The invention relates to a teeth cleaning bone for pet and a manufacturing method thereof. The teeth cleaning bone comprises a cylindrical leather roll wound by a core roll and an outer cover and an equal-length cotton cord helically wrapping around the leather roll to form a twist-shaped combination, in which two ends of the twist-shaped combination structure are respectively fixedly tied with knot-type heads so as to form a bone-shaped structure as a whole. After the two knot-type heads of the bone-shaped structure are structurally trimmed, a bracing-stretching device is utilized to brace and stretch the two knot-type heads of the bone-shaped structure so as to form a firm structure the bone-shaped structure is then treated with a sterilization procedure at high temperature for more than three hours and subsequently treated by a drying procedure for twenty hours so as to harden and shape the leather roll and the two knot-type heads. Accordingly, the hardened leather roll and the flexible cotton cord are firmly combined into a bone-shaped teeth cleaning bone structure characterized with flexibility and rigidity, in which the teeth cleaning bone is capable of grinding and cleaning pets teeth when the pet is attracted to tear and bite the bone, and providing use inventiveness of chewing flavor function moreover, due to the leather roll formed by more than two layers of wrapping and winding structures, the teeth cleaning bone is endurable and not easily ruptured torn and bitten by pets, featuring of multiple inventiveness of durability and longevity.本發明係為一種竉物潔牙骨及其製造方法,包含一由芯卷與外皮捲成一圓柱狀的皮卷,與一條等長的棉紗繩以螺旋纏繞成麻花狀結合,於兩端分別以打結固定形成結狀頭之結構,而整體呈骨頭造型之結構,經適當結構修整後將兩端結狀頭以一撐張裝置頂撐使結構更牢固,繼之再以高溫進行三個小時以上的殺菌程序,及廿個小時的烘乾程序,使皮卷及兩端結狀頭硬化定型;俾硬化的皮卷與軟性的棉紗繩牢固組成軟硬交錯兼具之骨頭造型潔牙骨結構,能吸引寵物把玩撕咬時達到磨牙與潔牙時,同時具有咀嚼味道功能之使用進步性;且皮卷以雙層以上包覆捲繞的結構可耐久撕咬不易破裂,兼具耐久使用之多重進步性達成者。10...潔牙骨10...皮卷13...棉紗繩14、15...結狀頭
