    About Your Behaviorist Behind D.O.C. of San Diego

    Calm Leadership. Real Communication. True Behavioral Change.

    I’m Arnaldo Villanueva 'David', a canine behavior specialist dedicated to helping dogs and their families build stable, respectful, and balanced relationships.

    My Philosophy

    Behavior First - Not Obedience


    I don’t teach tricks or commands.

    I teach state of mind, structure, and communication, the real foundations that create lasting behavioral change.


    Dogs don’t need perfection - they need clarity.

    When communication becomes simple and honest, behavior naturally improves.


    Every Dog Is an Individual

    Just like children, every dog has a unique personality, sensitivity, and way of learning. There is no “one method fits all.”  I adapt my approach to the dog in front of me- their history, their instincts, their emotional patterns, and their environment.  This is why real-world experience matters more than certifications.

    Why I Choose Real-World Practice

    Certifications teach theory.

    Real dogs teach truth.


    Dangerous dogs, anxious dogs, dominant dogs, insecure dogs -

    none of them improve through textbooks.


    They improve through energy, structure, exposure, and communication.

    My methods come from hands-on experience with hundreds of real dogs in real environments.



    What Clients Experience

    Most owners who come to me have already tried multiple trainers with no results.


    With proper structure and communication,

    most families see noticeable progress within the first hour -

    and if you don’t, your session is free.



    My Intuitive & Spiritual Approach to Dogs

    I believe dogs are deeply intuitive beings - sensitive to energy, emotion, and the unseen dynamics around them. Many behavioral issues are not just about habits or structure but about the emotional and energetic patterns the dog is responding to.


    When a dog displays fear, reactivity, dominance, or anxiety, it often reflects an imbalance in clarity, leadership, or emotional grounding within the home. Dogs read our energy long before they ever listen to our words.


    My approach blends real-world structure with a deeper understanding of presence and intention. I focus on why a dog behaves the way it does, what energy it is following, and what patterns are influencing its decisions.


    Some dogs carry confusion.

    Some carry fear.

    Some carry dominance.

    Some carry past experiences that still shape their reactions.


    But every dog has the potential for balance when guided through calm, grounded leadership.


    My role is to help both dog and human find clarity - where communication becomes natural, the energy settles, and harmony follows. When we change our energy, we change the dog.

      Virtual Dog Behavior Coaching (Zoom)

      Available anywhere - structured guidance from a behavior specialist, right from your home.


      Dog behavior issues don’t always require an in-person visit. Many challenges begin with communication, clarity, and household dynamics - all of which can be addressed effectively through a virtual session. Our Zoom consultations are designed to give you immediate, practical steps to restore balance and improve your dog’s state of mind.


      During your virtual coaching session, we will:

      ✔ Review your dog’s behavior, triggers, and current routines

      ✔ Identify the root causes behind unwanted behaviors

      ✔ Teach you how to communicate clearly and confidently

      ✔ Provide customized strategies you can apply immediately

      ✔ Support you in creating structure, boundaries, and calm leadership inside the home


      Virtual sessions are ideal for:

      • Anxiety, nervousness, overexcitement

      • Minor aggression or resource issues

      • Puppy development and household behavior

      • Leadership training for owners

      • Multi-dog dynamics

      • Preparing for an in-person session


      If you’re ready to understand your dog on a deeper level and receive real guidance tailored to your home and lifestyle, virtual coaching is a powerful first step.
