Journey to Becoming a Leader in the Dog Training Industry
Cartrell Cooper’s journey into leadership was never about chasing a title—it was about following a calling to become the most knowledgeable dog trainer he could be. From a young age, he shared a natural bond with animals, particularly dogs, and recognized his unique ability to understand their needs and behaviors. His early work as a veterinary assistant at Brooklyn Pet Hospital gave him structured exposure to animal care, while his time in the Air Force sharpened his sense of discipline, leadership, and responsibility. Working alongside mentors such as Richard Walter and Loroli Deleny further refined his purpose in training. His parents, Dr. Lucille Cooper and Dr. Cartrell Cooper Sr., instilled in him the principle that true leadership means setting the example when others hesitate.
A pivotal moment in his career came when he transitioned from training service dogs to working directly with families. Through this shift, he discovered that while dogs required training, people often needed coaching as well. Many families struggled not because their dogs were “bad,” but because they lacked the tools, patience, and mentorship to communicate effectively. The founding of Big D’s Dog Training became another turning point, driven by his mission to bring honesty, structure, and a philosophy rooted in direction reinforcement—rather than gimmick-based approaches—into an industry often cluttered with shortcuts. Over decades, Cartrell’s leadership evolved step by step through community service, the creation of organizations like the National Dog Trainers Association and Action Dog Association, the authorship of educational books, and the mentorship of new trainers. Each decision reinforced his belief that leadership in dog training requires persistence, authenticity, and a steadfast commitment to principles that truly serve both dogs and families.
Inspiration Behind Founding Big D’s Dog Training
The inspiration for Big D’s Dog Training arose from a blend of personal passion and frustration. Cartrell witnessed countless dogs being surrendered to shelters simply because families lacked proper training knowledge. He also observed a troubling trend in the industry—trainers offering one-size-fits-all programs or relying on treats, gadgets, and punishment rather than teaching genuine communication. Determined to address this, Cartrell envisioned a training model mirroring the way a mother dog teaches her litter: through clear direction, consistent reinforcement, and patience. This philosophy, known as direction reinforcement training, became the backbone of Big D’s—an approach that is humane, effective, and enduring.
Beyond the practical aspects of training, education became a central inspiration. Through books such as Pawsitively Pawsome: The Ultimate Dog Lover’s Textbook and It’s Never Done That Before, Cartrell extended his teachings beyond the walls of his facility. Big D’s became more than a business—it evolved into a movement dedicated to raising the standard of understanding between humans and their canine companions.
Core Values and Principles That Guide Leadership
Integrity, education, and resilience have been the cornerstones of Cartrell Cooper’s leadership journey. Integrity means never compromising on honesty, even when it might cost business. Families entrust him with their beloved pets, and that trust demands complete transparency. Education reflects his belief that true leadership extends beyond training—it is about teaching and leaving others better informed, whether through mentoring, seminars, or writing. Resilience has been essential, as leadership often involves setbacks, unpredictable outcomes, and criticism. For Cartrell, the measure of a leader lies in the ability to adapt, persevere, and stay true to the mission despite obstacles.
Influences That Shaped Leadership Style and Vision
Cartrell’s greatest influence has been his mother, Dr. Lucille Cooper, who instilled resilience and a refusal to quit in the face of rejection. Her lessons in coping and perseverance shaped his approach to guiding both people and dogs. Professional mentors in veterinary medicine and experienced trainers from his Air Force service and early career further honed his skills. Equally impactful were negative examples—trainers who cut corners or treated clients poorly—teaching him what kind of leader he did not want to become. From these experiences, Cartrell learned that leadership is not only about doing things right but also about refusing to do things wrong, even when shortcuts appear tempting.
Disrupting the Dog Training Industry in 2025
In 2025, Cartrell Cooper and Big D’s Dog Training are disrupting the industry by rejecting gimmicks and returning to the fundamentals of effective communication and consistent reinforcement. At a time when social media trends and reward-only models dominate, Cartrell emphasizes discipline, structure, and meaningful engagement between humans and dogs. Through the Action Dog Association, he also introduced a groundbreaking concept—scent-based competitions where dogs search for everyday items like keys or phones. This innovation has brought the excitement of working-dog training to families, blending utility with fun. By publishing guidebooks, certifying judges, and organizing events, Cartrell has created a new lane for dog sports, enriching the lives of both dogs and their owners.
