The digital rectal examination is a relatively simple medical procedure. The patient undresses and is then placed in a position where the anus is accessible (lying on the side, squatting on the examination table, bent over it, or lying down with feet in stirrups). If the patient is lying on their side, the physician will usually have them bring ...

The prostate is the only accessory gland that occurs in male dogs. [65] Dogs can produce in one hour as much prostatic fluid as a human can in a day. They excrete this fluid along with their urine to mark their territory. [66] Additionally, dogs are the only species apart from humans seen to have a significant incidence of prostate cancer. [67]
Testicular cancer is rare in dogs, and also prostate problems are somewhat common in castrated male dogs when they get older. [140] Neutered individuals have a much higher risk of developing prostate problems in comparison to intact males. Castrated male cats are more likely to develop an obstruction in their urethra, preventing them from ...
However, the incidence of adverse reactions for neutered and intact dogs combined is only 0.32%. [53] Neutered dogs have been known to develop hormone-responsive alopecia (hair loss). [54] A 2004 study found that neutered dogs had a higher incidence of cranial cruciate ligament (CCL) rupture, a form of anterior cruciate ligament (ACL) injury. [55]

Most dominantly aggressive dogs are male, which causes many people to neuter their male canine companions. Removing testosterone can decrease the intensity of a canine's reaction to stimulus. Testosterone does not cause a behavior to occur, but its absence may decrease the occurrence of a "bad" behavior.
The male hormone, testosterone, is produced in limited quantities following treatment with Zeuterin, but after two years, testosterone production is similar to that in untreated dogs. [1] The continuing presence of testosterone means that, unlike surgical castration, chemical castration does not remove the risk of testosterone-associated ...
