Benign Prostatic Hyperplasia in Dogs

The prostate gland is an essential part of the male reproductive system, secreting a liquid that contains simple sugars, citric acid, calcium, and a number of enzymes that work to balance out and protect the seminal fluid, aiding in its motility and survival so that it can fertilize a viable egg.

Benign prostatic hyperplasia (BPH) is a common age-related problem in dogs. Hyperplasia, as a medical condition, is the indicative term used to describe an abnormal growth in the number of cells in any organ. In this case, the prostate gland. When the condition is of a benign nature, enlargement of the prostate gland does not cause pain in the dog.

This condition is commonly seen in intact dogs around 1-2 years of age. Incidence typically increases with age, affecting an estimated 95 percent of dogs by the time they reach nine years of age.

Symptoms and Types

Most dogs do not show any symptoms at all. Following are few of the possible symptoms related to this condition:

• Bloody discharge from urethra
• Blood in urine
• Blood in ejaculate
• Difficulty in urination
• Difficulty with defecation
• Ribbon like stools
• Other symptoms may be present if a prostatic infection or carcinoma (malignant tumor) develops

Causes

• Age related; usually affects older dogs
• Hormonal imbalances

Diagnosis

You will need to give a thorough history of your dog's health and onset of symptoms. Your veterinarian will perform a thorough physical exam on your pet, with standard fluid samples taken for laboratory analysis, including a chemical blood profile, a complete blood count, and a urinalysis.

Laboratory tests will commonly return positive results of blood in the urine. Pus or bacteria may be also present if an infection is present. Your veterinarian will take a sample of prostatic fluid through ejaculation or by prostatic massage which may show the presence of blood. Further diagnostic testing will include X-ray and ultrasonography imaging, which will help your veterinarian to determine the size of the prostate gland, and to estimate how the size of the prostate is affecting your dog. Using the ultrasound as a guide, samples can also be collected directly from prostate gland for analysis.
