What to listen for:
“We are very good at selectively breeding, obviously to drive change in the shape, but not necessarily to drive performance.”
Robin and Stacy continue their conversation with Dr. Lindsay Waldrop, a Chapman University fluid dynamicist who secured Navy funding to build the world's largest collection of micro-CT-scanned domestic dog skulls.
Dr. Waldrop discusses why skull morphology offers no reliable prediction of scent detection performance. Breed shape, muzzle length, turbinate density… she says that none of it predicts which dogs will find the tin.
She cites a study that scanned roughly 125 museum skulls, landmarked them geometrically, and mapped the variation against breeds with historically scent-focused versus bite-work roles.
The answer was flat. No morphological feature sorted reliably by task. A Labrador has approximately the same mechanical bite leverage as a Malinois, yet nobody uses Labradors as patrol dogs, because that's behavior and genetics, not skull shape.
And the pug? In a separate Nathan Hall study, the pug outperformed German shepherds on a basic odor detection task. The greyhounds couldn't be bothered to participate.
Bloodhound ears sit in the same category. It’s a story told often enough to feel true, but never actually tested. From a fluid dynamics standpoint, Stacy says she'd be shocked if those ear flaps were routing scent toward the nose in any meaningful way.
The same applies to the claim (circulating on social media) that early scent initiation protocols increase the number of olfactory receptors in developing puppies. Specific, testable, evidence-free.
It’s important to distinguish science-based reasoning versus evidence-based claims. Dr. Waldrop’s flow visualization work is science-based, informed by expertise, probably accurate, not publishable as proof. But claiming a puppy protocol rewires the olfactory system is an evidence-based claim with almost no data behind it.

“We're such dumb visual monkeys. We can't process information any other way except for visuals; whereas the dogs have their brain structured around scent.”
Dr. Lindsay Waldrop, a Chapman University fluid dynamicist whose dissertation explored how crabs sniff odor out of water, has spent recent years turning that expertise toward dogs. Our hosts, Robin Greubel and Stacy Barnett, chat all things scent with her in this episode of K9 Detection Collaborative.
Her central argument dismantles the "scent cone". Typically, handlers picture it as smooth and continuous, like an ice cream cone. However, real odor plumes are discontinuous, sheared into filaments by advection, the same way food coloring resists mixing into thick batter.
A dog's nose can land dead center in a plume and find nothing, or catch a stray filament far from the source and read it as close.
Lasers and cooled smoke, not hot smoke bombs that generate their own rising thermal current, are Waldrop's preferred way of making that invisible turbulence visible.
Dr. Waldrop brings up a rebreather study (just one of a few eye-opening studies she cites throughout the conversation), which suggests live-find and cadaver dogs may be solving entirely different fluid problems. That’s because a living person's breath gets lofted skyward while decomposition odor clings near the ground.
That said, Dr. Waldrop’s field has limits, which she fully acknowledges. For instance, full environmental modeling is often too slow to beat a simple flow-vis demo, and the real frontier is closer collaboration with the handlers who know which questions are worth asking. Tune into the next episode of K9 Detection Collaborative for part 2 of this fascinating conversation!

What to listen for:
"If you are not doing search and rescue for the right reasons, you need to look in the mirror. Because it is not about you, and it's not about your dog."
Today, our hosts, Stacy Barnett and Robin Greubel, have set the dogs aside (mostly!) to talk about something that affects every handler who has ever posted a training video, shown up to a webinar, or scrolled too far down a comment thread. They're calling it the “toxicity tax,” and they've come to argue it's being paid at every level of the canine world, from nose work titling to search and rescue callouts.
The online world, particularly on social media, strips away tone, facial expression, and social consequence, leaving text that people read with whatever emotional state they're already carrying.
Robin references the book Don't Feed the Elephants! when she explains that “Avoidaphants” are everywhere in teams that have never sat down to agree on how they want to communicate.
Stacy offers sport as a mirror for SAR. The moment you start watching other dogs instead of your own, you've already lost the run. Comparing your dog's time, your team's reputation, your cert against someone else's is a fast road to a distracted, ineffective search.
The mission has to be bigger than the handler.
Robin and Stacy agree that training is not a recipe. Dogs are individuals, methodology debates serve nobody, and a perfect run every time is evidence of stagnation.
What serves the dog, and the missing person, is efficient, effective teamwork built inside a culture that gives grace when the wheels come off.

