Causes and Treatment of a Dog Bleeding from Penis


Canine penile bleeding can be a symptom of a spectrum of dog health disorders. This can include injuries, urinary tract infections, urinary tract calculi (stones), neoplasia, or cancerous and/or cystic growths in the urinary tract. The most common reason for dog bleeding from the penis is a prostatic disorder, which means that patient is suffering from a disease or disorder in the prostate gland.

Infections, enlargement of the gland and prostate cancer can cause bleeding from the penis. The condition is not always as simple as it seems, therefore it requires detailed clinical and laboratory diagnosis before any specific treatment is initiated. If you observe excessive penis licking or symptoms that aren't normal for your dog, see a veterinarian. Supportive measures such as natural remedies for prostatic health and urinary tract strength/health are usually very effective in reducing symptoms.

Overview of Causes

There are a number of reasons that could cause a dog to bleed from his penis. These include but are not limited to: infections, injuries, urinary tract calculi (stones), cancerous developments, cysts and most common of all, prostatic diseases (prostate gland).

The urinary tract is comprised of several sections. The canine penis is the terminal organ (end) of the urinary tract and blood may pass through it if any part of the urinary tract is affected by infection, tumors, cysts or calculi (stones). Bleeding from a canine penis is a common sign seen in urinary tract infections, cancerous developments and calculi accumulation. In the aforementioned causes of dog penis bleeding, it is common to notice blood when the dog is urinating.

Persistent bleeding from dog penis is commonly associated with prostatic diseases and problems with the dog prostate gland. Prostatic diseases such as benign hyperplasia, prostatic abscesses, bacterial prostatitis, prostatic cysts and prostatic adenocarcinomas are common reasons for bleeding from a dog penis.

The likelihood that urinary tract infection or prostatic diseases are the cause increase if you observe any changes the way a dog normally defecates or urinates. This includes straining or frequency of urination or defecation.

In the spectrum of causes, another common reason for bleeding from the penis in dogs is blood clotting and other hemolytic disorders. These are related to chronic circulatory deficiencies and blood disorders.

Clinical Symptoms

A dog bleeding from his penis is only a clinical feature of another underlying health disorder, which is typically accompanied by other signs and symptoms. A dog with a urinary tract infection or calculi accumulation may show symptoms such as abdominal pain, urinary incontinence, painful urination, and blood mixed with urine. In cases of infection, a dog may bleed from the penis at the end of urination, while a dog with calculi in the urinary tract may urinate with fresh blood mixed in it.

Signs of persistent bleeding from a canine penis are mostly noted in prostatic diseases, where a dog has an enlarged prostate gland which can be detected by abdominal and rectal palpation (a veterinarian can feel the enlarged dog prostate by feeling the dog).

Canine prostate tumors and cysts and urinary tract infections that are in advanced stages of disease usually bleed persistently and a dog may show signs of bleeding from the penis. Common signs such as fever, anorexia, discomfort, penis stiffness, malaise and abdominal pain are usually also noted in urinary tract and prostatic bacterial infections, tumors and cystic developments.

In cases where a dog is suffering from circulatory deficiencies and blood clotting disorders, the patient may need to be diagnosed with special blood tests. 


If a dog's penis is bleeding he should immediately see a veterinarian for a detailed examination and specific treatment. A veterinarian will record a detailed history of the condition and conduct a thorough examination.

The vet may need to perform several tests, as it is essential to detect a possible underlying disease in order to make an accurate diagnosis. These initial tests can include a urinalysis and urinary tract X-Rays. Infection, calculi and prostatic disease can be clearly detected by these tests, but further confirmation may be needed in more complicated cases, including ultrasound and various advanced cytological and microbiological examinations, in order to get accurate confirmation of the diagnosis.

Treatment for Canine Penile Bleeding

Once a clear diagnosis is made by a veterinarian, the underlying cause should be treated accordingly. Infections can be treated with broad spectrum antibiotics and supportive drugs. Similarly, surgical procedures may be needed for more complicated cases of calculi accumulation (stones) and prostatic enlargement. Neutering a dog is one of most successful techniques used to treat symptoms of dog bleeding from penis.

Supportive measures are essential along with specific treatment prescribed by the veterinarian; natural remedies such as Prospet Drops and Kidney Support, herbal extracts and supportive therapeutics prescribed by a veterinarian may help in speeding the recovery from a case of dog bleeding from penis and simultaneously reduces chances of common secondary problems.
