“That’s Not a Marker”: Cleaning Up Your Communication

“What am I doing that’s setting my dog up where I feel like I need to reward for effort?” Our hosts, Robin Greubel and Stacy Barnett, explore what it means to “ask your dog a question” in training. Rather than guessing why a dog is struggling or rushing to a fix, they recommend deliberately testing one criterion at a time to find out what the dog understands and where the breakdown is. Stacy shares how simplifying the setup revealed that Jack needed to see a container to recognize the source, while Robin describes how Raven’s high hunt drive made it difficult to shift into her trained final response. The Dames of Detection also discuss the risks of rewarding vague “effort” or incidental behaviors, which can create confusion and reinforce habits handlers didn’t intend. They encourage trainers to reinforce specific, meaningful behavior, build criteria thoughtfully, and decide whether a training issue matters operationally before choosing to address it.  Their takeaway: make assessments purposeful, build strong foundations, and choose your battles based on the dog and the work. They also share a few updates: schedules for upcoming intentional handling, hide-setting, and distraction camps are expected after the first of the year, with sessions anticipated in May and June. Robin mentions possible European training opportunities in April or May, and the hosts discuss small-group training options at Robin’s farm. Key Topics:Defining “Asking Your Dog a Question” (01:59)Troubleshooting by Eliminating Criteria: Jack’s Container-Visibility Challenge (06:58)Raven’s Hunt Drive, Arousal, and Final Response (11:46)Choosing Training Priorities Based on Operational Needs (18:34)The Risks of Rewarding Effort and Reinforcing Unintended Behaviors (27:41)Building Training Criteria as a Foundation, Not a Ladder (34:34)Upcoming Training Programs and Events (47:41) Resources:Fenzi Dog Sports Academy – Schedule and Syllabus: https://www.fenzidogsportsacademy.com/schedule-and-syllabusK9 Sensus – Working K9 Academy: https://k9sensusacademy.thinkific.com/“Book a Weekend with Us!”: https://www.k9detectioncollaborative.com/coaWe want to hear from you:Check out the K9 Detection Collaborative FB page and comment on the episode post!K9Sensus Detection Dog Trainer AcademyK9Sensus Foundation can be found on Facebook and Instagram.

“There are 100 ways to train a dog. And you’ve got to train the dog that’s in front of you.” Our hosts, Robin Grubel and Stacy Barnett, unpack the role of markers in scent-detection training—and why a clicker or verbal “yes” isn’t a magic button. They explain the difference between a marker that signals the end of a behavior and a cue that asks the dog to do something. They also discuss how a click can accidentally become a cue for a trained final response if it’s used the same way every time and never faded. Robin and Stacy talk about how to make verbal markers clearer and more consistent, when a clicker or whistle may offer better timing, and how reinforcement placement can shape a dog’s independence at odor. They explore the risks of hovering at the hide or pairing odor with food for too long, as well as how location-specific reinforcement cues—such as “eat” or “catch”—can help handlers communicate how a reward will be delivered. Their central message: choose your training tools with a clear objective in mind, and adapt your approach to the dog and the skill you’re building. Whether you’re developing a trained final response, working on close-proximity hides, or building search skills, thoughtful marker use can give you more options and cleaner communication.  Key Topics:Markers versus Cues (03:30)What Makes a Verbal Marker Clear and Consistent (04:43)Timing Challenges with Verbal Markers (07:12)When to Use a Clicker—and When It May Not Be Needed (10:05)Pairing Odor with Food and Why to Fade It (12:13)Using Markers to Encourage Handler Distance and Dog Independence (19:28)Why Whistles Can Help with Loud Bark Alerts (22:09)Choosing Reinforcement Placement for the Training Goal (24:31)Location-Specific Reinforcement Cues and Arousal (29:42)How a Clicker Can Accidentally Become a Cue for the Trained Final Response (33:58)Distance, Duration, and the Six Ds (38:38) Resources:Fenzi Dog Sports Academy – Schedule and Syllabus: https://www.fenzidogsportsacademy.com/schedule-and-syllabusK9 Sensus – Working K9 Academy: k9sensusacademy.thinkific.com“Book a Weekend with Us!”: https://www.k9detectioncollaborative.com/coaWe want to hear from you:Check out the K9 Detection Collaborative FB page and comment on the episode post!K9Sensus Detection Dog Trainer AcademyK9Sensus Foundation can be found on Facebook and Instagram.