Staying Ahead of Market Trends and Innovating Continuously
Cartrell stays ahead of market trends by maintaining close contact with families and dogs in real-world settings. Direct experience allows him to identify emerging needs, from puppy training challenges to advanced behavioral techniques. He continually studies new research in animal behavior, attends industry events, and listens to insights from both experts and clients. Rather than chasing every fad, he carefully filters what truly adds value. For instance, he embraces technology like GPS-based collars for enhanced safety while rejecting tools that bypass the essential relationship between human and dog. Writing also keeps him innovative, as each publication compels him to refine and reassess his methods to ensure they remain both relevant and timeless.
Overcoming Challenges in 2025
The most significant challenge of 2025 was managing rapid business growth while maintaining the personalized quality that defines Big D’s Dog Training. As demand surged due to popular books and Action Dog Association events, Cartrell risked overextension. He met this challenge by expanding mentorship and certification programs through the National Dog Trainers Association, enabling him to train others who uphold his values and approach. By investing in people, he ensured that the company scaled responsibly without compromising its integrity or mission.
Approach to Risk Management and Decision-Making
For Cartrell Cooper, risk management is rooted in preparation and honesty. He evaluates every decision through two guiding questions: Does this align with his core values and mission? Will this serve the long-term well-being of dogs and families? While open to taking calculated risks, he avoids reckless ventures. Launching the Action Dog Association was one such calculated risk—an untested idea that ultimately succeeded because it aligned perfectly with his mission of strengthening human-canine bonds through meaningful activities.
Defining Qualities of a Great Business Leader
Cartrell believes that the modern business leader must be authentic, adaptable, visionary, and committed to teaching. Authenticity fosters trust, adaptability ensures resilience amid change, vision inspires progress, and a teacher’s mindset empowers others to grow. He strives to embody these qualities by staying true to his principles, embracing innovation, sharing knowledge through writing and mentoring, and leading by example in every aspect of his work.
Inspiring and Motivating the Team
Motivation at Big D’s Dog Training stems from purpose. Cartrell reminds his team of the deeper “why”—the joy of transforming a once-unruly dog into a calm, confident companion, and the relief families feel when they realize they can keep their beloved pets. He frequently shares success stories to reinforce the mission and leads by example, stepping in wherever needed to show his commitment. This hands-on approach inspires his team to match his dedication and passion.

Having personally experienced exclusion, Cartrell ensures that training programs are accessible to all, regardless of background or financial means. Scholarships, mentorships, and flexible options allow anyone to benefit from quality training. Within his team, he cultivates an environment where every voice matters, fostering trust and a sense of belonging among staff and clients alike.
Balancing Business Goals with a Positive Work Environment
For Cartrell, balance begins with clear communication and realistic goal-setting. By establishing achievable objectives and celebrating milestones, he reduces pressure and builds morale. At Big D’s, progress is valued over perfection, and joy is central to the work culture. Laughter, shared successes, and the daily rewards of working with dogs create a positive environment that fuels motivation and long-term commitment.

Over the next five years, Cartrell envisions Big D’s Dog Training continuing to raise the standard for humane and effective training practices. Through publications, certification programs, and innovative events, he aims to lead the industry back to fundamentals—structure, direction, and authentic connection. His goal is also to bridge the gap between professional trainers and everyday families, making expert knowledge widely accessible and ensuring more people experience the rewards of a well-trained dog.
Advice for Aspiring Business Leaders
Cartrell’s advice to future leaders is clear: Know your purpose, resist fleeting trends, invest in education, and remain resilient. Understanding one’s “why” provides the foundation to weather challenges. Building a lasting enterprise requires focus and integrity, not popularity. Leadership is not about being liked—it is about being trusted. He encourages entrepreneurs to build trust through honesty, consistency, and dedication to their mission.
