Off Leash & Unfiltered

Real conversations about dog training, behavior, relationships, and what it takes to create lasting change.

Off Leash & Unfiltered is the dog training podcast from Kati Peppe, owner and head trainer of Diamond K9 Dog Training in Biddeford, Maine.

Kati takes a practical look at the questions dog owners actually struggle with: reactivity, anxiety, aggression, obedience, boundaries, e-collar training, puppy raising, problem behaviors, and the often-overlooked relationship between a dog and its owner.

There is no single technique that explains every dog or every behavior. The podcast explores the reasoning behind training decisions, why certain approaches work for some dogs and situations but not others, and how clearer communication and consistent expectations can help dogs succeed in the real world.

Whether you’re working through a difficult behavior, raising a new puppy, or simply want a better understanding of how dogs learn, Off Leash & Unfiltered offers practical advice drawn from Kati’s experience training dogs and coaching their owners.
