Dion R. Studinski

Dion R. Studinski is a professional dog trainer, behaviorist, and aggression specialist based in Denver. As the owner and founder of Ancillary K9 Dog Training, Studinski has worked with dogs and their owners, earning recognition as one of Denver's top dog trainers. A University of North Dakota graduate, he holds certifications in dog behavior and training, is a USCA Protection Helper Classified, an AKC Evaluator, and a member of the International Association of Professional Dog Trainers.

Studinski's entry into professional dog training began with a personal challenge involving a reactive dog. After unsuccessful attempts to find a suitable trainer, he turned to working and protection dog training, finding mentorship in Schutzhund, which emphasizes precision training, drive development, and behavioral shaping. This experience shaped his methodology, combining real-world working dog techniques with practical approaches tailored to family dogs.

At Ancillary K9, Studinski specializes in obedience, aggression, and behavioral issues, simplifying complex behaviors into actionable training for owners. He employs canine psychology and science-based methods to address issues efficiently. Known as a balanced dog trainer, Studinski integrates both rewards and consequences to help dogs and owners achieve effective outcomes. He maintains that there are no problem dogs, only those who have not received proper training. This philosophy drives him to take on challenging cases, often helping dogs at risk of being rehomed, surrendered, or euthanized.

Studinski advocates for a nuanced approach to canine behavior, moving beyond mainstream all-positive training methods, which may not address serious behavioral issues such as aggression or anxiety. He emphasizes the importance of clear boundaries, structure, and a balanced approach for reactive dogs. Through persistence and a system rooted in working dog principles, Ancillary K9 has become a trusted dog training practice in Denver.

In addition to hands-on training, Studinski is a keynote speaker and industry expert, addressing topics in animals and wildlife, business, and motivational subjects. He has spoken on subjects such as "Understanding and Mitigating Aggression in Dogs," sharing his expertise with broader audiences. Studinski has been featured in media, including interviews discussing his training methods, program history, and perspectives on animal obedience, behavior, and protection. His career is defined by measurable results and a commitment to lasting change, making him a leading voice in canine behavioral science and a resource for dog owners facing complex challenges.
