Why I care so much about the materials we use
When people think about detection dog training, they often focus on the dog, the odor, or the reward system. And of course those things are important. But over the years, I learned that there is another piece of the puzzle that many trainers underestimate:
The materials we use during training.
Dogs are not detecting objects. They are detecting odor. More specifically, they detect tiny airborne scent particles called VOCs, volatile organic compounds. That means everything surrounding the odor can influence what the dog learns. The container, the training aid, the cleaning products, even the way equipment is handled can all become part of the odor picture. This is one of the reasons why I became so interested in material behavior and odor integrity.
At DetectionDogShop we try to keep things simple, functional, and honest for the dog. Our philosophy has always been very straightforward: Support the learning process. Don’t interfere with it. That sounds simple, but in detection training it matters enormously.
The dog learns the entire picture
During training, the dog is constantly collecting information from the environment. We may think we are teaching one specific target odor, but the dog experiences much more than that. If training equipment holds old odors, releases strong material smells, or carries contamination from saliva, dirt, or human handling, then those things can slowly become part of the learning picture too.
The dog is never “wrong.” The dog simply learns from the information we provide.
That is why I became increasingly focused on clean odor presentation and neutral materials. Not because I want perfect conditions, perfect conditions do not exist, but because clarity helps dogs learn faster and with more confidence.
Why I use different materials
Over the years I tested many different materials in operational work and training environments. Some materials absorb odor deeply. Others keep odor mostly on the surface and are easier to clean and reset. This is why I often work with materials like stainless steel, glass, PETG, PP, and carefully selected PVC depending on the training goal.
For example, our scent wheels and Direct Odor Imprint stands are made from high-quality stainless steel. Stainless steel is durable, easy to clean, and has very neutral odor behavior. It stays consistent over time, even after intensive use.
The PETG we use has also become one of my favorite materials because it is non-porous, chemically stable, and easy to maintain. It gives trainers a very reliable and consistent training experience.
Wood, on the other hand, behaves very differently. Wood absorbs odor deeply into the material, making it difficult to completely clean. That does not make wood “bad,” but it does make it less suitable for situations where odor clarity and consistency are important.
I think it is important to be honest and balanced about materials. There is no perfect material. Every material has strengths and limitations. What matters is understanding how those materials influence the odor picture the dog experiences.
Why I developed and use ODDs
One of the tools I use extensively in my training systems is the ODD, the Odor Delivery Device. I originally started working with ODDs because I wanted more control over odor presentation and contamination. In many training environments, odors spread too easily through the search area. Residual contamination builds up over time, and eventually the training picture becomes unclear for the dog.
ODDs help solve that problem.
They protect the odor source while still allowing airborne odor to escape naturally. This keeps training cleaner and more controlled. It also protects fragile, toxic, or sensitive odor sources from unnecessary contact.
What I love most about ODDs is their flexibility. Trainers can bury them, hang them, place them underwater, mount them on vehicles, or hide them in almost any environment. The compact design makes it possible to create realistic and creative training setups without contaminating the entire area.
Our ACT! ODDs are designed to integrate seamlessly with our scent wheels, DOI stands, and lineup systems so trainers can create a complete and consistent training environment. Some trainers also choose magnetic ODDs, which allow even more creativity during vehicle searches and operational-style training scenarios.
For me, ODDs are not just containers. They are tools that help create cleaner communication between the odor and the dog.
The most overlooked part of detection training
One of the biggest contamination sources in detection work is not the environment itself. It is us. Human scent, saliva, grease, dirt, and bacteria slowly build up on training equipment. Over time, this changes the odor picture dramatically. Many trainers do not notice it happening because the contamination builds gradually.
That is why cleaning became such an important part of our philosophy.
We developed a special cleaning spray specifically for detection training equipment because many standard cleaning products leave strong residual odors behind or damage sensitive materials. Our spray is designed to clean detection equipment quickly and safely without introducing unnecessary scent contamination. It is fragrance-free, dye-free, non-toxic, and compatible with materials like stainless steel, PETG, glass, PP, and PVC.
I personally love the small 50 ml bottles because they are easy to carry during training sessions. Trainers can quickly clean targets, ODDs, scent wheels, and training equipment directly in the field. Fast cleaning means cleaner odor presentation and more consistent learning for the dog.
The spray also has excellent cleaning power and works quickly against contamination while remaining safe for the equipment itself. Again, the goal is simple: Reset the equipment back to a neutral state.
Detection training does not need perfection
One thing I learned after more than 30 years of operational dog work is this: You will never create a completely sterile training environment. There will always be airflow, humidity, temperature changes, human contamination, environmental odor, and countless invisible influences around the dog.
And that is okay.
The goal is not perfection. The goal is clarity.
When we choose materials carefully, maintain our equipment properly, and think about odor behavior, we make the learning picture cleaner and easier for the dog to understand. Confident dogs learn faster. Clear training creates confident dogs.
Final thoughts
At the end of the day, my philosophy is very simple. Good training equipment should help the dog succeed, not create unnecessary confusion.
That is why I focus so much on:
- Neutral materials
- Functional design
- Clean odor presentation
- Consistent setups
- Easy maintenance
Everything we develop at Detection Dog Shop is built around those ideas.
Because when the odor picture becomes cleaner and more honest, dogs perform better, trainers become more consistent, and the entire learning process becomes clearer for everyone involved.
