Many people think it makes pets fat and lazy, or that pets miss breeding. However, any veterinarian will tell you that none of this is true. Spaying and neutering are simple, almost always complication-free surgeries from which pets recover from easily and with little pain. Although females often stay overnight after the operation, males can in most cases go home the same day. All dogs, especially males, become calmer and less dominant, losing the desire to roam and fight.
Training becomes easier and dogs are happier and less frustrated.
Spaying and neutering also lengthens your dog's life. For males, fighting is less likely, preventing the injuries that may be caused. The surgery prevents many types of cancer. Pet overpopulation is a serious issue.
