INGUINAL CANAL

Inguinal canal is a slit like space between the internal and external inguinal ring.

• Internal inguinal ring is formed by internal oblique abdominal muscle and external inguinal ring is formed by the tendons of external oblique abdominal muscle.
• In case of dog, bull and boar, internal inguinal ring is larger but they have short inguinal canal.
• In stallion, inguinal canal is longer but it has smaller internal inguinal ring.
