About Adam Hartman, Your In-Home Dog Trainer
I’m Adam, the trainer behind Dog Principal. I work with dog parents across Maryland, Virginia and Washington DC, in your home and your neighborhood, where the problems actually happen.
How I Got Here
I used to work in finance. In 2022 I followed my passion and left that world to train dogs full time.
I completed the six-month program at Tarheel Canine Training School in Sanford, North Carolina, a police dog training program. After working dogs that tough, an aggressive pet dog doesn’t scare me. Then I spent a year and a half as a trainer at Woof Dogs in Palm Beach County, Florida, working with hundreds of dogs of every breed, age and temperament.
In 2024 I started Dog Principal. Today I’m based in Annapolis and train all over the DMV, with more than 750 in-home sessions and 60 board and trains behind me.
What I Do
I specialize in rehabilitating aggressive and difficult dogs: dogs that bite, guard their food and toys, react on the leash, or fight with other dogs. I also help with puppies, everyday manners and obedience.
That’s where the name comes from. I train the dog and the dog parent together, so your dog builds new habits and you know how to keep them going after I leave.
How Sessions Work
Your first session is 90 minutes: a 30-minute consultation plus an hour of training, for $175. Follow-up sessions are one hour, $175 each, booked one at a time. After your first in-home session, a two-week board and train at my home near Annapolis is also available.
