    Study Notes

    Female Canine Reproductive Structures

    • The vulva's labia are supplied by the internal and external pudendal arteries.
    • The clitoral fossa is a depression near the ventral commissure, containing the clitoris.
    • The clitoris is homologous to the male penis and has erectile tissue.
    • In mares, clitoral sinuses are on the glans' periphery.
    • The vestibule is between the vagina and vulva, housing the urethral tubercle, external urethral orifice, and vestibular bulbs.
    • The urethral tubercle is a ridge at the vestibulovaginal junction, unique to dogs.
    • The dorsal tubercle is the vaginal entrance, and the ventral tubercle leads to the urethra.
    • The ventral tubercle is a landmark for urinary catheter placement.
    • The external urethral orifice is the urethra's external opening.
    • Vestibular bulbs are erectile tissue within the vestibule, constricting during copulation.
