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.

OMG! My Dog Hates Doggy Daycare!

Doggy daycare and dog parks carry a high level of risk and a very low level of benefit. What has become obvious to me over the years is that a lot of dogs don’t actually enjoy themselves in these environments but that it just isn’t always obvious. Until it is. And that is often post training because your dog is now used to being in environments where dogs are under control and someone is advocating for them. In this episode

The Place Command For Dummies—Get The Most Out Of Your Dog Training

Does your dog go crazy when people come over? Do they beg when you’re eating? Or maybe they are always getting into stuff or stealing socks out of the hamper or chewing your furniture? These are all reasons why people love using the place command. But experience has taught us that place doesn’t really “fix” these problems on its own. So why do we really love it? And why do we tell people to do it? Who benefits from it?

Is Your Dog Extremely “Sensitive” or “Dramatic”? Here’s What It Means.

Some dogs can be super big babies. Big dogs and small dogs alike can fall into this category.

Dog Obsessions, Addictions, Fixations… Oh My!

In this Off Leash and Unfiltered episode, Kati Peppe—owner of Diamond K9 Dog Training in Biddeford, Maine—tackles dogs who are stuck in obsessive, addictive loops: reactivity like a “drug,” shadow/light chasing, water or ball fixation, and destructive chewing.
