About K9 Trails 4 Tails LLC

Based on what the business publishes about itself

Jeff Yamaoka, the owner of K9 Trails 4 Tails, describes a path into dog training that started with his own struggles. According to his site, after adopting two dogs, one in 2013 and another in 2016, he found himself working through challenges getting them to listen, eventually consulting with trainers and a behaviorist before turning that experience into a career.

The Vallejo-based business offers consultations and in-home training sessions. Their site emphasizes foundational obedience work: leash walking, threshold training at doorways, place and crate training, and recall. Yamaoka's stated philosophy centers on the idea that most dog behavior stems from the owner's actions and energy rather than being fixed traits in the dog. Training, as he describes it, focuses on rebuilding the relationship between owner and dog through what he calls leadership, structure, and affection.

The business appears oriented toward pet owners looking for hands-on guidance in their own homes rather than board-and-train programs. While the site doesn't list formal credentials or certifications, Yamaoka presents his approach as rooted in personal experience, both as a dog owner who faced common frustrations and as someone who has fostered dogs. For owners curious about this training style, a consultation would be the place to start asking questions about methods and fit.
