The development of the polished retriever is largely a factor of time invested in a dog of normal or above normal aptitude.
Polish arises from an attention to details.
Details promote quality, and quality exceeds expectations. Polish is more than style. It is a dog's functional behaviors, skills and responses that contribute to a satisfactory day in the field. Polish includes many dimensions, such as smooth delivery to hand, crisp handle, responsiveness, steadiness to shot and fall, tracking cripples, etc. They accomplish commands quickly in a crisp, stylish manner.
