If you have an intact (unneutered) male dog, one of the primary medical conditions our veterinarians will need to screen for is prostatitis and the potential development of a prostatic abscess. Prostatitis is an inflammation or infection of the prostate gland, predominantly seen in older, unneutered males.
While finding blood in your dog’s urine can be alarming and stressful for any pet owner, it is a critical clinical sign that requires immediate medical attention. The good news is that with proactive monitoring and prompt intervention from your veterinary team, these prostatic conditions can be managed effectively.
What is Prostatitis, and What are Prostatic Abscesses?
Prostatitis is a severe inflammation of the prostate gland. While it can theoretically affect any male dog, the risk is exponentially higher in older, intact males due to years of continuous testosterone exposure.
If left untreated, prostatitis can escalate into a prostatic abscess—a localized, sealed pocket of purulent material (pus) within the prostate gland itself. This dangerous complication is typically the result of chronic glandular enlargement (Benign Prostatic Hyperplasia) driven by a long-standing excess of reproductive hormones, paired with an undetected bacterial infection.
Recognizing the Clinical Signs of Prostatic Disease
Clinical signs of prostatitis vary with the severity of the infection and whether the disease is acute (sudden) or chronic. Please schedule a medical assessment immediately if you notice any of the following symptoms:
- Cloudy or bloody discharge from penis
- Straining to urinate or defecate
- Blood in the urine
- Abdominal discomfort or guarding the belly when touched
- Stiff gait
- Weakness/lethargy
- Fever
- Anorexia/vomiting
- Weight loss
- Chronic intermittent urinary tract infections
Common Causes of Prostatitis/A Prostatic Abscess
While there is no specific breed predisposition for this disease, age and reproductive status are the ultimate determining factors. Intact dogs between the ages of 7 to 11 years are at higher risk.
Some of the risk factors for this condition are:
- Presence of functional testicles (testosterone hormonal excess)
- Systemic bacterial infections spreading through the bloodstream.
- Bacteria migrating up the urethra from a lower urinary tract infection.
- An enlarged prostate (Benign Prostatic Hyperplasia)
- A compromised immune system
How Your Veterinary Team Diagnoses Prostatic Disease
Your veterinary team will perform a comprehensive physical exam. A rectal exam is an integral part of the physical exam when suspecting prostatic disease. Prostate issues often impact a dog’s overall health. Thus, the diagnostic standard of care requires pairing comprehensive bloodwork with a complete urinalysis.
To get a complete picture of the prostate’s size and structure, your veterinary team may utilize abdominal radiographs (X-rays) or an ultrasound—using a gentle probe on the belly to visualize the internal architecture of the gland. A digital rectal exam is also necessary to physically palpate the prostate. Because a swollen prostate is incredibly painful, your veterinary team may recommend Pre-Visit Pharmaceuticals (PVPs) like Gabapentin or Trazodone, or provide mild sedation during the exam. This aligns with our Fear Free philosophy to keep your dog’s stress and pain below their threshold while obtaining vital diagnostic information.
Preventative Care and When to Act
Benign prostatic hyperplasia is usually the primary disease. This is fueled by the hormonal (testosterone) flow; an abscess is usually a side effect of chronic unmanaged/untreated primary disease. Surgical castration (neutering) is the veterinary gold standard and an essential component of the treatment plan along with a course of antibiotics. The choice of antibiotics may depend on the urine culture results. In severe cases of a prostatic abscess, surgical draining of the abscess may be required.
Prostatic disease diagnosis, management, and treatment may represent a significant financial investment in your pet’s health, utilizing comprehensive pet insurance is highly recommended. Having insurance in place removes the financial stress of emergency care, allowing your veterinary team to provide the highest standard of surgical and medical intervention without compromise.
The Importance of Neutering for Prevention
The most definitive preventative measure against prostatic disease in male dogs is to have them neutered at an appropriate age. This routine surgery mitigates the risk of prostatitis and entirely eliminates the risk of testicular cancer, setting a healthy, medically sound baseline for their senior years.
Urinary and reproductive issues are rarely something you should “wait and see” about. If you notice your dog straining to urinate, dripping blood, or exhibiting abdominal pain, this can rapidly escalate into a life-threatening medical emergency (such as a complete urethral obstruction). Do not wait to see if the symptoms clear up on their own. Contact your veterinary team immediately for a medical assessment.
