Old man's gland - Do dogs have the same problems as humans?

Prostate disease in the dog

The prostate is the only accessory sex gland in the male dog. It is a butterfly shaped structure that surrounds the urethra (the tube that connects the bladder to the outside). Due to the location of the prostate, it can affect the urinary system, the colon and the hind legs, as well as having some systemic effects. Prostatic fluid is produced continuously in the dog. Prostatic fluid makes up most of the volume of seminal fluid (the fluid that carries semen). The prostate has many nerves and blood vessels running to it but is surrounded by a thick capsule, which sometimes makes it difficult for some drugs to get deep down into the prostate. Normal prostatic function is dependent on circulating testosterone. The prostate can develop a few conditions that can result in debilitating disease in the dog.
