500 Years of Dog Training

A selective history of how care, control, science, war, work, and popular culture have shaped what we now call “dog training”

The short version

People have been living and working with dogs for far longer than 500 years. I am using this window because it lets us trace several forces that still shape training today: colonial expansion, the growth of police and military dog programs, the rise of behavior science, the spread of correction-heavy pet training, and the modern focus on welfare and emotional health.

There was never one single “old way” to train dogs. Care, reward, coercion, partnership, and violence have coexisted for centuries.
Methods do not develop outside culture. Ideas about obedience, hierarchy, labor, race, disability, family, and state power have all influenced what people ask dogs to do and how they teach them.
Behavior science gave us powerful tools for understanding learning. It did not make every use of those tools humane.
Modern welfare research asks a bigger question than whether a method can suppress behavior. It asks what the dog experiences, what the dog learns, and what happens to trust and emotional health.
History helps us recognize the choices hidden inside traditions that are often presented as natural or inevitable.

Scope note: This is a broad, guided history, not a claim to cover every culture, training tradition, working role, or Indigenous relationship with dogs.

Start with the videos

I have approached this history in a couple of different ways on YouTube. The shorter video connects colonialism, slave-catching, police and military dog programs, and modern training culture. The longer video follows five turning points that changed how people teach dogs.

Watch 5 Moments That Changed Dog Training

Before 1500: training was already old

The surviving record is incomplete, but it makes one thing clear: dog training did not begin with a modern school, a famous trainer, or a piece of equipment.

Xenophon wrote about breeding, raising, and training hunting dogs around the fourth century BCE.

Medieval European writers later described dogs used for hunting, herding, guarding, and companionship, along with methods that ranged from attentive care to practices we would reject today.

This is not a simple march from a cruel past to an enlightened present.

Late 1400s to 1700s: dogs inside colonial power

Dogs were used in human conflict long before European expansion into the Americas. But something changed in this period: they started to be used systematically, within projects of conquest, enslavement, racial terror, surveillance, and dispossession.

Spanish and later European colonial forces used trained dogs against Indigenous people. Dogs were bred and trained to track people seeking freedom and to enforce plantation order. That history has shaped institutions, breeds, training goals, and public images that have traveled into modern-day prisons and policing.

This is one place where the history of dog training and the history of state violence directly meet.

We break this down in detail on the Weaponized Dogs page. The key point is that a training method cannot be separated from what the dog is being trained to do, who is placed at risk, and whose authority the dog is being used to enforce.

The 1800s: work, sport, companionship, and discipline

In the 1800s, industrialization and urbanization changed where dogs lived and what people expected from them.

Hunting, herding, guarding, transport, military work, blood sports, emerging kennel clubs, and life as a household companion all produced different training traditions.

Some of those traditions emphasized physical control and correction. Others relied on food, play, familiarity, and careful selection for a task.

1900 to 1945: institutions and learning science

Police and military dog programs expanded and became more formal.

The world wars accelerated organized breeding, selection, and training for messenger, sentry, tracking and scent work, attack dogs, and other roles. Guide dog programs also grew after World War I, creating a very different model of trained partnership.

At the same time, researchers were formalizing classical and operant learning.

Those discoveries helped explain how consequences, associations, timing, and motivation change behavior.

1940s to 1970s: two powerful inheritances

From the 1940s to the 1970s the world experienced a growing technology of reinforcement-based animal teaching.

Keller and Marian Breland, Bob Bailey, and other applied behavior practitioners developed shaping and marker-signal work across many species.

These methods showed how complex behavior could be built in small, observable steps without relying on physical correction as the teaching engine.

Correction-heavy dog training also remained popular, especially in systems shaped by military, police, and obedience traditions.

Ideas about “rank” and “dominance” also traveled from observations of captive wolf groups into popular explanations of dog behavior.

Later field research showed that a typical wild wolf pack functions like a family group, not a permanent tournament for “alpha” status.

Dogs are not simply wolves in our homes, anyway.

These histories still collide whenever someone says a dog needs to know “who’s boss,” or treats the suppression of a warning signal as proof of “respect”.

1980s to 2000s: reward-based training reaches the public

Reward-based training did not suddenly appear in the 1980s, but books, seminars, puppy classes, video, and eventually the internet made it far more available to dog guardians.

Karen Pryor’s Don’t Shoot the Dog!, clicker training, early-socialization education, and a growing community of “crossover trainers” (who transitioned from using punishment to using reward-based training methods) helped people see that they could achieve incredible training results with kindness.

2000s to now: welfare comes first

The shift we’ve seen now is not merely from one training technique to another.

It’s a change in what even counts as success when we’re “training” our dogs.

These days, we understand that whether a dog performs a desired behavior is just one small part of the training equation.

We know that stress, fear, physical health, emotional state, choice, safety, the dog-human relationship, and the durability of learning matter too.

Comparative research has linked aversive-based training with meaningful welfare risks, and it has not established aversive methods as more effective overall than well-designed reward-based training.

Veterinary behavior and welfare organizations across the world increasingly recommend reward-based methods within the scope of their guidance.

Patterns that keep returning

Visible stillness can be mistaken for understanding. Real dog trainers know that suppression and learning are not the same thing.
Tradition can hide bad choices. “This is how it has always been done” is not evidence that a method is necessary or right.
Authority can be mistaken for expertise. A uniform, a title, a following, or a confident performance does not tell us what a dog experiences, or what they’re actually learning.
Tools can distract from function. The important questions are what the dog is learning, what motivates their behavior, and what costs the training method creates.
Dogs are repeatedly asked to absorb human priorities. Breed, work, family expectations, public fear, entertainment, and state power all influence the behaviors we label as “acceptable” from our dogs.

I did not arrive in dog training outside of this history. I learned from the culture around me, taught what I understood at the time, and changed as the evidence and my experience changed.

I think being honest about that evolution is more useful than pretending any of us began as fully formed perfect trainers. We’re all still learning.

The point of looking back is not to win an argument about who was right first. It’s to see how the ideas we believe in become normalized, and who pays the cost when we stop questioning them.
