Brachydog is a general term for a type of dog breed with relatively short limbs and body, such as Corgis, Basenjis, etc. Because short-legged dogs have shorter limbs, their body center of gravity is lower, so they are relatively stable and less likely to fall. Additionally, their skeletal and muscle structure is relatively specialized to accommodate their body shape and gait.

Short-legged dogs usually have a very lively, friendly and affectionate personality, so they are one of the most popular pets. Despite their small size, they are often very brave and alert, adapting well to family life and forming deep emotional bonds with family members.
