Gerard has proven to us that you can “teach an old dog new tricks.” We are grateful that the “tools” Gerard gave us to train our 7-year-old Jack Russell Terrier, Katie, made such a big improvement in her behavior in just a month. In just a few short weeks she changed from an aggressive, anti-social, fearful barker to an obedient, calm, friendly, social dog. The change in her has amazed our friends and neighbors. And Katie is enjoying all the extra attention because she is so well-behaved. Thank you, Gerard!
