The Story Behind Cosmic Dog Training
Lafayette's Own Certified Dog Trainer
Cosmic Dog Training started with Koda, a rescue dog whose severe separation anxiety nearly cost him his life. His recovery changed everything. Founder Kathleen Valentine discovered games-based concept training while looking for answers, and never stopped. What started as a solution for Koda became a career, and ongoing education. Games-based training worked for Koda. It has worked for many families since.

Kathleen Valentine
Founder, Head Trainer, Behavior Specialist
“Every dog has potential. My job is to help you uncover it through science, play, and connection.”
Kathleen Valentine is a certified Pro Dog Trainer and Behavior Specialist with advanced credentials from Absolute Dogs. Her career took an unexpected turn when her family adopted Koda, a rescue dog with severe separation anxiety who could not be left alone. After other methods failed, she found games-based concept training. The results were immediate, and the positive reinforcement approach made sense to her on every level. Today Koda can be left at home for any length of time and often prefers his crate.
During her five years of study, she traveled to the UK twice to train directly under Lauren Langman and Dr. Tom Mitchell, the founders of Absolute Dogs and Help! My Dog, and continues to pursue a bachelor’s degree in Canine Behaviour through Canine Behaviour College.
Building on that foundation, Kathleen helps families find joy and confidence with their dogs. She trains alongside her husband Phillip and their four dogs, two rescues and two border collies. Working with her own dogs every day keeps her skills sharp and her empathy real.
When she is not teaching classes or private sessions, she is out hiking Colorado trails or diving into the latest dog behavior research.
Phillip Valentine
Training Assistant & Marketing Lead
Phillip has been a dog person his whole life. Growing up around farms and animals of all kinds gave him an intuitive understanding of animal behavior that translates naturally to dogs. Kathleen would say he has a gift for it.
At Cosmic Dog, he manages the marketing and design side of the business and trains the dogs at home daily using the same games-based methods. He is the proud dad of Koda, Leo, Arrow, and Fabulous.
Koda
The original. Koda’s transformation from a dog who couldn’t be left alone to a confident, settled companion is the reason Cosmic Dog Training exists. These days, he’s happiest on a hiking trail or snuggling on the couch.
Leo
Leo joined the family as a foster and never left. This sweet, sensitive Shiba-Inu/Shar Pei mix came with early fears and insecurities that deepened Kathleen’s passion for training. He and Koda became an inseparable pair. He’s gentle, silly, and happiest sitting in the sun, taking in the world he used to fear.
Arrow
Arrow is a high-energy Border Collie who came to Colorado from Kathleen’s trainers in Devon, UK, a Devon Gem. He’s passionate, focused, and toy-obsessed, and is working toward becoming an agility competitor. He is charming, with frisbee as his first love.
Fabulous (Fabi)
Fabi is a relative to some of the dogs at Absolute Dogs in the UK and the family’s first service dog in training. True to his name, he brings enthusiasm to everything he does. Fast-paced adventures are his favorite, and he is our only dog who is affection motivated.
