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. The fact that he comes to your home to teach you the techniques is what makes this work long-term.
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. He taught us how to manage the biting, get potty training on track, and build a solid foundation of obedience. 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. And because Ryan taught me how to reinforce everything at home, the results have actually lasted. Worth every penny.
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. Ryan was incredibly knowledgeable and really took the time to understand our dog's specific triggers. 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 — drop off in the morning, pick up in the afternoon with a full lesson included. Our puppy is now fully crate trained and house broken at just 5 months old!
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. Six months later, our dog is manageable, safe, and actually enjoys meeting new people. 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. He came to our house, showed us how to set up structure, and trained us as much as the dog. Couldn't be happier with the experience and the results!
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. Within a month, we could leave the house for hours without incident. Grateful doesn't begin to cover it. Serving Joliet area too which was convenient for us.
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. Three weeks in and the guarding behavior is completely gone. Professional, knowledgeable, and genuinely caring about the dogs he works with.

Finding the right dog trainer can feel overwhelming — big-box pet store classes, cookie-cutter franchise operations, and trainers who train your dog but never teach you how to maintain the results. That's exactly the problem we solve.
Our unique hybrid approach combines professional day training with personalized in-home owner education. Your dog spends three focused hours with Ryan receiving expert-level training. Then, at the end of each session, Ryan comes directly to your home to teach you the exact commands, timing, and techniques your dog learned that day — so the results actually stick.
No more sending your dog away for weeks only to have them regress at home. No more competing for attention in a room full of other dogs. You get the best of both worlds — intensive professional training paired with one-on-one coaching in the environment where your dog actually lives.
Whether you're in downtown Naperville, Plainfield, Joliet, Aurora, or anywhere in the surrounding suburbs, we bring professional-grade dog training to your doorstep.
