Leash reactivity often develops from frustration, fear, or lack of confidence while on leash. When a dog can’t move freely to greet or avoid other dogs, the tension can trigger barking, lunging, or pulling. Our training focuses on addressing the root cause—helping your dog feel calm, focused, and confident around distractions.
Yes. Often times aggression is rooted in fear, anxiety, or confusion—not dominance. With proper structure, communication, and balanced methods, even severely reactive or aggressive dogs can learn calm, safe behavior. At Koru K9, we’ve helped thousands of dogs overcome aggression with proven, humane training techniques.
Very rarely. Most dogs labeled “untrainable” are simply misunderstood or lack clear guidance. Our trainers are experienced in working with high-drive, anxious, and reactive dogs safely and effectively—even those turned away elsewhere.
Leash reactivity usually looks like barking, pulling, or lunging on walks but doesn’t always mean true aggression. Aggression involves intent to harm and can appear in multiple contexts (territorial, fear-based, or resource guarding). Our trainers assess your dog’s behavior to create a customized plan that addresses both reactivity and aggression safely.
Every dog is different, but most owners see noticeable improvement within the first few sessions. Consistency at home is key. Our programs—private lessons, in-home training, or board and train—are designed for lasting, real-world results, not quick fixes.
Because training success depends on owner participation and follow-through, no ethical trainer can guarantee behavior outcomes. What we guarantee is an expert team, proven methods, and lifelong support to help you and your dog succeed together.
We use balanced, real-world training that combines structure, accountability, and relationship building. Dogs train in realistic settings—not just a sterile facility—so the behaviors they learn transfer directly into everyday life.
Our most popular program. Your dog lives in the loving home of one of our trainers, and is trained in real world environments. No kennels full of dogs here! We keep programs small to ensure your dog gets plenty of training and care.
Hybrid Training Programs
A blend of immersive Board & Train and private sessions, this option is our favorite, and gives you the flexibility of continued at-home learning paired with expert guidance.
Private, In-Home Dog Training
Our expert dog trainers come directly to your home, and work hands-on with you. This training approach is ideal for addressing obedience training, and mild behavior issues.
Puppy Training Programs
Set your puppy up for success with our structured foundation training. We focus on crate training, potty training, confidence building, and early obedience—preventing future issues before they start.
Let’s turn the chaos into calm, and get you enjoying life with your dog again.
