Prostate Enlargement in Dogs




The course of treatment your veterinarian prescribes will vary with the underlying cause of the prostatomegaly. Surgical castration is indicated in symptomatic dogs with benign enlargement. Acute (sudden and severe) infection, with bacterial prostatitis (inflammation of the prostate gland), will usually be resolved with antimicrobial medication.


Surgical drainage is indicated for dogs with prostatic abscess or large prostatic cysts.


External beam radiotherapy may provide relief of pain in patients with prostatic carcinoma. The medications your veterinarian prescribes will be suited to the specific needs of your dog.


Living and Management


Your veterinarian will want to perform additional abdominal radiographs or prostatic ultrasonography to assess whether the treatments are working and progress is being made. Urine and prostatic fluid cultures will also be conducted to assess whether the antimicrobial treatment is working in patients with bacterial prostatitis.
