When passion becomes belief: A wake-up call for the K9 world
It has been a remarkable week in the K9 world. A week that challenged long-held beliefs, exposed weaknesses in popular training systems, and perhaps shook a few egos along the way. I am writing this blog not from a place of judgment, anger, or superiority, but from a genuine desire for honesty, collaboration, and progress. That requires courage in a world where people often become emotionally attached to a single method, ideology, or “system.” The dog world deserves better than polarization. It deserves curiosity. It deserves transparency. And above all, it deserves integrity.
The problem Is not the dog
Dogs are extraordinary animals. Their abilities continue to amaze us every single day. Their noses, problem-solving skills, resilience, and willingness to work with humans are truly remarkable. The real problem is often us.
For years, science has shown that handlers can unintentionally influence their dogs through subtle cues, expectations, body language, and behavioral patterns. Yet every time new research challenges popular beliefs, many people respond not with reflection, but with resistance. Instead of asking: “What can we learn from this?” they ask:
“How can we defend our system?”
That mindset blocks growth. The irony is that science is not attacking dog trainers. Science is trying to help us become better trainers.
The research that sparked discussion
Recently, Vera Volmary published the study:
Initial trail selection in mantrailing dogs under double-blind field conditions: a statistical evaluation of scent discrimination performance.
The findings did not surprise me. Under truly double-blind conditions, where neither the handler nor the observers knew the correct trail, the success rate was approximately 20%. Some people immediately respond: “But 20% is still better than nothing.” The uncomfortable reality is that 20% also corresponds with expected chance levels. That should make all of us pause and reflect.
Not because dogs are failing. Not because handlers are bad people. But because humans are often influencing outcomes without realizing it. And if our training systems collapse under proper double-blind conditions, then we must ask ourselves difficult questions.
A difficult question for influencers and trainers
If your business model is built around trailing seminars, hard-surface tracking workshops, or “exclusive systems,” this may be the moment to honestly look in the mirror.
Are you truly trying to improve the dog world? Or are you protecting a business model?
That question is uncomfortable, but necessary.
Today, social media rewards confidence far more than truth. Beautiful videos, dramatic success stories, emotional music, and clever marketing create the illusion of expertise. But impressive footage is not the same as scientific validation.
Working your own track while knowing every turn, every corner, and every contamination point tells me very little. If your work is not double-blind, then the results are not meaningful to me. That may sound harsh, but operational reality is harsh too. Lives, investigations, reputations, and legal outcomes depend on truth, not on edited social media content or workshop hype.
Simplicity is often the sign of real understanding
Over the years, I have learned something very important: If someone cannot explain something simply, they often do not fully understand it themselves. True expertise does not hide behind mysticism, vague language, complicated rituals, or “special secrets.” Real knowledge becomes clearer through simplicity. Science does not destroy dog training. Science strengthens it.
And yes, science will sometimes debunk methods we once believed in. That is not an attack. That is progress. The strongest trainers are not the ones who desperately protect old ideas. The strongest trainers are the ones willing to adapt when evidence changes.
The kong debate and operational reality
Another important discussion this week involved the early findings from research by Paola Tiedemann regarding the use of Kong as a target odor. Many years ago, I stopped using Kong as a target odor in operational detection training. Not because it was unpopular, but because I saw practical, tactical, motivational, and legal problems developing.
One of the concerns was overshadowing and the extremely strong vapor pressure of Kong odor. But there was another serious issue: What happens in court when a defense lawyer demonstrates that compounds found in Kong are also present in many everyday products and environmental materials? That matters!
Especially when probable cause and criminal investigations are involved. This is exactly why operational dog training must be approached with scientific rigor rather than emotional attachment.
Overwhelming odor profile
The reality is that many dogs trained extensively on Kong become conditioned to a loud and overwhelming odor profile. That creates problems when transitioning to low vapor pressure operational targets. Yet despite these concerns, the hype continued for years, often promoted by people with little or no operational experience.
The brick wall illusion
One of the most common examples is the famous “brick wall Kong search.” It looks impressive on video. A dog intensely searches a wall, works odor cones, appears highly motivated, and finally locates a hidden Kong reward. Audiences applaud. Handlers feel inspired. Workshops are sold. But we should ask ourselves a serious question:
What exactly are we teaching the dog?
In many cases, we are not solving motivational problems at all. We are reinforcing them. When dogs lose motivation on difficult low vapor pressure targets, some trainers return to the wall search with Kong because the dog becomes highly excited again. But this does not truly improve operational capability. Instead, it often strengthens the dog’s preference for loud, easy, highly rewarding odor pictures.
