#FEMALE DOG ANATOMY OUTSIDE SKIN#

The baculum bone can help the dog to copulate for longer, but it does not appear to be very useful in causing erections. This points to the two basic functions of a dog's penis which are eliminating urine and discharging semen.ДЄ dog's penis does become filled with blood when erect. The dog's penis is part of the urogenital system. The dog's penis has a bone called the вЂ baculumвЂ™ or вЂ os penisвЂ™, often referred to simply as the вЂpenis boneвЂ™. In the image below you can see the anatomical differences of the penis of various different species.

This is unlike the fibroelastic penises of animals such as ruminants and pigs. This type of penis is filled with a relatively large amount of blood at the time of erection. The penis of dogs is classified as musculocavernous, as are the penises of cats and horses. It is sometimes called the tip or the head of the penis. Glans (glans penis): this is the distal part of the dog penis where the entrance of the urethra is located.It is further divided into two parts, the corpus cavernosum (largest part which fills with blood during erection) and the corpus spongiosum (tissue surrounding the urethra inside the penis). Body (corpus penis): this makes up the greatest part of the dog penis.Root (cura penis): the root of the penis fixes this organ in the ischial arch.The three main parts of a dog's penis are: Under the prepuce, the sensitive penis is made up of different parts. Such damage could be in the form of physical trauma, as well as exposure to bacteria and other pathogens which can lead to disease.

The prepuce protects the penis from external elements which could cause damage to the relatively vulnerable penis tissue.

This is because the part which is normally visible is the prepuce, a covering of skin which is similar to the human foreskin. When we look at a dog's penis while flaccid, we cannot usually see it.
