1999) describes wild packs as family units: a breeding pair and their offspring from the previous one to three years. The animals labelled "alpha" are simply the parents. Younger wolves do not fight their parents for control; they disperse to find mates and start families of their own, and sustained contests for rank are rare.

Mech has since argued repeatedly that inferring natural wolf behaviour from captive groups of unrelated animals is a methodological error — roughly comparable to inferring family dynamics from people housed together under duress. The hierarchical aggression observed in enclosures is a product of the housing, not a description of wolf society.

1.3 Why the Correction Did Not Travel

The captive findings entered popular culture in the 1970s and 1980s and were amplified through training books and television long before the wild-pack correction was published — and the corrected version is considerably less dramatic. This is a case where the science moved and the popular model did not.

2. Why Dogs Are Not Small Wolves

Even a correct account of wolf social structure would not transfer straightforwardly to dogs. Domestication has altered social organization, ecological niche, and the relationship to humans.

Dogs have been selected over millennia for reduced aggression toward humans, increased sociability, and heightened sensitivity to human communicative signals (which is why they read human gestures as well as they do). They do not depend on coordinated pack hunting. They occupy a niche in which cooperation with humans, not competition for rank within a conspecific group, is the adaptive strategy — a disposition shaped further by early social experience (during the sensitive period).

The practical consequence is that dogs accept human control of resources readily and without coercion. Nothing in the ethology requires an owner to establish rank through force (and breed differences shape this less than commonly assumed).

3. What Dominance Means in Ethology — and What the Popular Model Gets Wrong

3.1 A Property of Relationships

In ethology, dominance is not a personality trait. It is a property of a relationship, defined by priority access to contested resources and identified by the direction of formal status signals — which individual consistently signals submission to which.

It is also context-dependent. A dog that retains a bone against a housemate may defer completely in other situations. Describing a dog as "a dominant dog" mistakes a relationship variable for a trait, which is a category error before it is an empirical one (the general problem of inferring traits from behavior).

3.2 Between Species, the Concept Does Not Apply Cleanly

Dominance describes competition within a social group for the same resources. Dogs and humans do not occupy the same ecological niche and are not structured around contested priority access in the way a dog–dog relationship can be. Applying the term to human–dog relationships is not standard scientific usage.

3.3 What the Popular Model Claims, and Why Each Claim Fails

That dogs continually test humans for rank. There is no evidence for this, and it requires a motivational system nobody has demonstrated.

That non-compliance indicates a rank challenge. Most problem behavior is driven by fear, anxiety, frustration, conflict, high arousal, pain, or straightforward reinforcement history (and pain in particular is regularly misread as attitude).

That physical intimidation is the remedy. Alpha rolls, leash jerks, and scruff shaking are positive punishment; compliance to end them is negative reinforcement. Both raise stress rather than resolving what produced the behavior.

That dogs will not defer without force. They defer readily to predictable, resource-controlling humans without any of it, because cooperation that pays is reinforcing in its own right (through the same reward systems that drive all canine learning).

4. The Live Scientific Debate

4.1 The Published Exchange

This is where popular anti-dominance writing tends to overstate its case, and it is worth getting right.

Bradshaw, Blackwell and Casey (2009) argued that dominance is a poor framework for understanding companion dog behavior and proposed alternatives grounded in learning history and individual relationships. Schilder, Vinke and van der Borg (2014) responded that formal dominance is present in domestic dogs, expressed through context-independent unidirectional status signals, and that the construct remains useful when properly defined. Bradshaw, Blackwell and Casey (2015) then replied, distinguishing the well-established use of dominance in the ethology of wild species from its contested use in dogs as a character trait or motivational description, and concluding that dominance is a property of relationships rather than a trait of individuals.

4.2 What Follows From It

Two things follow. First, the popular alpha model is not what any side of this exchange defends — even the researchers arguing that dominance is a useful construct are describing formal status signalling between cohabiting dogs, not a human–dog power contest. Second, anyone claiming the scientific question is entirely closed is overstating. What is closed is the application to human–dog relationships and the justification of force. What remains open is how much explanatory weight formal dominance carries in dog–dog social life.

5. Why Dominance-Based Training Harms

5.1 The Learning Mechanism

Forcing a dog into submission is aversive by construction. When the dog complies to stop the pressure, that is escape learning. Neither procedure changes the emotional state that produced the original behavior; both add an aversive event to a situation the dog may already have found difficult.

