What pet owners are saying.

“

Cadman did an incredible job with our Maltipoo, Mochi. Before working with him, she could get anxious in unfamiliar situations and around new people or dogs. Through his calm, thoughtful approach, he helped her build confidence instead of just teaching obedience. She’s much more relaxed meeting new people, far better socialized with other dogs, and noticeably more confident in new situations. The training has made everyday life — from walks to cafes to traveling — so much easier and more enjoyable for all of us.

Cadman was exactly what Marley and I needed. From our first session, it was clear that he is incredibly knowledgeable and genuinely passionate about the dogs he works with. Marley enjoyed every session, and I learned just as much as he did. One of the biggest lessons for me was realizing that I needed to be more patient and consistent. I’m grateful for Cadman’s guidance — he truly cares about both the dogs and the people behind the leash.

Cadman is a standup guy and awesome with dogs. He helped my injured and reactive dog when he tore his ACL. I couldn’t have managed without his care and help.
