A Higher Standard Of Service

You're not just looking for basic training, you are looking for clarity, control, and a dog you can confidently live with. Whether it's disobedience, reactivity or simply lack of structure, these issues don't stay small. At JCDTK9, we work with owners who expect more, and are ready to achieve it.


-

Every dog we work with is placed on a structure, personalised pathway. From 1 to 1 sessions to immersive Day & Training program while you are in the office, we build training around your lifestyle. No generic plans, just precise, professional work designed to create reliable, lasting behaviour.


-

Control isn't built in quiet environments. It's proven in real world. Our training focuses on reliability under pressure: Busy streets, high distractions, everyday life. The result is a dog that listens, responds, performs when it actually matter and most importantly, live the best life a dog can live.


-

We operate with a full-service mindset. Every client receives ongoing guidance, structure, and accountability throughout their journey. This is a professional process designed to elevate both dog and owner to a higher standard.

ABOUT US


Meet Juan and Carmen — The Heart Behind JCDTK9
We’re Juan and Carmen, proud founders of JCDTK9, and our journey began in a small village in Málaga, Spain. Growing up surrounded by dogs, our love and connection with them have been an integral part of our lives for as long as we can remember. It was this shared passion that brought us together, and eventually inspired us to build a business that helps families and their furry companions thrive.

Juan Gonzalez
As the lead trainer and certified behaviorist, I specialize in unlocking the potential in every dog, no matter the challenge. Since 2022, I’ve dedicated myself to refining techniques, studying under world-renowned experts, and guiding over 250 families in London to success. My approach goes beyond training dogs—it's about empowering owners to become their dog’s best trainer, fostering lifelong bonds through communication and trust.

Carmen Millan
I’m Carmen, CEO and co-founder, and I bring the care and structure every dog needs to feel secure and loved. From personalized boarding and daycare to assisting in training sessions, I ensure every dog under our roof feels at home. I’m constantly growing in this field, working toward certification in dog grooming to offer a full spectrum of services.

Together, we blend our skills and passion to create an environment where dogs flourish, and their owners feel supported every step of the way. When you choose JCDTK9, you’re not just signing up for a service—you’re joining a family that’s dedicated to helping your dog reach their full potential.
