I have used Karen Pearce with my GSD, and now the pup my GSD fostered.... I like her training style, and we see eye to eye on most things. She works for Petsmart (and Im not a Petsmart trainer fan), but I had met her in person before I knew she worked there and we are good friends now. She is at the Petsmart on 281N and Bitters. We are taking puppy classes right now every Saturday night, and will be starting Advance II calsses on Fridays in a couple of weeks too.
