What are the benefits of spaying or neutering my pet?

Besides helping to reduce the overpopulation of animals, spaying and neutering conveys direct health benefits to your pet. Spayed and neutered pets are less likely to roam and fight. In females, early-age spaying drastically reduces the incidence of mammary (breast) cancer later in life, and in males, prostate and anal problems, hernias and testicular problems can be prevented. Older females that have not been spayed are at risk for uterine infections, which often go unrecognized by the owner, and may become life-threatening.