“Everything I knew about my dog that I thought was true a week ago is no longer true. I have to reset my baseline and go, ‘Who are you today?’”
Our hosts, Robin Greubel and Stacy Barnett, pick up the conversation with Joy Brenner of K9 Medic. This time, they’re talking about turning everyday crate time into deliberate heat acclimation.
Joy explains that many handlers keep cars too cold, creating a dangerous temperature “delta” that leaves dogs physiologically unprepared for field work. Instead, she programs her dog Storm by running the car just below panting level during downtime, shrinking that gap and building real biological tolerance. This is exactly what military and kennel dogs get by living outside.
High-fidelity monitoring makes it safe.
Cheap baby cameras with temperature readouts and night vision let handlers watch remotely and check every 20 minutes during high-risk windows (right after work or when AC fails) because “temperature has momentum” and cars remain a leading cause of preventable heat death.
They discuss crate fans, breathable pads, reflective car covers, and the limited but situational value of cooling vests (ask your dog). Another practical tip is to do two-minute “t-checks” (transitions checks) at every car entry, with copious water and paw inspections.
Whether traveling from Iowa’s sweaty season to mountain fires or simply switching seasons, it’s important to reset baselines daily and support the dog you actually have today.

“At the end of the day, taking care of our dogs is everyone’s job.”
Our hosts, Robin Greubel and Stacy Barnett, talk with Joy Brenner of K9 Medic about looking at canine first aid not just from the perspective of flashy trauma response, but that of the quiet, daily work of truly knowing your dog.
Joy, who began in human wilderness and tactical medicine, built K9 Medic to teach handlers, medics, and even surgeons pre-hospital care tailored to real field conditions.
High-fidelity mannequins like K9 Hero and Diesel train teams on military-identified killers such as tension pneumothorax, but Joy repeatedly returns to the bigger truth: heat, not bullets or dramatic wounds, is the top preventable cause of death for every dog, whether tactical, SAR, sport, or pet.
Her Handler 2.0 program trains handlers in “dog speak”: reading baselines, scaling panting, tracking work/rest cycles, and spotting when a dog is no longer compensating.
They bust old myths (alcohol pads, ice-pack vasoconstriction fears, over-cooling shock) and stress rapid cooling to skin level while stopping just above normal, so temperature momentum carries the dog safely home.
Structured observation prevents emergencies, improves performance, and turns both handlers and medics into better advocates, because taking care of our dogs is everyone’s job! Tune in to the next episode for part two of this important conversation!

Our hosts, Robin Greubel and Stacy Barnett, chat about a peculiar kind of self-deception. The kind that costs years of training, thousands of dollars, and sometimes the well-being of both dog and handler. They call it beer goggles: the tendency to see the dog we want rather than the dog standing in front of us.
Robin talks about Flash, her Lab who simply doesn't bark. Selectively bred for quiet patience in a hunting blind, Flash is temperamentally ill-suited for the alert-dependent demands of FEMA disaster work.
It's a genetic reality rather than a training gap, and knowing the difference is the whole game.
Beer goggles run in every direction. A handler can overestimate a dog's capacity, grinding for years toward a certification the animal was never built to earn. But the distortion runs the other way too. It’s easy to mistake a sensitive dog who has gained real confidence for one who still needs to be handled with kid gloves, and failing to update that mental image.
Robin's young Raven is a sharp example. written off as food-averse and agility-reluctant, she turned explosive once Robin stopped pushing food and started throwing toys for her to hunt.
Stacy’s current dog was acquired in 2020 as a sport prospect, redirected to wilderness search and rescue, and is now being painstakingly rebuilt for urban USAR work. The genetics were always there, but the USAR-specific foundations needed filling in.
As a trainer, you need to be asking, honestly, whether you're doing this for the dog or for yourself, and whether the gap you're looking at is closeable. A starter dog, like a starter home, is nothing to be ashamed of!