“Ultimately, it is an art. There is an artistic side to dog training.”Our hosts, Robin Greubel and Stacy Barnett, are back with Paul Bunker of Chiron K9 to discuss the finer points of calibration and communication between dog and handler!Paul revisits breed temperament. As a few quick examples, pointers and chocolate Labradors are "pedantic," holding out for their exact target odor, while spaniels and Malinois generalize liberally and are more prone to false alerts.That liberal drift is exactly why he built his "three-legged stool of imprinting," rotating training aids early so a dog learns the category of an odor rather than one narrow sample. This is a lesson he first learned when landmine dogs, flawless on Yugoslav TNT, drew a blank on American TNT.During four months of oil spill response in Canada that produced roughly ten thousand confirmed finds, Paul learned dogs can be calibrated to a set concentration, spontaneously ignoring amounts tenfold above or below it.The catch is that concentration itself changes an odor's character, the way a perfume smells floral diluted and fecal concentrated. This means sloppy contamination protocols can inadvertently teach a dog to ignore the very odor it's meant to find.Paul untangles three distinct, often confused protocols: the All Clear, used on discrete objects like luggage, where the dog isn't declaring an area clear, only reporting it found nothing; the Go/No Go, a research tool for presenting a specimen and asking whether it matches; and Blanks, unmarked areas searched with no feedback at all, standard in real operational work. Even directional obedience, he notes, functions as a blank from day one. Key Topics:The Three-Legged Stool of Imprinting (03:42)Calibrating Thresholds After the Canada Oil Spill (08:45)Same Odor, Different Smell: How Concentration Changes Everything (15:55)All Clear, Go/No Go, and Blanks (17:45)Dealing with Lower-Drive Dogs (28:21)Continually Shaping Your Dog’s Brain for Progress (29:14)Directional Training as the Hidden Foundation for Blanks (39:22)Letting Dogs Resolve Their Own Decisions (47:16)Handling Like an Advanced Driver, and a Call for Cohesion (49:06) Resources:Chiron K9: https://chiron-k9.com/The Detection Dog Lab Skool: https://www.skool.com/the-detection-dog-lab-7184/aboutThe Detection of Buried Targets by Canines (book): https://books.by/chiron-k9s-bookstore/the-detection-of-buried-targPublications: https://chiron-k9.com/publications/Texas Tech Canine Olfaction Lab: https://www.depts.ttu.edu/afs/people/nathan-hall/CanineOlfactionLab/index.phpJoint Symposium for Working K9s: https://www.jswk9.com/ We want to hear from you:Check out the K9 Detection Collaborative FB page and comment on the episode post!K9Sensus Detection Dog Trainer AcademyK9Sensus Foundation can be found on Facebook and Instagram.

“Don't trust your dog. Trust your training.”Our hosts, Robin Greubel and Stacy Barnett, sit down with Paul Bunker of Chiron K9. His path from an English farm to British military explosives work eventually led him into conservation detection projects around the globe.Deemed too short for the London police, Paul joined the British military in 1982 and was later tasked, after a fatal minefield accident, with training dogs to clear a safe path to stranded casualties.It was thanks to that project that he coined the “donut effect”, where buried mines leak odor sideways through rainwater rather than straight up. This means dogs must be taught to fringe-sit at the edge of that ring rather than push toward the source.Decades later, that same science shaped his work locating buried Anegada rock iguana nests. Reconnaissance showed the eggs sit in a chamber up to a meter underground, meaning the dog could never be trained on the eggs themselves. Instead, they can learn to detect the filtered headspace odor that actually reaches the surface, built using island sand that Paul smuggled home in Ziploc bags (which nearly got him detained at customs!).Paul illustrates the physics behind the donut effect. Using the example of a coffee filter, he shows that crude oil, once diluted into water, still smells like oil even though it looks crystal clear.That principle underlies nearly everything he trains for, from truffles to human remains, and demands dogs that hunt with intense, ground-level sniffing rather than casual air-scenting.Trusting a dog, Paul argues, starts with trusting the training built behind it. Key Topics:From English Farm Boy to British Army Dog Handler (02:55)A Fatal Minefield Accident and the Birth of a Rescue-Dog Program (11:14)The "Donut Effect": How Buried Mines Leak Odor (15:08)Beyond Landmines: Truffles, Oil, Tobacco, and Water Leaks (22:09)Training Pena for Anegada's Iguana Nests (23:56)The Coffee-Filter Trick: Understanding Diluted Molecules (38:19)Ground Sniffing vs. Air Scenting for Historical Remains (44:31)Liberal vs. Conservative Dogs and Clicker Training (51:12) Resources:Chiron K9: https://chiron-k9.com/The Detection Dog Lab Skool: https://www.skool.com/the-detection-dog-lab-7184/aboutThe Detection of Buried Targets by Canines (book): https://books.by/chiron-k9s-bookstore/the-detection-of-buried-targPublications: https://chiron-k9.com/publications/Texas Tech Canine Olfaction Lab: https://www.depts.ttu.edu/afs/people/nathan-hall/CanineOlfactionLab/index.phpJoint Symposium for Working K9s: https://www.jswk9.com/ We want to hear from you:Check out the K9 Detection Collaborative FB page and comment on the episode post!K9Sensus Detection Dog Trainer AcademyK9Sensus Foundation can be found on Facebook and Instagram.

