What are the sesamoid bones in dogs?

Sesamoid bones in dogs are small, round bones located within tendons, primarily to reduce friction and improve the mechanical function of the joints. The most notable sesamoid bones in dogs are the patella (kneecap) and those found in the paws, such as the proximal and distal sesamoids associated with the metacarpal and metatarsal bones. These bones play a crucial role in aiding movement and providing stability during activities like running and jumping. Additionally, they help absorb shock and distribute weight across joints.
