Male vs Female Dog Anatomy Diagram - Key Physical Differences #1422343 (License: Personal Use)

This black-and-white line drawing clearly contrasts the rear anatomy of male and female dogs, with labeled sections indicating the penis, scrotum, vulva, and anus. The male diagram shows external testes and a more prominent penile structure, while the female displays a vulvar slit positioned closer to the tail base. Both figures include a decorative collar tag for visual consistency.

Used in veterinary education, pet care guides, or breeder resources to help owners or students identify sex in dogs-especially useful for puppies or when external features are ambiguous. Matches user intent for learning canine biology or confirming gender before adoption/spaying/neutering.
