If you’re like me, you were raised to think that all dogs should be sterilized. Veterinary school and our lives in practice further reinforced that truism. Dogs, we were reverently informed, require sterilization if they’re to live long, healthy lives. To fail to spay and neuter every pet, goes the mantra, is irresponsible and near tantamount to animal cruelty. For decades, it only made sense to me, too. Dogs, like humans, experience the probability of diseased reproductive organs.
