Neutering refers to the surgical sterilization of dogs, both male and female. For females it is usually referred to as spaying. Reproductive organs are removed to prevent an overpopulation of dogs. Typically, there are no problems following the surgery, but you should be aware of possible changes in your dog.

Disposition
-
Neutering can eliminate the unwanted behaviors related to mating, such as the anxious behavior of a female dog in heat and the aggressiveness of a male dog in his search for a mate.
Metabolism
-
Although the Dog Owner's Guide indicates that neutering can increase your dog's tendency to become obese, the American Veterinary Medical Association says that neutering does not make your dog fat. A balanced diet and appropriate exercise will help keep your dog at a healthy weight.
Disease Prevention
-
Neutering can reduce or eliminate your dog's risk of certain diseases, such as uterine infections, testicular cancer and breast cancer.
Disease Risks
-
Although there is a reduced risk of certain diseases, the Dog Owner's Guide indicates that spayed females are at a higher risk of joint problems, thyroid disease and some types of cancer.
Considerations
-
Some dogs may have complications during their recovery, such as a negative reaction to the material used for sutures or failure of the incision to properly heal. It is important to observe your dog carefully following surgery and report any concerns to your veterinarian.
