While it is performed under a general anesthesia, it is a simpler surgery than a spay. An incision is made near the front of the scrotum, then the testicles are removed through that incision.
A common misconception is that it's not as important to neuter a male pet as it is to spay a female pet. Getting your pal neutered is every bit as important for preventing homeless and unwanted animals. Neutered males get many of their own physical and behavioral benefits - which can help give them a longer, happier life.
Neutering your pet can add an average of 3 to 5 years to his life.
Neutering does not change a dog or cat's personality or alter their protective instincts.
