Common diseases in penis of Great Dane Dog

Here are some of the most common diseases in penis of a Great Dane dog:


When a penis can’t be expelled through the preputial orifice, it’s hereditary or acquired because of neoplasia, edema, fibrosis, or trauma. Clinical signs can vary.

Surgery is all that is needed to fix phimosis. The aperture of the prepuce is somewhat expanded so that the penis can be fully extended. In cases when urine pooling is not a concern and the pet is not being utilized for breeding, surgical repair may not be essential.


Paraphimosis is a condition in which the glans or penis cannot return to its original storage location within the sheath. Paraphimosis in Great Dane dogs can be caused by simple or complex factors, but it is always painful and can lead to significant complications if left untreated.

Paraphimosis can be easily treated if diagnosed early enough, before the edema and agony become unbearable. Gentle washing and ample lubrication of the exposed penis are the first steps in treatment. First, the prepuce is slid in a posterior direction, elongating the penis. Then, the penis is inserted into the prepuce.


Inflammation of the penile or preputial mucosa is known as balanoposthitis. Canine penile and preputial lesions, which account for around 20% of all cases, are frequently infected.

Several things such as Trauma, snake or bug bite can cause balanoposthitis in your Great Dane dog. Also, there may be a small object that is not part of the natural environment that can trigger it.

To treat it, it is recommended that any risk factors be addressed and that long hair at the preputial opening be shaved to make cleaning easier, as well as that a mild antiseptic (such as diluted povidone-iodine or chlorhexidine) or sterile saline solution be used to properly clean the preputial cavity.


Here are the answers about some questions related to Great Dane dog penis:

Great Dane dog penis health: what Is normal?

You must know what a healthy dog’s penis should look like before you can tell if something is wrong with it.

Many times, the skin and other tissues around a dog’s penis are actually the prepuce or sheath that you see on its outside. Mucous membrane covers the penis, making it appear moist and bright red or pink.

The opening of a dog’s prepuce can accumulate a modest amount of yellowish-white or even green-tinged discharge. Smegma is a common condition, and it’s quite natural.

Because of a bone termed the “os penis,” the canine penis is hard even when it is not erect.

On either side of the penis’ base, two glands known as the “bulbus glandis” reside. Blood builds up in the bulbus glandis when a dog is excited, causing two noticeable lumps.

Sometimes the entire engorged penis and bulbus glandis protrude outside the prepuce in dogs that have been neutered, despite the fact that they have been surgically removed from their penis and glands.

Note that the erection of a dog can last anywhere from a few minutes to around an hour.

Why Is my Great Dane licking his penis?

Dogs lick their penises for a variety of reasons, one of which is to keep them clean.

Sometimes, even if a dog is neutered, it will self-stimulate so much that it will develop an erection. Ignore this behavior unless you also discover issues with your dog’s penis or changes in his general health.

You should be on the lookout if your dog’s licking is excessive, especially when it’s linked with other symptoms such as an increase in discharge, pain, or lethargy.

If you have questions, contact your veterinarian.

What’s up with my Great Dane dog penis discharge?

A yellowish-green discharge or pus may come out of your dog’s prepuce. As explained by, this discharge contains cells and lubricant and protects the dog’s penis while it is in preparation. This discharge shouldn’t be seen very often, and only in very minute amounts.

It’s also possible that your dog is suffering from a urinary tract infection or canine cancer if he is licking his privates excessively and there is a lot of discharge coming out of his mouth. And if there’s blood in the fluid, take your dog to the clinic right away.

Why is my Great Dane dog’s penis stuck out?

Even if a dog has been neutered, he or she will have erections from time to time.

Generally speaking, if your dog’s penis is erect and visible for a short length of time but then returns to its regular position, you don’t need to worry.

However, dogs can have continuous erections or cannot retract the penis into the prepuce because of hair around the penis, neurologic issues, prostate disease, or anatomical anomalies.

Make an appointment with your dog’s vet as soon as possible if the penis is discolored or dries out.

If not treated right once, these conditions can lead to irreversible damage to the penis and difficulty urinating.
