An investigation into the relationship between human beings and Norfolk terriers

Two Norfolk Terriers were used as experimental subjects to investigate the means by which human beings relate to Norfolk Terriers in maintaining their overall dental health. The study was divided into two parts: the Hard Cheese Study (HCS) and the Oral Hygiene Study (OHS). The difficulties in conducting experiments on this breed are highlighted and an evaluation of random error in measurements is undertaken using an Index termed Jaw Occlusions in a Kennel Environment (JOKE).