What to listen for:"The future of leak detection isn't one technology replacing another. It's collaborating with this whole process and working together to save our water."In this second half of their conversation, our hosts, Robin Greubel and Stacy Barnett, talk with Lolita Shaffer to move past the why of water leak detection dogs and into the how.A Cherokee Nation–funded study sent two golden retrievers across 30 miles of pipe in five days, flagging areas where acoustic crews later confirmed a leak 100% of the time, totaling roughly 4 million gallons lost. A dog "hitting" an odor pool isn't a pin on a map. Rather, it's a dome of scent that has to be read, triangulated, and cross-checked. This is the same skill Robin brings from human-remains work, where handlers report behavior, not conclusions.That craft of analyzing that dome of scent, Lolita insists, has to be built and licensed like any trade.Handlers calibrate dogs to a district's specific chemical signature, as chlorine and fluorine sit close enough on the periodic table to complicate a reading. They drill leash discipline, since losing a leash near traffic means losing a thousand-pound risk. And they finish an Operational Readiness Training Evaluation, which is a week embedded with water operators, capped by a double-blind test over a live leak field.There are some pretty big stakes to justify this rigor. Digging up a suspected leak can run $3,000 an hour, so a utility needs confidence and not just “educated guesses”.With up to half the water workforce retiring within five years, and dogs now being asked about lead-pipe detection, it’s clearly a crucial, credentialed profession. It’s one that turns a good nose and a good handler into a real, benefits-earning career.  Key Topics:Dogs and Acoustics in Tandem (01:14)Reading the "Odor Dome" (09:53)A Retiring Workforce and a New Career Pipeline (21:30)Calibrating the Nose to Chlorine (and Fluorine) (24:48)Leash Handling as a Safety Requirement (26:49)The ORTE: A Week-Long, Double-Blind Field Test (29:08)The $3,000-an-Hour Dig (32:01)Not Every Job Needs a Ferrari: Matching Dog to Deployment (32:54)Key Takeaways (39:43)  Resources:K9 Pipeline Detection Association (K9PDA) https://www.k9pda.org/K9 Water Leak Detection University (K9WLDU) https://www.k9waterleakdetectionuniversity.com/Water Leak Detection Dogs on FB https://www.facebook.com/profile.php?id=61551098070706Water Professionals International https://gowpi.org/American Water Works Association (AWWA) https://www.awwa.orgWe want to hear from you:Check out the K9 Detection Collaborative FB page and comment on the episode post!K9Sensus Detection Dog Trainer AcademyK9Sensus Foundation can be found on Facebook and Instagram.

What to listen for:“The certification isn't about proving that the dog can find a leak. It's about giving utilities confidence that the professional team can perform consistently, safely, ethically, and competently.”Lolita Shaffer joins our hosts, Robin Greubel and Stacy Barnett, in this two-part conversation to talk all things water leak detection!It’s a growing niche in the dog training world, but a pretty important one. After all, America's water utilities maintain 2.2 million miles of drinking-water pipe, enough to circle the globe 88 times, and industry estimates put coming rate hikes sharply higher as aging, "non-revenue" leaks go unfound.Acoustic listening equipment, the current industry standard, can hear a hissing pipe but also every earthworm, bug, and passing car, leaving handlers to triangulate blind. Dogs, calibrated on-site to a utility's own water before every job, can generalize across leaks ranging from a quarter-gallon a minute to tens of thousands, including one Florida job under an interstate that was gushing 70,000 gallons a minute.Lolita traces her own path into the work back to hunting-dog trials and a sister already doing human remains detection. It’s a lineage that Robin, coming from cadaver-dog work herself, recognizes immediately in how hydrology carries odor whether the "victim" is a body or a busted water main.Lolita has worked with Water Professionals International to build credentialing that treats handler-and-dog teams the way plumbers or engineers are licensed, and is portable across state lines. She has a five-year goal of turning "detection dog" into a real, benefits-earning career. Stay tuned for the next episode of K9 Detection Collaborative, which will be part two of the conversation!  Key Topics:What Are the Dogs Actually Smelling?

