What is the primary reason for spaying or neutering pets?

The primary reason for spaying or neutering pets is to prevent unwanted litters and reduce health risks. Spaying (the removal of a female's ovaries and uterus) and neutering (the removal of a male's testicles) effectively control the pet population, thereby reducing the number of animals in shelters and decreasing the incidence of euthanasia for unwanted pets.

Additionally, spaying and neutering have several health benefits. For instance, spaying can prevent uterine infections and reduce the risk of breast tumors, especially if performed before the first heat cycle. Neutering can help prevent testicular cancer and certain prostate issues.

While enhancing behavioral training, improving appearance, and increasing lifespan may all be associated benefits of spaying and neutering, the primary focus remains on responsible pet ownership by controlling the population and promoting overall health.
