TraceOdor™
A new beginning for detection dog training
"It is not the first odor a detection dog learns that determines its future. It is how well the dog understands the process of detection."
That philosophy has guided my work for more than twenty five years. During my career as a police detection dog instructor, operational handler, researcher and international trainer, I have worked with detection dogs in many different disciplines and operational environments around the world. Over the years I have seen remarkable dogs succeed, but I have also seen talented dogs struggle, not because they lacked ability, but because they lacked clarity during the earliest stages of training.
Throughout my career I kept asking myself the same question:
"How can we create more clarity for the dog during the learning process?"
That question eventually became the foundation for TraceOdor™.
TraceOdor™ was not developed because the world needed another training aid. It was developed because I believe the foundation of detection dog training can be significantly improved. The better we teach the process of detection, the easier every operational odor becomes later in the dog's career.
Have we been asking the wrong question?
For decades, detection dog trainers have debated the best way to start a dog.
Should we begin with explosives? Should we use narcotics? Should we use pseudo odors? Should we start with real target substances? Or should we begin with a toy such as a tennis ball or Kong? These discussions have existed for years, but perhaps they all overlook a more fundamental question. Instead of asking, "What odor should my dog learn first?", perhaps we should ask, "Does my dog actually understand what detection is?" Those are two very different questions.
Many dogs eventually learn to recognize an odor. Far fewer truly understand the mechanics of detection. They have never been deliberately taught how to solve odor problems, work independently, trust their nose under pressure or confidently communicate source. These skills are often expected to develop naturally during training, but in reality they deserve to be trained just as carefully as odor recognition itself. This realization became the starting point for TraceOdor™.
The hidden challenges of toy based imprinting
There is no question that toys create motivation. Every experienced trainer has seen dogs become highly enthusiastic when searching for a favorite reward object like a Kong, tennisbal or something else. Motivation is essential, and I would never argue otherwise. However, motivation should never be confused with clarity.
Learning theory teaches us that animals do not isolate individual stimuli. They learn complete situations. Every consistent element present during learning becomes part of the association. If a toy is repeatedly involved during early imprinting, it inevitably becomes part of what the dog learns.
One important concept is overshadowing. Overshadowing occurs when one stimulus becomes more important than another. If the toy is highly motivating and consistently present, it may overshadow the operational odor. Instead of building a strong odor association, the dog develops a more complex association involving the toy, the search routine, the handler and the reward process.
Another phenomenon is blocking. Once a strong association already exists, introducing a new stimulus becomes more difficult because the original predictor already explains the reward. In practical terms, the dog may continue focusing on the established learning pattern rather than fully processing the operational odor.
These are not simply theoretical concepts discussed in academic journals. They influence how efficiently dogs learn every single day.
Dogs do not generalize. They contextualize.
One of the biggest misconceptions in detection dog training is the belief that once a dog has learned something, it automatically transfers that knowledge to new situations.
In reality, dogs are exceptional contextual learners.
A dog may perform flawlessly in the training room and struggle in a warehouse. The same dog may perform perfectly with one instructor but differently with another. Change the flooring, lighting, wind conditions or search pattern and performance may temporarily decline. This is not because the dog has forgotten the task. It is because the dog learned within a specific context. That is why experienced trainers deliberately generalize training across many environments. The dog gradually learns which elements remain constant and which elements can change.
TraceOdor™ supports exactly this process. Because the odor itself remains standardized and consistent, trainers can systematically change everything else. The dog learns that regardless of the environment, the same odor predicts reinforcement. This creates a much cleaner learning process than constantly introducing both new odors and new environments simultaneously.
Learning detection before learning operational odors
Perhaps the biggest shift in philosophy behind TraceOdor™ is recognizing that learning an odor and learning detection are not the same thing. A great detection dog is much more than an odor recognition machine. A great detection dog understands how to search methodically. It knows how to remain motivated during long searches. It learns persistence when odor becomes difficult. It solves complex odor puzzles independently without excessive handler influence. It develops confidence in its own nose and communicates source through a clear, reliable trained final response. Those are detection skills. The operational odor is simply the language through which those skills are expressed.
Once the dog truly understands detection itself, introducing new operational odors becomes significantly easier. Instead of teaching both the odor and the search process simultaneously, trainers can focus exclusively on the new target odor because the underlying detection skills already exist. That is where TraceOdor™ becomes incredibly powerful.
Why TraceOdor™ is different
One of the unique characteristics of TraceOdor™ is that it is not an odor dogs encounter in everyday operational environments. This is not a limitation.
It is a major advantage. Because the odor is completely unfamiliar outside training, dogs begin their detection education in a clean, controlled learning environment free from operational contamination, previous experiences and unnecessary complexity.
