This paper aims to explore the innovative application of the color patterns of the Dongna Tibetan clothing in pet product design. By systematically refining, analyzing, and designing the shapes and colors of the Dongna Tibetan clothing, we aim to integrate them into pet product design. As the pet economy grows rapidly, the diversity of pet product design offers consumers more options. Incorporating the color patterns of Dongna Tibetan clothing into pet product design not only enhances the ethnic, innovative, and diverse nature of pet products but also enables the sustainable development and preservation of Dongna Tibetan culture, allowing Dongna Tibetans to achieve creative regeneration in contemporary social settings.