Our hosts, Robin Greubel and Stacy Barnett, welcome Bob Deeds back to debrief the first-ever chicken workshop hosted at Robin's farm.
Bob, drawing on the legacy of Keller and Marian Breland and Bob Bailey, the operant conditioning pioneers behind Animal Behavior Enterprises and the IQ Zoo, explains that the chicken workshop isn't really about chickens at all!
White Leghorns, selected for their speed and reactivity, are a crucible for the trainer, forcing observational precision, mechanical timing, and real-time decision-making that slower species simply can't demand. The group that gathered at Robin's farm was a genuinely mixed bag: a horse trainer, professional detection handlers, a pet dog trainer who also teaches others, and a sport dog handler who arrived feeling self-conscious about her credentials.
By the end, that trainer was unrecognizable in the best way. Her confidence transformed, her mechanics sharpened, her sense of belonging earned.
What the hosts return to again and again is the downstream effect of students reaching out weeks later, saying they finally had the words to explain a dog's behavior to a client, or that they rewrote a puppy class mid-workshop. That's the whole point.

"Unless you have a dog who is engaged with you, you can't build that relationship. And you can't get through distractions. It's impossible.”
Today, our hosts, Robin Greubel and Stacy Barnett, are talking relationships. Specifically, what it actually means to have one with your dog when the pressure is on. They argue that a real relationship isn't Kumbaya, it's the thing that keeps a dog still on a medic's table and calm on a tailgate in Texas!
Robin describes bringing her working dogs, the Labs Flash and Flare, and her Malinois, Nico, to a USAR medic training where the team practiced catheter placement and restraint under veterinary supervision.
Flash and Flare wrestled the medics into a genuine upper-body workout. Nico simply lay still, held by a raised finger and three years of earned trust. Meanwhile, Stacy recounts her wilderness air scent SAR dog, Prize, enduring an improvised dewclaw removal on a truck tailgate during a study at Texas Tech, stoic because the years of shared work had already made Stacy's presence genuinely reassuring.
Relationship and engagement are not soft concepts but functional prerequisites.
Without engagement, a dog cannot regulate arousal. Without regulated arousal, a dog cannot sustain focus through distraction. Without focus, a search develops holes, and holes erode the handler's ability to call an area clear with confidence, whether in competition or in the field.
Stacy and Robin are careful to frame searching not as a single behavior but as a layered chain requiring relationship, engagement, arousal, focus, and what Stacy calls the reinforcement event.
That means a full celebratory interaction, not just a cookie, that imprints the preceding behavior far more deeply.
Reading a learner, distinguishing processing from disengagement, hunting from scavenging: these are the observation skills that underlie everything else.

What to listen for:
Our hosts, Robin Greubel and Stacy Barnett, break down why "opting out" has become a buzzword that may obscure more than it reveals. While the term sounds empowering (giving dogs agency and choice), they argue it can become a self-congratulatory label that prevents handlers from addressing underlying training gaps.
Stacy shares the story of 15-year-old Ray, who "opted out" of FEMA disaster work but later excelled at narcotics detection on a short lead. Ray didn't dislike detection work. Rather, she disliked working independently, far from her handler. Had Stacy recognized this earlier, she could have placed Ray in close-proximity disciplines like historic human remains detection instead of washing her out entirely.
Robin recounts how one of her own dogs initially refused to search even three boxes in his front yard due to environmental overwhelm. But rather than accepting "he's opting out," she methodically built confidence through smaller areas, easier hides, and massive reinforcement. She eventually produced an elite champion! The key was asking why and adjusting the training plan, not accepting a vague opt-out label.
They warn against the variable-reinforcement trap, in which dogs train handlers by occasionally succeeding, keeping handlers stuck in ineffective patterns. Stacy describes Dash's trained "collar-itch" behavior: a displacement signal she accidentally reinforced by making hides easier each time he scratched.
Robin and Stacy do believe that legitimate opt-outs exist. Pain, slick floors, and overwhelming environments are just some of them. But these require specific diagnosis, not broad constructs.
They advocate observable behavior analysis over anthropomorphic interpretations. This means that handlers need to teach opt-in through thoughtful progression rather than celebrating opt-out as a virtue.