5.2 The Canine Evidence

Herron, Shofer and Reisner (2009) surveyed 140 owners at a veterinary behavior referral service about techniques they had already tried. Confrontational interventions — striking or kicking, growling at the dog, alpha rolls, staring the dog down, physically forcing items from the mouth — each drew an aggressive response from at least a quarter of the dogs on which they were used. The study is retrospective owner recall in a referral population, which limits it, and it remains the most direct data available.

Vieira de Castro et al. (2020) found aversive-trained companion dogs slower to approach ambiguous locations in a judgement bias test, indicating a more negative mood state. Casey et al. (2021) replicated the pattern with a matched-pair design and larger sample. Rooney and Cowan (2011) add a result that is rarely quoted: dogs of owners reporting more punishment performed worse on a novel learning task — the methods do not merely cost welfare, they reduce learning capacity (the full neurological picture of aversive fallout).

5.3 Misdiagnosis

A dog that guards a bowl, growls at visitors, or pulls on lead is not pursuing status. Treating these as rank challenges directs punishment at behaviors that require counterconditioning, desensitization, management, or arousal work instead (and reactive behavior in particular is a state problem, not a status problem) (arousal being the constraint that most often decides whether training is possible at all).

5.4 Suppressed Warnings

A dog punished for growling learns not to growl. The fear remains, and the sequence that made a bite predictable has been removed. Schilder and van der Borg (2004) documented the underlying process in shock-trained guard dogs, who continued to show stress-related behavior in sessions where no shock occurred, having learned that the handler predicted it.

Where control is not merely absent but consistently unavailable, the relevant framework is the revised account of learned helplessness: passivity is the default response to prolonged uncontrollable adversity, and what gets learned is the presence of control (Maier & Seligman, 2016) (which is why a compliant dog is not necessarily a settled one).

6. Hierarchy in Multi-Dog Households

6.1 What Has Actually Been Measured

Between dogs, hierarchy is real and measurable. Van der Borg et al. (2015) analysed seven postures and twenty-four behaviours in a group of domestic dogs and identified which qualified as formal status indicators: high posture across most dyads, muzzle bite exclusively from the highest-ranking animals, and body tail wag plus low postures as the clearest submission signals.

Vékony and Pongrácz (2024) took this further, testing whether questionnaire-based rank scores predict actual behavior. They did: rank predicted which dog grabbed and kept a toy in a possession test. But the components separated — agonistic and leadership subscores mapped differently onto greeting behavior, which is what one would expect if "dominance" in dogs is several things rather than one. Vékony, Bakos and Pongrácz (2024) found rank-related differences in responses to frustration that likewise do not reduce to a dominant–subordinate binary (frustration having its own distinct mechanisms).

6.2 What It Means for Owners

The practical implications are the opposite of what the popular model prescribes. Stable hierarchies are maintained by subtle signalling, not fighting; conflict in multi-dog homes usually reflects resource competition, pain, poor management, or arousal rather than rank instability. The owner's job is not to install an alpha but to know each dog's resource priorities and arrange the environment so competition does not arise.

7. What Works Instead

Control resources without confrontation. Teach an exchange cue and pay well for it rather than taking things away to make a point. Teach a mat behavior rather than banning furniture by force.

Provide predictability. Consistent routines and contingencies lower baseline stress, and unpredictability is what the stress literature identifies as most costly.

Teach with reinforcement, including clear boundaries. Reward-based training is not the absence of structure. Negative punishment — withdrawing attention for jumping — remains available; what the evidence argues against is adding aversives (with the usual caveats about how withdrawn reinforcement behaves).

Address the actual driver. A dog growling at a stranger needs distance and a counterconditioning plan, not a correction (because behavior does not report the internal state directly).

Build the relationship deliberately. Secure attachment to the handler is associated with better stress regulation (attachment styles in dogs in detail), and handler state itself affects the dog (through mechanisms including emotional contagion).

Refer serious cases. Resource guarding, aggression, and severe fear warrant a veterinary behaviorist. Professional bodies including the American Veterinary Society of Animal Behavior have issued position statements favouring reward-based methods and advising against dominance-based approaches.

