All J9’s K9s Trainers continue their education by regularly attending dog training and behavior seminars. They are certified by the Certification Council for Professional Dog Trainers ®, the leading independent certifying organization for the dog training profession. This means they have passed a rigorous exam to demonstrate mastery of humane, science-based dog training practices and must pursue ongoing education to stay current in the profession in order to maintain their certifications. You and your dog deserve a trainer you can trust!
