Ryan Duggins is the founder and head trainer of Dugie's Diamond Dog Training, serving Naperville, IL and the surrounding western suburbs. His passion for working with dogs started at a young age, and over the years he's developed a training approach that addresses the biggest failure point in the dog training industry: the gap between what a trainer teaches and what an owner can maintain.
Ryan's unique hybrid approach combines day training with in-home owner education, ensuring that every dog gets professional-level training AND every owner learns the skills to maintain it. Your dog comes to Ryan for three focused hours of training, then Ryan visits your home to transfer those skills to you and your family. This dual approach produces faster results and better long-term outcomes than any traditional training format.
Unlike board-and-train programs that separate your dog from their home for weeks, Ryan's day training model keeps your dog in their familiar environment every night. No kennel stress, no separation anxiety from extended stays — just intensive professional training during the day and comfortable evenings at home. It's the best of both worlds.

Ryan believes that training a dog without training the owner is a recipe for failure. That's why owner education is built into every single session — not as an afterthought, but as a core component of the program. By the end of your training, you'll have the knowledge, skills, and confidence to maintain your dog's training independently for the rest of their life.
Every training plan is customized to the individual dog and family. Ryan evaluates your dog's temperament, your household dynamics, and your specific goals to create a program that addresses your reality — not a cookie-cutter curriculum designed for a generic dog. From puppy foundations to advanced behavior modification for aggression and reactivity, Ryan's programs deliver real, measurable results.
Serving Naperville, Joliet, Plainfield, Shorewood, Channahon, Oswego, Yorkville, Minooka, Morris, Aurora, Bolingbrook, and Romeoville, Dugie's Diamond Dog Training brings the diamond standard of professional dog training to your doorstep.

Ryan completely transformed our German Shepherd's behavior. We did the day training program and I was blown away — after just a few sessions, our dog was walking on a loose leash and responding to commands reliably. The in-home lesson at the end of each session was a game-changer for us as owners. Highly recommend to anyone in Naperville!
We tried two other trainers before finding Ryan and wish we'd started here. Our reactive pit bull mix was lunging at every dog on walks. Ryan's approach was patient, methodical, and most importantly — effective. Within weeks, we could walk past other dogs without incident.
Our 4-month-old Golden Retriever was biting everything in sight and having accidents all over the house. Ryan's puppy training program addressed both issues systematically. Best investment we've made for our family!
I was skeptical about the day training concept at first, but Ryan proved me wrong. My Husky was out of control — pulling on leash, ignoring commands, jumping on guests. After the program, it's like we have a completely different dog.
Ryan helped our anxious rescue dog with separation anxiety. She used to destroy the house every time we left. Now she calmly goes to her crate and settles down. Can't recommend Dugie's Diamond enough to anyone in the Naperville area.
We used Ryan for crate training and potty training our new Labradoodle puppy. He was so patient and thorough in explaining everything. The day training format was perfect for our schedule.
Our aggressive Rottweiler had bitten two people before we contacted Ryan. He was the only trainer willing to take the case seriously. His behavior modification program was careful, structured, and incredibly effective. Ryan literally saved our dog's life.
As first-time dog owners in Plainfield, we were completely overwhelmed with our new Bernese Mountain Dog puppy. Ryan's in-home training program was exactly what we needed.
Ryan worked with our 2-year-old Doberman who had intense separation anxiety — howling, destroying furniture, the works. His systematic approach to desensitization was unlike anything we'd tried before.
We contacted Ryan for in-home training after our Beagle started resource guarding and snapping at our kids. He came out to our home in Aurora, assessed the situation calmly, and created a plan that the whole family could follow.