8. Summary: Three Claims at a Glance

The alpha wolf model — Origin: unrelated wolves confined together in enclosures. Status: a captivity artefact. Wild packs are families led by breeding parents, with dispersal rather than rank contests (Mech, 1999). Relevance to dogs: minimal, and doubly so given domestication.

Formal dominance between dogs — Status: real, measurable, and actively debated. Formal status signals have been identified quantitatively (van der Borg et al., 2015) and rank scores predict competitive behavior (Vékony & Pongrácz, 2024), while researchers continue to disagree about how much the construct explains. Relevance: describes dog–dog relationships, not dog–human ones.

Human–dog dominance — Status: not standard scientific usage and unsupported. Dogs defer to resource-controlling humans without coercion. Derived methods provoke aggression in a substantial minority (Herron et al., 2009), worsen mood (Vieira de Castro et al., 2020; Casey et al., 2021), and reduce learning ability (Rooney & Cowan, 2011).

What most problem behavior actually is — Fear, anxiety, frustration, conflict, arousal beyond the individual threshold, pain, or reinforcement history. Each has an indicated intervention, and none of them is a rank correction.

9. Research Gaps and Critical Appraisal

The dominance debate in dogs is not closed. Schilder et al. (2014) argue formal dominance is present and useful; Bradshaw et al. (2009, 2015) argue it is a relationship property routinely misapplied as a trait. Presenting this as settled overstates the position.

Rank assessment is largely questionnaire-based. Vékony and Pongrácz (2024) note there is no fully validated hierarchy questionnaire for cohabiting companion dogs, and that behavioural validation of survey-derived ranks has been rare — their study is a step toward closing that gap rather than the last word.

The training-methods evidence is correlational. Vieira de Castro et al. (2020) and Casey et al. (2021) establish association; owners choosing aversive methods may differ systematically, and dogs' full histories are rarely known.

Herron et al. (2009) is retrospective and selected. Owner recall in a referral population already presenting with behavior problems is the most direct evidence available and not a controlled trial.

Wolf-to-dog inference remains weak in both directions. Correcting the captive-wolf error does not license the reverse move of using wild-wolf family structure as a model for dog–human households.

Individual variation dominates. Temperament, history, and arousal baseline shape social behavior more reliably than any group-level rank description (as the temperament literature describes).

10. Conclusion

The popular dominance model is a historical artefact kept alive by media and tradition rather than by evidence. It began with unrelated wolves in enclosures, was corrected by the same researcher who popularized it, and was carried across to dogs without accounting for domestication, learning history, or the difference between within-species and between-species relationships. What survives scrutiny is narrower and more interesting than either camp's slogan: formal dominance is a genuine feature of dog–dog relationships and remains under active scientific discussion, while the claim that humans must occupy an alpha role is neither standard usage nor supported, and the methods built on it provoke aggression, worsen mood, and measurably impair learning. The model persists because it offers a simple answer and a feeling of control. The cost is a dog that has been taught to stop signalling without being helped with what it was signalling about. The useful question was never who is in charge. It is what this dog is actually experiencing, and whether it can learn without being afraid.

Key Insights (Takeaways)

• The alpha model describes captivity, not wolves. Wild packs are family units in which the breeding parents lead and offspring disperse rather than compete for rank (Mech, 1999) — and the researcher who popularized the term spent decades correcting it.

• Dogs are not small wolves. Domestication shifted the adaptive strategy toward cooperation with humans, and dogs defer to resource-controlling humans readily without any need for physical enforcement.

• Dominance is a property of relationships, not a trait of individuals. It is defined by priority access and the direction of formal status signals, it is context-dependent, and applying it between species is not standard scientific usage.

• Between dogs, hierarchy is real — and still debated. Formal status indicators have been identified quantitatively (van der Borg et al., 2015) and rank predicts competitive behavior (Vékony & Pongrácz, 2024), while researchers continue to disagree about how much the construct explains (Schilder et al., 2014; Bradshaw et al., 2015).

• Dominance-based methods carry measurable costs. Confrontational techniques drew aggressive responses from at least a quarter of dogs on which they were used (Herron et al., 2009), aversive-trained dogs show a more pessimistic judgement bias (Vieira de Castro et al., 2020; Casey et al., 2021), and punishment-exposed dogs performed worse on a novel learning task (Rooney & Cowan, 2011).
