Charlie, a Peek’n Puppy graduate. “We wanted to thank you for the excellent service you provided while training our little Shih Tzu Charlie. It is such a relief to see the difference your knowledge, expertise and training has made in our lives. Your method of using nothing but positive reinforcement worked beautifully and we are now the relieved, contented and grateful owners of a happy, obedient (and still feisty ) little guy.” -Ray and Nikki R., Rio Rancho, NM
