About us
At Puppy Einstein, we believe learning should be as fun and rewarding for dogs as it is for the humans who love them.
Founded by Derek Calado, CPDT-KA CCBC-KA, Puppy Einstein combines science-based training with real-world experience to deliver results that last. With over a decade of hands-on work in dog behavior, structured playgroups, and client education, our approach is built on clarity, consistency, and communication.
What started as a small playgroup and behavior program in Hudson, MA has grown into a full-scale training and education hub — a place where owners, trainers, and dogs all learn together. Whether you’re raising your first puppy, working through behavioral challenges, or looking to deepen your understanding of dog training, we provide the structure, support, and community to help you succeed.
Our Approach
We combine positive reinforcement, learning theory, and practical application in every session. Our philosophy is simple:
“Train with understanding, not intimidation.”
Each lesson, group class, and online course is built around clear communication, empathy, and evidence-based methods—ensuring lasting results and a confident, connected relationship between you and your dog.
Our Mission
To make high-quality, science-backed dog training accessible, supportive, and empowering for both owners and aspiring professionals.
We’re building a community of educated, compassionate dog owners and trainers who believe that better communication creates better lives, for dogs and people alike.
Meet The Founder
Hi, I’m Derek Calado, CPDT-KA, CBCC-KA, founder of Puppy Einstein.
My journey in the dog world began more than a decade ago as a grooming assistant and dog walker, where I learned the value of patience, observation, and building trust with both dogs and their owners. From there, I spent four years managing a busy dog daycare, gaining hands-on experience with canine behavior, group dynamics, socialization, and the everyday challenges that dog owners face.
In 2014, I took the leap and founded Puppy Einstein, a small training and playgroup program built around structure, consistency, and understanding. What started as a handful of playgroups and private lessons has grown into Puppy Einstein Academy, serving dogs and their families through training, behavior consulting, enrichment, and education.
As a Certified Professional Dog Trainer (CPDT-KA) and Certified Canine Behavior Consultant (CBCC-KA) through the Certification Council for Professional Dog Trainers (CCPDT), I am committed to providing science-based, positive reinforcement training that is both effective and humane. I believe that successful training is about more than teaching behaviors—it’s about helping owners understand their dogs, build stronger relationships, and create lasting change.
Whether I’m working with a new puppy, a dog struggling with behavioral challenges, or mentoring the next generation of trainers, my goal remains the same: to help dogs and people communicate more clearly and live better lives together.
