Expert Dog Training & Behaviour Transformation in London

Personalised training for your dog. Practical coaching for your family. Lasting Results in everyday life.



We understand

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.


Tailored, Professional Training

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.



Real-World Performance

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.


A Higher Standard Of Service

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

Juan Gonzalez


I’m Juan, co-founder and lead trainer at JCDTK9. Originally from Málaga, Spain, I’ve dedicated my professional life to understanding dogs and helping families build better relationships with them through training.


My work covers puppy development, obedience and behavioural challenges, alongside protection and sport training. In 2026, I earned my Decoy Certification with the Protection Sports Association (PSA), adding to my professional development in canine behaviour and training.


I take a balanced approach, adapting the training to each dog’s temperament, experience and needs. Motivation, clear communication, consistent boundaries and owner education are central to my work.


My goal is to develop both ends of the lead: a dog with stronger skills and a family with the knowledge and confidence to maintain them in everyday life.


Carmen Millan

I’m Carmen, co-founder and CEO of JCDTK9. I oversee the care, organisation and daily routines that support each dog’s training, while helping families feel informed and supported throughout their programme.


Working closely with Juan, I assist in training sessions and help maintain consistency beyond them. Within our balanced approach, I focus on clear communication, structured activity, enrichment and quality rest, adapting daily care to each dog’s individual needs.


I also support the relationship between our team and your family, helping you understand your dog’s progress and prepare for the next stage.


From the first conversation to your dog’s transition home, I want you to understand what we’re doing and feel confident asking questions.



For me, attention to detail means knowing the dog in front of us, recognising what they need and ensuring their care supports the goals we’re working towards together.
