BRAND STORY
Three pets in the family. A long-term pursuit of healthier years.
Mugua, Tuhao and Katy led us to think seriously about how pets grow, age and live well for longer. Dr.GTDs uses science and long-term R&D to help dogs and cats live freer, healthier everyday lives.
WHO WE ARE
Shanghai Gua Tu Di Trading Co., Ltd.
Healthy longevity is our long-term direction, with functional treats and nutritional support at the center of our research. Our team brings experience in veterinary ingredients, scaled manufacturing and quality systems, alongside university research collaboration. Cat litter and grooming products also address everyday care needs in pet families.
OUR NAME / GUA · TU · DI
Gua Tu Di is our family.
Gua comes from Mugua, Tu from Tuhao, and Di comes from 蒂 (di), the second character in Katy's Chinese name (凯蒂). Together they became Gua Tu Di. GUA + TU + DI forms GTDs, a name that now stands for every pet we call family.

Watching them grow made us take aging seriously.
Pets do not become old in a single day; change appears quietly across ordinary routines. You reap what you sow. For Gua Tu Di, that means investing time, functional nutrition research, disciplined quality management, validation and patience until they grow into products designed to support healthy aging in everyday life.
Invest in ingredients, formulation and evidence
Bring meaningful support into every day
HEALTHY LONGEVITY
Help more pets reach 20+ in good health.
Twenty-plus is not a promise about any individual pet's lifespan. It is the long-term direction behind our R&D: not simply adding years, but supporting more years with mobility, appetite, curiosity and quality time together.
What we truly hope to extend is the time we live well together.
GTDs
Growing Together. Driven by Science.
Growing Together is the life pets and people share. Driven by Science is how we take responsibility for that time. GTDs comes from GUA, TU and DI, while also standing for every pet treated as family and supported by science.
