Dogsitting Position.

Dogsitting Position.
The dog sitting position is a descriptive term for a fetus in anterior presentation, and dorso-sacral position, whose hind legs are extended and enter the pelvic inlet. Correction is very difficult unless the front half of the fetus can be repelled and the fetus extracted by the hind legs. Traction on the front limbs with partially repelled hindlimbs can result in perforation of the uterine wall below the pubic brim.