In the second half of the conversation with Dr. Jennifer Essler, our hosts, Robin Greubel and Stacy Barnett, discuss her current research and future goals bridging academic science with real-world handler expertise!
At SUNY Cobleskill, Dr. Essler's conservation work demonstrates how detection dogs fill practical niches. Her Round Goby project (tracking invasive fish from the Black and Caspian Seas) uses dogs for water sampling rather than locating individual fish.
This mirrors eDNA methodology but delivers immediate field results instead of days of laboratory processing. Dogs trade some sensitivity for real-time assessment, making them viable alternatives when speed matters. The project's success has attracted government conservation agencies interested in applying dogs to other invasive species like hydrilla plants and certain crawfish.
Her Penn Vet ovarian cancer research revealed the limitations of lab-based detection. While dogs successfully identified cancer in blood plasma, clinical deployment was never the goal. Instead, the objective was helping develop electronic detection systems.
The fundamental problem is that even superstar dogs have off days without visible behavioral indicators explaining poor performance. Unlike field work, where handlers notice changes, lab settings offer no safety net for medical diagnosis. Repetitive scent wheel searches also eventually bored excellent performers into retirement.
That shows all the difference between detection work and examination work.
Dr. Essler's future priorities center on quantifying practitioner expertise. That’s documenting how experienced trainers accurately assess young dogs through seemingly instinctive judgments.

Our hosts, Robin Greubel and Stacy Barnett, sit down with canine cognition researcher Dr. Jennifer Essler. She unpacks her journey from coding Capuchin monkey videos in a windowless lab to studying fairness in wolves and dogs.
Starting with music studies before discovering comparative psychology, Essler's academic trajectory took her from Georgia State's primate labs to hand-raised wolf packs in Vienna's Wolf Science Center.
It’s a unique research environment that controls for lifestyle differences between wolves and dogs by raising both species identically in packs. As a result, you can isolate domestication effects from environmental variables. The wolves, however, proved far more challenging subjects than primates, requiring complete experimental apparatus redesigns after initial safety failures.
Her inequity aversion research uncovered pretty interesting species differences: wolves, like primates, showed quality sensitivity by refusing to work when partners received superior rewards.
Dogs, conversely, accepted any reward as long as they received something, possibly reflecting their domestication-driven tolerance for human-directed work, or their reduced attention to partner outcomes.
Robin, Stacy, and Dr. Essler discuss the practical implications this finding has for multi-dog training scenarios and reinforcement strategies.
Essler's transition to Penn Vet Working Dog Center brought her expertise to practical applications: ovarian cancer detection, COVID-19 screening, and spotted lanternfly detection. All while developing behavioral assessment batteries.

“Trust your dog, but trust your training first.”
Our hosts, Robin Greubel and Stacy Barnett, welcome back veteran USAR handler Bob Deeds to talk about the artificial divide between working dog and sport detection communities, and why both sides desperately need each other!
Bob shares his journey from FEMA disaster work into nose work, leading into his innovative "geo-scenting" protocol. This hybrid sport combines geocaching with scent detection using clove oil, specifically chosen to avoid the venue-hopping confusion he observed in sport handlers who switched between organizations.
Sport handlers often remain clique-ish, loyal to single venues (K9 Nose Work vs. NACSW) despite identical underlying science. Bob advocates aggressively for cross-training, noting how watching elite sport handlers transformed his leash skills after a Belgian trainer bluntly told him they "sucked."
Meanwhile, working dog handlers can learn environmental assessment and body language reading from sport competitors operating under time pressure. Bob describes sport handlers' eyes "scanning like machines" upon room entry.
He also considers puzzle work as the great equalizer. He recounts how a struggling student's reactive Standard Poodle transformed after two weeks of pure puzzle training.

What to listen for:
Our hosts, Robin Greubel and Stacy Barnett, explore how drive, motivation, arousal, and focus work together as an integrated system—rather than isolated traits—to create elite performance.
Using a car engine metaphor, Robin explains drive as the engine size or “genetic horsepower” a dog is born with. It’s fixed hardware that defines inherent desire for the work. Motivation is the fuel, built through reinforcement history. Even the biggest engine won’t run without gas, and Stacy stresses that fuel quality matters: powerful, varied reinforcers outperform “cheap” rewards, while poisoned reinforcement can stall performance entirely.
Arousal is the fuel’s octane—too high and the engine overheats, too low and performance lags. Robin describes arousal mobility as training dogs to work across a wider range, smoothly transitioning between high excitement and calm control without corrections.
Focus and engagement are the steering wheel and pedals. Without them, balanced drive, motivation, and arousal just mean “going fast into a wall.” Engagement channels intensity into productive teamwork.
Examples like drive-capping passive alerts versus drive-leaking bark-and-hold behaviors show how training strategies must adapt to balance these elements. The takeaway: performance problems aren’t about lacking drive alone, but about managing the full system.

