"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.

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.