It is a major advantage. Because the odor is completely unfamiliar outside training, dogs begin their detection education in a clean, controlled learning environment free from operational contamination, previous experiences and unnecessary complexity.Every successful search strengthens one simple concept. Odor predicts reinforcement. Searching creates success. Independent problem solving is rewarding. Confidence grows. The dog develops a genuine understanding of detection before ever encountering explosives, narcotics, wildlife odors or medical biomarkers. Rather than immediately introducing operational complexity, TraceOdor™ allows trainers to first build exceptional detection mechanics.
The science behind calibration
One of my favorite aspects of TraceOdor™ is its ability to calibrate training. Traditional detection training often varies from one session to another. Small differences in odor quantity, contamination, storage conditions or hide preparation unintentionally influence the difficulty of each exercise. With TraceOdor™, progression becomes measurable. Each odor level has a specific purpose. Each training session can be reproduced. Each instructor can create similar learning conditions.
This level of standardization benefits individual trainers, training schools, police organizations and research programs alike. It also provides stronger documentation and greater scientific credibility should training methods ever require explanation during accreditation or legal proceedings. Consistency creates confidence. Confidence creates better learning.
Six progressive levels of development
The TraceOdor™ system has been designed around the natural development of a detection dog rather than simply reducing odor concentration.
Level 1, Introduction, focuses on Odor Imprinting. The dog discovers that the odor predicts reinforcement while developing curiosity, motivation and enthusiasm for searching.
Level 2, Foundation, develops reliable Odor Recognition. The association becomes stronger across multiple simple environments until recognition remains consistent despite minor contextual changes.
Level 3, Operational emphasizes Search Performance. Dogs begin working realistic search scenarios involving different hide locations, search heights, environmental conditions and distractions while maintaining confidence and motivation.
Level 4, Advanced introduces Sensitivity Development. Odor concentrations become lower, search problems become more challenging and dogs learn increasingly refined odor discrimination.
Level 5, Expert focuses on Trace Detection. Dogs are challenged with extremely small odor quantities requiring patience, precision and advanced odor problem solving.
Level 6, Specialist represents Operational Mastery. Here dogs combine everything learned throughout the program into reliable operational performance under demanding conditions involving minimal odor quantities, complex search environments and realistic operational pressure.
Each level builds upon the previous one, creating a logical learning progression from beginner to highly specialized detection dog.
Designed for everyday trainers
Developing TraceOdor™ required extensive experimentation with different delivery systems. Some methods offered laboratory precision but proved far too expensive. Others were technically accurate but impractical for daily use. The goal was never to create the most complicated system. The goal was to create the most useful system.
Every 10 ml bottle is therefore supplied with two dispensing options.
The standard dropper cap allows experienced trainers to dispense individual drops with excellent control. For trainers who prefer maximum simplicity, each bottle also includes a squeeze dropper cap that reliably dispenses a controlled single drop with minimal effort.
Earlier in my career, while training arson detection dogs, I worked extensively with micropipette tips. Although they provide exceptional accuracy, they also require additional equipment, increase costs and create greater contamination risks through repeated handling.
For most trainers, simplicity and consistency are far more valuable than laboratory complexity. The dilution system allows trainers to create different levels of challenge simply by selecting another progression level. One carefully dispensed drop is enough to produce a meaningful training exercise.
More than a product
One of the most rewarding aspects of introducing TraceOdor™ has been the feedback from experienced detection trainers. Many tell me they genuinely enjoy progressing through the different levels. Lower odor concentrations require patience and repetition before dogs become consistently successful. That gradual progression changes the trainer's mindset. Instead of asking, "Did my dog find it?" They begin asking, "Why did my dog succeed?" "What made this search more difficult?" "How can I create the next learning step?" Those questions represent a completely different philosophy. The trainer becomes less focused on hiding odor and more focused on designing learning. That, in my opinion, is the future of professional detection dog training.
Looking ahead
TraceOdor™ is not intended to replace operational target odors. Operational odors remain essential and always will. They represent the final destination for every professional detection dog. TraceOdor™ simply creates a better road to get there.
It provides a clean, standardized and scientifically structured foundation where dogs first learn the mechanics of detection before transitioning to operational complexity. It gives trainers a repeatable system for training, testing and calibrating detection dogs while improving consistency across individuals and organizations.

The dog must first understand detection itself. For decades we have focused on teaching dogs what to detect. Perhaps the next evolution in detection dog training is teaching them how to detect. That is the philosophy behind TraceOdor™. Not just another odor. Not just another training aid. A science based foundation system designed to build the next generation of exceptional detection dogs. Because great detection dogs are not defined by the first odor they learn. They are defined by how well they understand the process of detection.
