What it is and what it does

In the male dog, the prostate is a large, bilobed gland that completely surrounds the prostatic urethra, the first part of the pelvic urethra, immediately after the neck of the bladder. Unlike the cat, the dog has no preprostatic urethra and no bulbourethral glands. It lies at the pelvic inlet, ventral to the rectum; its position changes as the bladder fills.

Worth remembering

Its position changes as the bladder fills; it lies below the rectum.
