Reactivity, dog aggression and resource guarding need a structured, hands-on plan. Most of these cases do best in a custom board & train.

We recommend
ADA-compliant service dog training for PTSD, TBI and mobility, built around the handler’s individual needs.
Training programs
From your first puppy class to advanced obedience and service work, every program is built on the same thing: clear communication, real-world proofing, and training the handler as much as the dog.
Our flagship program
Your dog lives and trains daily with the Riedel K9 team, in our facility and out in the real world, and you come weekly for a private session so you can keep it going at home.
Levels 1 · 2 · 3
Five-week, hands-on classes that take you and your dog from the basics to rock-solid obedience around real-world distractions.
One-on-one coaching
Focused, customized sessions built around your dog’s specific issues and your goals, at your pace.
Exercise + training
A full day of supervised exercise plus a customized training session, so your dog comes home tired and better behaved.
Reactive & problem dogs
Leash reactivity, dog aggression, resource guarding, nervousness: the cases other trainers turn away are what we do every week.
ADA-compliant training
Service dogs for PTSD, TBI and mobility, trained to ADA requirements and to the handler’s individual needs, with the handler brought in every step of the way.
Call the office and tell us about your dog. We’ll recommend the right program, no pressure.

Why Riedel K9
Nelson Miller didn’t learn dog training from a weekend certification. He came up through police K9 and search-and-rescue training, works service dogs for veterans, and titles his own dogs in sport and work. That depth shows in every family pet that comes through our doors.
Board & train transformations
A few of the dogs who’ve come through our board & train program, in our own words from their graduation posts.
Mika
Working Shepherd
Dog reactive, chicken reactive, zero impulse control.
Loving life with new boundaries and solid obedience, all while wagging her tail.
Sully
Rescue Greyhound
Fought and bit at anything on the leash.
A heeling pro, heading out on all the adventures he was missing.
Winston

Working closely alongside other dogs and obeying commands.
Koda
Rottweiler
A big boy with big puppy energy.
Controls himself on and off leash, ready for life with his mom.

Baylee
Board & Train
Jumping, running off and pulling.
No more jumping, no more running off, no more pulling.
Tally

Needed obedience, behavior mod and confidence.
Off-leash reliable at the park, and now she’s learning to paddleboard.

Don’t take our word for it. Here’s what Delmarva dog owners say after training with Nelson and Amy.
“I took my female German Shepherd here for the board and train program, and she came back as a completely different dog. She used to not let anyone in certain rooms in the house, and now has no problems — as well as made it possible for her to go on walks surrounded by other dogs, without any reactivity. I would 100% send any of my future dogs back without hesitation.”
“Nelson and Amy are knowledgeable and patient and willing to help correct you and your pup to make sure both the handler and trainer are trained! We did all three levels this year, and Jack is a whole new dog! I’ve had plenty of family members say that they can’t believe how much our Jack has improved.”
“Very professional, highly skilled, and they help not only your dog, but you and how you handle your dog. I took both of my dogs there, one is very problematic with many issues. Nelson worked a mini miracle helping my dogs integrate into my home life in a safe and effective way. It has been a blessing in my life.”
“Their care and love for dogs is apparent from the very beginning. I was apprehensive about leaving my pup with someone else, but after seeing their interaction at our first training session I was immediately put at ease. As the weeks progressed and I could see the changes in my dog and the bond he had formed with Nelson, I was blown away. They worked no less than a miracle.”
“After losing our daughter, Clary’s human, it was incredibly hard to let her go into someone else’s care, but Riedel K9 truly embraced her like family. We’re beyond grateful for the trust we could place in them, and seeing her walk with us on leash now is just a beautiful gift.”
“I have a 100lb plus 2yr old Great Pyrenees female with an attitude. Resource guarding major issue. Tried medication route, limited success. Beautiful kennel and indoor climate-controlled training facility. Spotless. Our girl was with Nelson 4 weeks. Excellent results.”

In a board & train, your dog lives at our facility and trains daily with the Riedel K9 team, both at the facility and out in public places like stores, parks and trails. You come in weekly for a private training session with your dog, so you know how to keep the results going at home.
Yes. Leash reactivity, dog aggression, resource guarding and fear-based behavior are a big part of what we do, through board & train, behavior modification and private lessons. For safety, dog-aggressive or people-aggressive dogs can’t attend group classes, but we’re happy to work with them privately.
Level 1 covers place, sit, down, stay, heel and recall at the beginner level. Level 2 adds distractions, impulse control and proper behavior. Level 3 is advanced obedience with high distractions at public locations, off-leash where permitted.
Our training is led by our Training Director, Nelson Miller, a graduate of Highland Canine School for Dog Trainers’ Police and SAR program.
