現今寵物狗與人之間的關係日趨緊密，親暱的動作也更加頻繁，如何使人犬互動之餘能夠注重衛生清潔。寵物狗首要注重口腔清潔、皮膚和體毛的清潔，以及各項疾病的預防。然而，寵物美容至今已非常普遍，寵物醫療也對於疾病的診斷更為精密，所以在此先針對寵物狗口腔潔牙的重要性做探討。 本研究始自文獻探討口腔牙齒的構造及功能、口腔疾病、狗的心理層面、狗的行為反應以及市售潔牙產品；進而透過問卷調查、分析及歸納受測者使用現有產品替寵物狗清潔牙齒的困難所在，並在訪談專業醫師之後，依其建議之論點考量、市售寵物狗口腔清潔及習見潔牙具之設計，發現相對立之觀念差異。 全文探討寵物狗口腔清潔二個不同層次的潔牙模式：1.握柄牙刷2.指套牙刷，惟此種差異屬於對狗之心理之設想而產生操作上之不同，在潔牙之「需求本質」上並無對立之意涵。進而設計創作較佳之寵物狗泛用潔牙具，完成二種不同式樣之潔牙工具。
