Prostate Disease in the Breeding Male Dog



For benign prostatic hyperplasia, treatment is only indicated for symptomatic dogs. Castration is the treatment of choice for animals with no breeding value, and this should effectively resolve the problem.


However, if the dog is valuable for breeding purposes, medications can be used to temporarily reduce the size of the prostate so that the dog can be functional. This treatment is typically only used to reduce clinical signs so that sufficient quantities of semen can be collected and frozen for future use. It is not meant as a long-term therapy, and without further treatment the prostate will return to pretreatment size eight weeks after discontinuation of therapy. Your veterinarian will likely recommend castration once the desired doses of semen are stored.


If the cause is found to be a bacterial infection, antibiotics will be prescribed, based on the specific culture and sensitivity results. If the infection is chronic, the antibiotics of choice will be designed to treat the more intense form of infection. Castration is recommended if the course of antibiotics does not get resolve the infection. If the diagnosis is a cyst, treatment will be based on the location, type, and size of the cyst. Again, castration may be recommended.


If the diagnosis is cancer, it has usually metastasized by the time of diagnosis. Chemotherapy may be advisable, depending on the nature of the cancer, but it is important to keep in mind that there is no cure or long-term remedy for cancer. Pain relief medication will be prescribed to help your dog to cope.


Living and Management


Your veterinarian will want to repeat the prostatic fluid cultures in follow-up visits. Semen evaluation should be performed in all dogs maintained for breeding, but not before 65 days after the resolution of bacterial prostatitis. The abdominal ultrasound will also need to be repeated in order to evaluate the prostate size after medical therapy.


Dogs that test positive for Brucella (Gram-negative bacteria) should not be used for breeding, as this disease is highly infectious. It is also important to note that Brucellosis is a zoonotic infection that can be passed from dogs to humans, although is remains an uncommon disease in humans. In the event that your dog is diagnosed with Brucellosis, you will need to take the necessary precautions when handling any secretions from your dog.