Our hosts, Robin Greubel and Stacy Barnett, welcome veteran USAR handler Bob Deeds, whose journey from compulsion-based training to positive reinforcement transformed both his career and the field itself!
His career trajectory spans volunteer search and rescue in the early nineties through Texas Task Force One, where he deployed to the World Trade Center with his partner, Kenzie.
The devastating loss of Kenzie in a 2007 training accident nearly ended his career until his friend Sonja Heritage called at 2 AM with a powerful message: quitting meant Kenzie died for nothing.
Bob credits Bob Bailey's chicken workshops as the single most transformative experience for his training mechanics. The fast-paced chickens force observational skills development whether trainers want it or not. Those mechanical skills translated directly to his dogs: when his Malinois Remy would nip holes in Bob's shirt from frustration over poor timing, Karen would smile knowingly.
The dog was using positive punishment to remind Bob to pay attention to delivery, timing, and curriculum!
Now teaching directionals to pet dog owners and planning chicken workshops with Robin in Iowa, Bob teaches that directional control isn't about perfect patterns, but recovery.
As handler Shirley Hammond told him after his first FSA certification, disasters aren't perfect, and recovery from mistakes matters most!

Our hosts Robin Greubel and Stacy Barnett explore generalization as the foundation of reliable detection work.
Together, they reveal generalization as extending far beyond simple obedience across locations. It encompasses odor variability, environmental context, behavioral chains, and handler presentation.
They explain how explosive and narcotic sources vary like chocolate-cake recipes: different manufacturers, cutting agents, and absorption materials create distinct odor profiles.
Dogs trained on limited sources may fail to recognize the "same" target odor prepared differently. That’s why handlers must expose dogs to diverse training aids and seek out other teams' materials.
Next, they talk behavioral generalization. Does "search" mean the same thing in a familiar training field versus a novel parking lot, rubble pile, or aircraft? Robin and Stacy stress that context cues (vehicles, wilderness, buildings) and environmental distractions require deliberate proofing so dogs maintain focus regardless of setting, weather, or ambient noise.
Robin describes her area-search class methodology, which emphasizes that handlers can proof refind behaviors solo by generalizing the chain across handler positions. You could even do jumping jacks or lie turtle-like after falling into a hole.
The goal is stimulus control, which means the cue triggers the behavior everywhere, every time.
Our hosts warn against training disengagement by repeatedly working in overly distracting environments (woods full of "trail mix") without first building a clean chain in controlled settings like big-box stores with clean floors.
If dogs routinely self-employ or search lackadaisically, handlers must assess whether hides exceed the dog's skill level, reinforcement is insufficient, or engagement was never properly conditioned.
Their green-eggs-and-ham framework captures the essence of generalization: master the skill (row your boat), then generalize it everywhere (here, there, everywhere).

“[Being a part of] this podcast terrified me. Putting myself out there was so vulnerable, and I felt like it was such a big risk for you guys, as well. I’m so thankful. I’m glad you made me, but I’m also going to say I’m glad that I did it because in the end, I had the final say in buying the microphone and the headset.”
After 151 episodes, Crystal Wing says goodbye (or rather, seeya later) to the K9 Detection Collaborative family, and lets us know the exciting things she has in store in the very near future! In her final episode on the pod, Crystal, along with co-hosts Robin Greubel and Stacy Wing, reflect on growth, gratitude, and the courage required to embrace terrifying change.
Crystal shares how the podcast stretched her beyond comfort, teaching her that her voice didn't need to be perfect to be powerful. She thanks the community of listeners, guests, and especially her co-hosts for building confidence she never knew she possessed.
It also helps that the ADHD brain that once made her curiosity feel like a burden found a home, and a tribe, on the pod!
The Dames of Detection also talk about doing scary things as a catalyst for growth. Stacy offers an inspirational quote she borrowed: "Confidence doesn't come from preparation, it comes from survival." Which basically means that moving forward before feeling ready is precisely what builds capability!
Crystal also announces her new project: a short-form podcast tentatively titled "What's On Top.”
She thanks Stacy for teaching her about odor behavior and vehicles, and Robin for seeing potential she hadn't recognized in herself. The lily pad metaphor comes to mind, where teachers provide stepping stones that students eventually leap from, not destinations where they remain forever.
Crystal signs off with the reminder that, if something terrifies you while simultaneously tugging at your purpose, that fear signals you're on the right path!

