“You’re putting so much pressure on yourself, and that’s impacting your dog.”

Today, our hosts Robin Greubel, Stacy Barnett, and Crystal Wing chat about what they’ve been up to lately, including their recent experience at the Muscatatuck Open, a high-level canine detection seminar known for its complex scent theory drills and immersive training.

They discuss how the seminar’s intense setups—with full-body donor work, long-term odor problems, and unique hide placements—challenged both handlers and dogs in ways that left a lasting impact.

Robin juggled certification tests and a 10-week-old Labrador while Crystal flew straight from early retirement into the dog training world’s version of a dream tour!

The Dames of Detection reflect on the Muscatatuck seminar: a high-level, all-inclusive training camp that delivered not just technically, but mentally and emotionally, as well.

Muscatatuck was a series of complex challenges—from scent voids and convergence hides to managing large source odors. It was, as one student put it, transformational.

Crystal, still raw from leaving her teaching career, shares how her pressure-sensitive dog Radish mirrored her inner state, teaching her the value of emotional regulation in handling. Stacy, working a freshly postpartum dog, found reassurance in her dog’s ability to locate a full-body aid, critical for live-find dogs deployed in unpredictable search-and-rescue scenarios.

Robin Greubel and Crystal Wing return with the brilliant Katylynn Sloan for part two of their conversation on the intersection between chemistry and K9 detection!

“Train with as much variety as often as you can, in the weirdest of circumstances you can possibly get to, with as many groups and as many people as you can.”

Katylynn dives into one of the most misunderstood topics in the detection world: training aids. She breaks down why the term “pseudo” is falling out of favor, replaced by “alternative training aids,” and classifies them into four types: dilution, absorption, mimic, and vigilance. Each has its pros and pitfalls. Mimics, for instance, rely on human interpretation of what’s important for a dog to smell—sometimes right, sometimes not. And vigilance aids? They’re about maintaining search behavior, not the odor itself.

Katylynn also emphasizes the importance of language. As a member of standards boards like ASB and OSAC, she helps shape definitions so handlers, trainers, and scientists are all speaking the same language in courtrooms and classrooms alike. It’s not just about what you know, but how clearly you can explain it. Her advice to aspiring canine scientists? Master problem-solving, communication, and the humility to say, “I don’t know.”

She also touches on the challenges of HRD training, the evolving definitions of “real” odor, and how even “duh” science needs to be written down. Her message to handlers? Train broadly. Generalization is key. Get variety in odors, people, places, and aids—because you never know what the real world will throw at your dog.

Dogs are really good. But they’re even better when guided by thoughtful, curious humans willing to adapt, collaborate, and learn. Katylynn’s passion isn’t just informative—it’s contagious.

“The dogs are so good at what they do, it’s brain-boggling.”

Today, 2/3 of our hosts, Robin Greubel and Crystal Wing, welcome Katylynn Sloan, a chemist with the U.S. Secret Service, to explore the eye-opening intersection of science and canine detection work.

With a PhD in chemistry and years in explosives research, Katylynn brings a fresh lens to how odor behaves, how dogs detect it, and why context matters. She explains how high vapor pressure substances like nitroglycerin contaminate everything they touch, and why containment protocols must evolve.

From calibrating training aids to understanding the unexpected behavior of odor in vehicles, Katylynn stresses the importance of operational realism. Dogs, she explains, learn expectations. If training doesn’t reflect real-world scenarios—like suicide vests or buried explosives—dogs might miss critical cues. She calls for more collaborative studies in generalization, where the difference in one chemical compound might be enough for a dog to disregard an otherwise familiar substance.

Katylynn’s insights aren't just academic—they’re actionable. She champions “train how you operate,” emphasizes the need for diverse training aids, and highlights the gaps in disciplines like HRD, narcotics, and electronics detection. Most importantly, she reminds us: dogs are really good. But it’s the handlers—those who know their dog’s tail twitch or sniff shift means something—that bring science to life.

Science and scent don’t compete. They collaborate. And as Katylynn shows, better understanding leads to smarter training and safer communities. Tune in next time for part two of this fascinating conversation with Katylynn!
