Nor will neutering or spaying cause a dog to become lethargic, although if a male has been putting all his energies into pursuing lady dogs with lust in his heart. Some folks tend to anthropomorphize their pets. So they see the act of neuteririg a male as somewhat dcgrading and robbing him of his macho nature. Or they regard spaying as depriving their female of maternal rights, taking away her femininity. This is so wrong.
Dogs are dogs and people are people.
Dogs don't even understand romance - candlelight and soft music are wasted on them. Please don't attribute your own beliefs about sexuality to your pet. Instead, think about what's best for his or her life with you, and his or her life in society. There are many sound medical reasons for considering neutenng or spaying. Dr. Milts discusses them in his article on health, elsewhere in this issue.
