Our philosophy

Let the 'heeling' begin.

Ever wonder why some Boulder dog Board & Train programs promise quick fixes or take a one-size-fits-all approach, only to leave you with unreliable results and behaviors that come back? That doesn’t mean your dog is broken — it means they need a different approach.

At Koru K9 Dog Training in the Boulder Bay Area, our Board & Train programs are built for real-life success — not shortcuts. We focus on lasting behavior change through connection, consistency, and clear communication.

Real-life training in real environments. Each day includes structured sessions, field trips, and exposure to everyday distractions — city sidewalks, parks, and real streets, never a kennel run.

“I went online to find a dog trainer for owners with aggressive dogs and came across Koru K9 and Will Greenway. I have had five sessions and a onboarding session all one hour each in Portland, Oregon.”

Questions

Boulder dog training FAQs

Yes, Koru K9 provides professional dog training and behavior modification services throughout Boulder, Colorado, and surrounding areas. Their Boulder offerings include private, in-home training sessions and immersive board-and-train programs tailored to each dog's specific behavioral needs.
Koru K9 serves the entire Boulder, CO area primarily through private in-home dog training and local board-and-train programs. Rather than forcing owners to bring reactive dogs to a facility, trainers work directly in the dog's everyday environment or host them for intensive training.
Koru K9 pricing varies based on whether you choose private in-home lessons or a board-and-train program. Because training packages are customized to each dog's behavioral needs, exact costs are provided after a free phone consultation.
Koru K9’s Boulder board and train program is an immersive dog boot camp where your dog lives in a trainer’s home for 3 to 6 weeks. Unlike kennel environments, dogs receive 24/7 personalized care and real-world distraction training to fix severe behavior issues.
Koru K9 offers three distinct board and train durations in Boulder, CO, depending on the severity of the behavioral needs: a 3-week program for mild issues, a 4-week program for moderate to severe behavior rehabilitation, and a 6-week program for serious aggression or anxiety cases.

Each trainer works with just 1–5 client dogs at a time, ensuring your dog receives focused attention, personalized dog training, and plenty of affection in a real home environment. This small, intimate setting allows our expert trainers to tailor each session to your dog's unique personality and behavior challenges—whether it's leash reactivity, separation anxiety, or basic obedience. Your dog isn't just trained—they're cared for like family.

Your dog will receive exceptional care, personalized training, and plenty of individual attention throughout their stay. In our Board & Train program, each trainer works with only 1 to 5 dogs at a time. This intentionally small size ensures your dog receives the focused support they need to succeed. Each day includes multiple one-on-one training sessions, play, physical exercise, and rest. Your dog will live in the trainer's home—not a kennel—and will be treated like one of their own. We don't just teach commands, we help your dog build confidence, trust, and the skills they need to thrive at home and in the real world.

Your dog's safety is our top priority at Koru K9. During our Board & Train program, your dog lives in a safe, structured, and supervised home environment—not a kennel facility. This allows for 24/7 monitoring, individualized care, and secure containment when dogs are not actively training or supervised. Each dog is housed in a crate when unattended, which not only ensures safety but also supports structure and calm behavior. Our trainers follow strict safety protocols to prevent injury, stress, or accidents. From controlled environments to professional handling, our training programs are designed to keep your dog safe, secure, and thriving throughout their stay.

Yes — your dog will absolutely remember you after completing their Board & Train program. Dogs are deeply bonded to their people, and that connection doesn't disappear during training. In fact, time spent apart often strengthens the bond. Rest assured you will be greeted with tails wagging, full-body wiggles, and all. Throughout the program, your dog is learning new skills, gaining confidence, and practicing calm behavior. When you reunite, you'll see not only a dog that remembers you, but one that is the best version of themselves. Our go-home lesson helps you step into your new role as the leader your dog needs, and we provide clear, personalized guidance to make the transition smooth and successful. With continued consistency at home, you'll build an even stronger relationship with your dog.
