Posterior Displacement of the Bladder in Dogs

Pelvic Bladder in Dogs

Pelvic Bladder in Dogs refers to the displacement of the bladder from its normal position, often accompanied by alterations in its size and the position of the urethra. This condition predominantly affects young intact female dogs, sometimes causing urination issues, although some dogs with pelvic bladder may not display such symptoms.

Pelvic bladder is more frequently observed in dogs compared to cats, likely due to the shorter length of the urethra in dogs. While it can occur in dogs of both genders, whether they are intact or neutered, it is more prevalent in intact females under one year of age. In male dogs, it typically becomes evident after neutering.

Symptoms and Types

While some dogs may not display any symptoms, others may exhibit the following:

  • Involuntary passage of urine (urinary incontinence)
  • Difficulty urinating, only able to release a few dribbles at a time
  • Urgent need to urinate without being able to pass urine
  • Urine scalding of the tail and surrounding area


The displacement of the bladder from its typical position may stem from a congenital defect (birth defect). It is also believed to be linked to obesity in certain dogs and is commonly associated with urologic abnormalities, aside from the evident incontinence.


To diagnose the condition, you will need to provide a comprehensive history of your dog’s health, including any symptoms experienced. Following this, your pet’s veterinarian will conduct a thorough physical examination. Laboratory tests such as a complete blood count (CBC), biochemistry profile, and urinalysis will be performed. If there are suspicions of infection, your veterinarian will collect a urine sample for culture to identify the causative organism. Urinalysis may reveal signs of urinary tract infection, such as the presence of pus, blood, or bacteria in the urine.

Additional diagnostic procedures may involve abdominal X-rays and contrast cystourethrography. This radiographic examination of the urethra and urinary bladder, after the introduction of a contrast medium, can reveal abnormalities such as a short, widened, or irregularly shaped urethra. Your veterinarian may also perform an ultrasound to examine the kidneys and urinary bladder for stones, masses, kidney distention, and other urinary system abnormalities.


If there are underlying urinary infections, your dog’s veterinarian will prescribe antibiotics to address them. Surgery will be necessary to reposition the displaced bladder and urethra. In some cases, antidepressants may be prescribed to help calm the animal.

Recovery and Management

Regular follow-up visits with your pet’s veterinarian are necessary to monitor the progress of treatment and detect any potential complications. If your dog has urinary infections, they may need regular antibiotic medication until the infection clears up. Keep a close eye on your dog for any unusual symptoms and contact your veterinarian promptly if anything concerning arises. Your veterinarian will also provide information about the common side effects associated with medications used in these cases.
