For dogs with big behaviors, and families who refuse give up on their dog.
Reactivity. Fear. Anxiety. Aggression. It might feel unfixable—but we’ve helped thousands of dogs overcome exactly that.
Rebuild trust. Bring balance back to your home. Enjoy life with your dog again.
Serving the entire Bay Area and Greater Northern California, we specialize in behavior-focused dog training that goes far beyond basic obedience. Living with a dog exhibiting leash reactivity, aggression, anxiety, or fear-based behaviors can be overwhelming. Walks become stressful (if you can go on walks at all), guests are a source of anxiety, and daily life feels unpredictable.
We’ve helped thousands of dogs and owners rewrite their story—let us help you write yours.
Expertise in Complex Behaviors: Our highly experienced dog behavior trainers specialize in addressing severe behavioral issues, including aggression and anxiety.
Personalized Training Plans: We customize your training to fit your dog’s unique needs and your lifestyle.
Balanced, Relationship-First Methods: Our training emphasizes trust and clear communication.
Real-World Readiness: We prepare your dog for everyday situations, ensuring they can handle real-life challenges confidently.
Our training programs are designed to build real-world reliability at a pace that respects your dog’s individual needs, learning style, and emotional state. We don’t rush transformation—we build it through establishing trust, clarity, communication, and consistency.
You will work one-on-one with an expert trainer in your home. This option is best for the DIY owner who wants to be hands on, and for dogs with mild behavior issues.
Our Board & Train Program is perfect choice for everything from obedience to severe behavior issues. Your dog lives and trains with one of our expert trainers in their home — not a kennel facility full of barking dogs. This immersive, real-world program is ideal for behavior transformation and creates deep, lasting change.
Our most popular option combines our highly successful Board & Train program with more in-home sessions — this is our favorite option. Great for dogs (and humans) who need both direct training and continued at-home coaching.
