This type of cancer is rare in dogs. It is not influenced by testosterone, so it can occur in both neutered and non-neutered male dogs.
The diagnosis of prostate enlargement is made by digital rectal examination, during which the size, position, and firmness of the prostate gland is assessed. Ultrasonography provides additional information and may be helpful in guiding a needle into the prostate to obtain a biopsy - a procedure indicated when cancer is suspected.
Treatment involves surgery and/or radiation therapy. In most cases the disease is far advanced by the time it is diagnosed. Because prostate cancer in dogs is not testosterone dependent, neutering does not slow the progress of the disease. Similarly, neutering does not protect against the development of prostate cancer.
There is no prevention for this condition.
