Many veterinary surgeons believe that neutering not only helps solve the serious problem of unwanted pet overpopulation but also makes for friendlier, easier-to-live-with pets. Spayed female dogs are more relaxed, while neutered males are less likely to roam, ‘spray’ or urine-mark their territory, or fight with other males. Plus, sterilisation has health benefits – it helps to minimize the risk of cancers of the reproductive organs and the mammary glands in females and reduces the incidence of prostate and testicular cancer problems in males

Spaying removes the uterus and ovaries of a female dog, often around the age of six months. A major surgical procedure, it is performed under general anaesthesia. Complications are rare and recovery normally is complete within two weeks.

Castration, also carried out under general anaesthesia, removes the testicles of a male dog through an incision at the base of the scrotum. Usually performed when the puppy is about six months old, it necessitates only a brief hospital stay. Full recovery takes about seven to ten days.