Our hosts, Robin Greubel, Stacy Barnett, and Crystal Wing, break down how time, airflow, and placement reshape detection dog work!
They kick things off by describing a week of hides left up to 96 hours, the longest-out scenario that reveals how odor pools migrate and change. Drawing from this experience, our hosts brainstorm creative ways to design hides that can better help your dog read scents.
Central is the concept of "odor availability", which explains why surface area, sealing, and enclosure control whether a source itself (and not merely source size) ever presents to a dog.
Using a paint-flow metaphor, they explain how multiple sources age and send "tendrils" of scent through a structure, forcing dogs to sort overlapping plumes to find dominant streams.
They stress that short-set hides (minutes) produce different search behaviors than long-set hides (days), and that sport trials, which run many teams, may not reflect operational realities.
Robin, Stacy, and Crystal urge handlers to read odor-pool cues, practice sourcing through mixed plumes, and intentionally vary hide age and intensity so dogs learn robust, transferable detection skills across environments.

“Search and rescue work is the volunteer profession that you pay to do and is one of the most stressful things you can ever do, because somebody else's life could depend on what you're doing.”
In part 2 of their conversation with Steve White, Robin Greubel and Stacy Barnett ask about the development of Hydrated Intensive Tracking (HIT), which evolved from experiments with scent-in-a-bottle methods.
Steve’s breakthrough came at a U.S. Police Canine Association seminar when handlers lacked marker training skills. By hybridizing traditional food-in-footstep methods with spray lines, Steve discovered that dogs crossing pavement with spray present kept their heads lower even after the spray evaporated. It’s classical conditioning at work!
Steve's training philosophy emphasizes creating calm, methodical working dogs rather than frantic high-energy animals. He seeks dogs with "conditioned emotional responses" of focused steadiness. He believes that clearheaded dogs perform better in difficult urban environments. This approach influenced his article training, where teaching dogs to find tiny objects like washers creates precision that makes finding larger targets effortless.
Robin and Stacy zero in on the importance of generalization and stimulus control. Dogs absolutely distinguish training from operations, requiring extensive work in operational environments. Steve advocates for the "Green Eggs and Ham" principle. That is, can your dog perform here, there, everywhere? Handlers often mistake lack of stimulus control for lack of behavior knowledge.
His current work with the United States Police Canine Association's Best Practices Working Group aims to preserve police canine programs by shifting focus toward the irreplaceable value of dogs' olfactory capabilities while promoting cooperation-based control methods over force-dependent approaches.

Two-thirds of The Dames of Detection, Robin Greubel and Stacy Barnett, welcome Steve White, a veteran law enforcement K9 trainer whose 46-year career began in military working dog handling in 1975.
Steve discusses the challenges facing modern police canine programs, particularly how vendor-driven training models often prioritize efficiency over optimization, which creates sessions where handlers log hours without meaningful individual development.
Central to Steve's philosophy is building fluency in component behaviors before chaining them together. He emphasizes the "search-locate-report" sequence as the foundation of detection work, and warns against the common mistake of teaching dogs to retrieve training aids initially. This approach creates problems through the “law of primacy:” dogs default to their earliest learned behaviors under stress, leading to dangerous outcomes like consuming narcotics or explosives.
Steve draws a critical distinction between "search dogs" and "examination dogs." Medical detection dogs must systematically examine each sample rather than hunting for the strongest odor source; a dog that vaults past a Stage 1 cancer sample to alert on Stage 4 creates catastrophic consequences. Similarly, explosive detection work often requires methodical examination of luggage or spaces where missing a threat is unacceptable.
Steve traces his evolution from using sport castoff dogs from Europe to developing selection criteria focused on "self-righting" dogs: calm, confident animals who never seek fights but finish them. He shows us why it’s so important to understand the trade-offs inherent in every training decision!