The dog learns:
“If I disengage from difficult odor, eventually I will get back to the exciting Kong game.”
That is not operational resilience. That is reinforcement of avoidance and dependency on easier odor work. And there is another issue many people ignore. During these wall searches, handlers often know exactly where the Kong is hidden. The moment the dog shows interest near the correct area, the Kong is thrown as a reward.
But what does that mean? It means the handler is not blind to target placement. And if the handler knows the location, subtle cueing can happen, consciously or unconsciously. This is precisely the same concern raised in double-blind trailing research. Handlers influence dogs far more than most people realize.
Operational reality is very different
Real operational detection work is not a social media exercise. Operational dogs do not get unlimited time to search one small section of a wall while a crowd watches. They must make decisions quickly, under pressure, in contaminated environments, often while working extremely difficult odor pictures with very low vapor pressure. And contamination itself creates another problem.
Ignoring contamination?
When trainers repeatedly move Kong rewards across different locations on the same wall, dogs can start learning that residual contamination has little meaning because the actual reward keeps changing position. That can unintentionally teach dogs to ignore important contamination information rather than properly process it. Again, this does not mean nose work games are bad. Far from it. Dogs love these activities. Handlers enjoy them. They create engagement, enrichment, and fun. But operational claims require a completely different level of scrutiny.
The pattern we keep repeating
What fascinates me most is not the research itself. It is the reaction to it. We saw the same pattern years ago when Lisa Lit published her research Handler beliefs affect scent detection dog outcomes. Handlers unknowingly influenced their dogs during searches. Instead of embracing the opportunity to learn, many attacked the scientist, the methods, and the study design.
And now history repeats itself again. Whenever science challenges belief systems, some people become defensive because their identity, reputation, or income depends on those beliefs remaining untouched. But science is not the enemy. Science is the mirror. Mistakes are data points.
This is not about destroying enjoyment
Let me be very clear. If you and your dog enjoy trailing, tracking, scent games, nosework or detection sports, wonderful. Keep doing it. Enjoy every moment together. Nosework is enriching, fascinating, and deeply rewarding for dogs and handlers alike.
Also the research of C. Duranton and A. Horowitz with the title "Let me Sniff! Nosework induces positive judgment bias in pet dogs' was clear about the wonderful effects on dogs when they are allowed to do all sort of nose work games. On of their statements is that nosework increases dogs 'positive judgement bias or optimism' and olfaction-based activities contribute to dogs welfare.
So science explained us that nosework will give dogs a more positive look at life. But enjoyment and operational claims are not the same thing. There is a major difference between:
-
enjoying a sport,
-
selling entertainment,
-
and claiming operational reliability in criminal investigations or missing person cases.
That distinction matters enormously. Because giving false hope to families, investigators, or courts is not harmless.
The danger of ego in the dog world
One of the greatest dangers in the modern K9 industry is not poor methodology. It is ego. Some trainers genuinely do not know the latest science. They may be unaware of concepts like Clever Hans effects, handler cueing, contamination patterns, or expectancy bias.
But others know. And that is where integrity becomes important. If science debunks your protocol, your system, or your claims, you have two choices:
-
Adapt and grow.
-
Attack the science and protect the brand.
Real professionals evolve. The dog world needs fewer gurus and more critical thinkers.
Integrity matters more than popularity
As a young boy growing up in a family of entrepreneurs, I learned that business should be built with honesty, sustainability and quality. Later, as a police officer, integrity and facts became non-negotiable parts of my work. And throughout my career in the K9 world, I have tried to focus on innovation, curiosity, and improving systems, not protecting ideology.
Yes, I have seen impressive marketing and beautiful demonstrations. But I have also seen handlers unknowingly cue their dogs. I have seen trainers oversell unrealistic capabilities. And I have seen business models built around telling people exactly what they want to hear. That is dangerous. Not only for handlers. Not only for police agencies. But also for the credibility of the entire dog community.
The way forward
The future of the K9 world should not be built on cults, ego, or blind loyalty to methods.
It should be built on:
-
transparency,
-
double-blind validation,
-
scientific curiosity,
-
operational honesty,
-
and open dialogue.
Science will continue to challenge old beliefs. And that is a good thing. Because progress only happens when we are willing to question ourselves. The strongest trainers are not those who never change their minds. The strongest trainers are those who care more about truth than about being right.
