The invention discloses a machine processing method of a laminated bone-shaped dog gum. The processing method comprises the following steps: at first, drying a processed animal leather by an air dryer; then fixing one end of one or more dried animal leathers on a rotation machine, starting the rotation machine to roll the animal leather into a long roll, wherein the interior of the long roll has a layered structure; then cutting the long roll into segments with a preset length by a cutting machine; and finally punching the segments into bone-like articles in a punching machine. The bone-shaped dog gum is made of one or more animal leathers, the middle of the dog gum is in a layered structure, and no small particle exists in the middle of the dog gum, so no shred falls when dogs bite the dog gum. Moreover, the dog gum is produced by machines, the time is saved, and compared with artificial operation, the work efficiency is improved by 8 times or more.
