Treats or Tugs? The 2026 Copenhagen Study That Says Your Dog Training Style Reveals Your Ethics

Positive reinforcement is more than a technique — Copenhagen researchers say it reflects how owners view animals.

When you ask your dog to sit, what happens next? Do you slip a treat from your pocket, or do you tug the leash until they comply? According to a May 2026 study from the University of Copenhagen, that small choice is not just about effectiveness. It is a window into your ethics.

The research, led by Professor Peter Sandøe and conducted with colleagues at the University of Edinburgh, surveyed 500 American dog owners about both their training methods and their underlying beliefs about animals. The pattern that emerged was unmistakable: how you train your dog reveals how you think dogs — and animals in general — deserve to be treated.

The Three Ethical Tribes of Dog Owners

The researchers sorted respondents into three groups based on how they answered statements about animal use:

1. Anthropocentric — animals exist for humans to use.
2. Animal welfare — humans may use animals, but owe them good lives.
3. Animal rights — animals have moral standing comparable to humans.

Owners in the first camp were significantly more likely to reach for verbal reprimands or physical corrections — yanking the leash, scruff-grabbing, or shouting "no." Owners in the second and third camps leaned heavily on treats, toys, and verbal praise.

"Training is not a neutral activity. It is an activity in which the owner's view of the animal becomes apparent." — Professor Peter Sandøe, University of Copenhagen

A treat in the palm: the most common reward across all three ethical groups, but used most consistently by welfare-oriented owners.

Why This Is Not Just About Learning Theory

For decades, the debate between "balanced" trainers (who mix corrections with rewards) and "force-free" trainers has been framed as a scientific argument about what works. The Copenhagen team argues that framing misses the point. People do not actually choose methods based purely on evidence. They choose them based on what they already believe a dog is.

That is why the same peer-reviewed studies on canine learning can be cited by both sides, and neither side budges. The disagreement is moral, not technical.

This finding lines up with our earlier reporting on how genes shape which dogs make it through guide-dog training — even when nature stacks the deck, the human in the partnership still decides whether to coach with kindness or coerce with pressure.

What the Numbers Looked Like

Across the 500 respondents:

• Positive methods (treats, toys, praise) were the most widely used overall.
• Punishment-based methods were used less frequently, but were heavily concentrated among owners who agreed with statements like "animals are here for human benefit."
• Welfare-oriented owners reported the highest rates of clicker training, food rewards, and play-based reinforcement.

The data collection was carried out by Tracy Weber at the University of Edinburgh, with the ethical-orientation scale developed by the Copenhagen group — the same instrument previously used to predict whether shoppers buy welfare-labeled pork.

Loose-leash walking, taught with rewards, is associated with owners who view dogs as partners rather than property.

How to Audit Your Own Training Style

You do not need a 30-question survey to figure out where you land. Ask yourself three honest questions on your next walk:

• When my dog ignores a cue, is my first instinct to add pressure (a leash pop, a louder voice) or to add value (a better treat, more distance from the distraction)?
• Do I think of training as teaching a partner or as correcting a subordinate?
• When my dog gets it right, do I mark and reward — or do I just expect compliance?

If most of your answers lean toward pressure and expectation, the Copenhagen study suggests your toolkit reflects an anthropocentric view. That is not a moral verdict — but it is worth knowing about yourself.

The Welfare Case for Going Positive

Beyond ethics, there is a growing body of veterinary evidence that punishment-based methods raise stress hormones and damage the human-dog bond. Stress also undermines the very things owners are trying to fix — anxiety, reactivity, and over-arousal — which is part of why senior dogs in our coverage of the 2026 Adelaide CCD class study responded so well to gentle, group-based positive training.

Reward-based training also pairs naturally with the kind of preventive care we cover in our dog health & wellness guides: a relaxed dog tolerates handling, vet visits, and grooming with far less drama.

Praise and gentle handling — the cornerstone of welfare-oriented training, and especially effective with rescue dogs.

What This Means for New Puppy Owners

If you are bringing home a puppy this summer, the Copenhagen findings are a quiet invitation to think about why you will train the way you train — not just how. Our puppy training guides default to reward-based methods for exactly the reasons this study makes visible: they work, they protect welfare, and they reflect a view of dogs as social partners rather than tools.

For owners of toy and companion breeds — where leash corrections carry a real risk of tracheal damage — the case is even stronger. See our recent piece on the 2026 Pomeranian boom for breed-specific harness and handling advice.

The Bigger Picture

Sandøe is careful to note that the 500-person sample is not representative, and the study cannot tell us how common each ethical orientation is in the general public. What it can tell us is that training method is not a free-floating technical choice. It is downstream of values.

That makes the next time you reach into your treat pouch — or your collar — a small ethical act. Worth doing on purpose.