What to listen for:“You can still support your dog, but you do not have to step in and solve [the problem].”Our hosts, Robin Greubel and Stacy Barnett, sit down with returning guest Bob Deeds to unpack a week of Intentional Handling and Hide Setting, the detection camp the two hosts built years ago and this year expanded to fifteen students running six searches a day!Held on Robin's working farm, the course throws teams (Papillons alongside Malinois, cadaver handlers alongside sport dog people) into barns full of donkey dung, hay fields, and wind that Bob, fresh from Texas, learns shifts hourly in Iowa.Hides "misbehave": they migrate, vanish with the moving sun, or disappear when a tractor pulls away from a scent pool.Rather than solving the problem for their dogs, handlers are coached to read arousal. The dog owns exactly one job, the trained behavior; the handler owns everything else.By week's end, students are setting their own hides, and handling that once looked frantic becomes nearly invisible. That’s proof, Bob argues, that intentional handling builds teamwork rather than dependence.Homework matters as much as class time, too. Students now film their runs and coaching, and by day four they're self-correcting before anyone says a word. There’s been so much success this year that Robin, Stacy, and Bob are already looking toward next year's version of the course! Key Topics:A Bigger, Reimagined Intentional Handling and Hide Setting Week (01:39)Building Systematic Toughness (04:56)When Hides Misbehave: Wind, Sun, and a Living Working Farm (10:50)Trainer Ethics and Why Students Should Design Their Own Hides (18:49)The Bowling Alley Analogy and a Live Lesson in Canine Stress Signals (25:23)The Wagon Wheel, Heads-Up Display, and Handler Challenges (30:50)The Donut of Effectiveness and Cyclical "Spinning Plates" Training (40:34)Key Takeaways (44:02)We want to hear from you:Check out the K9 Detection Collaborative FB page and comment on the episode post!K9Sensus Detection Dog Trainer AcademyK9Sensus Foundation can be found on Facebook and Instagram.

What to listen for:“Barking should be under stimulus control. It only happens when I cue it – or when the dog finds target odor – and nothing else.” Our hosts, Robin Greubel and Stacy Barnett, unpack the reality behind bark alerts in detection work. They challenge the idea that a barking dog is always impressive or useful, and ask the critical question: can we train a bark alert versus should we? Drawing on real-world deployment experience, they explain when bark alerts are truly required (such as FEMA USAR) and when they can create unnecessary risks, public misinterpretation, and extra maintenance for both dog and handler. They break down bark alerts as complex behavior chains involving position at source, duration, distance, and continuous barking, and show how easily “criteria creep” leads to dogs leaving odor, orienting to the handler, or only offering a token bark. Using the “dog’s wallet” behavior-economics metaphor, they connect heat, terrain, fatigue, and stress to whether the dog has enough “budget” left to bark at all. The discussion also covers demand versus arousal barking, why barking must stay under tight stimulus control, and why for many teams, a solid stationary response may be a smarter, more sustainable choice than chasing a bark alert that is often easy to improperly train and hard to properly maintain. Key Topics:•       Why a Barking Dog Isn’t Always Sexy (00:00)•       Bark Alert as a Complex Behavior of Duration and Distance (02:31)•       Can We Versus Should We When Choosing a Bark Alert (10:23)•       When Bark Alerts Are Required Versus When They Are Not (11:19)•       Placement of Reinforcement and The Mouse Hole Barrel Setup (14:02)•       Criteria Creep and Dogs Leaving Source or Orienting to Handler (18:36)•       Behavior Economics and The Five Dollar Dog Wallet Metaphor (31:03)•       Demand Barking, Arousal Barking, and Stimulus Control of Barking (25:30)•       Real World Limits: Heat, Fatigue, Terrain, and When Dogs Have No Gas Left to Bark (36:25)•       Why Bark Alerts Are Easy to Train Badly And Hard to Maintain Well (34:30) Resources:•       Link to training an Area Search Dog, which includes the module on a bark alert (and has a worksheet!) https://k9sensusacademy.thinkific.com/products/courses/areasearchdogWe want to hear from you:Check out the K9 Detection Collaborative FB page and comment on the episode post!K9Sensus Detection Dog Trainer AcademyK9Sensus Foundation can be found on Facebook and Instagram.

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. Key Topics:When the Dog Is Right and the Handler Is Wrong (01:36)The Pug That Beat the German Shepherd (12:54)What Skull Shape Actually Tells Us About Scent Work (14:02)A Navy-Funded Micro-CT Scan of 125 Dog Skulls (15:37)The Bloodhound Ear Story No One Has Tested (23:08)Science-Based vs. Evidence-Based: Why the Difference Matters (30:01)The Essential Oil Claim That Doesn't Hold Up to Physics (36:50)Can Nose Work Dogs Learn to Sniff Bigger?

What to listen for:“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.
