In ancient times, just as today in third-world societies, dogs lived miserable lives with little or no human care, which led to the hard-times expressions, “it’s a dog’s life,” “sick as a dog,” and “dog-tired.” As for the proverb “Every dog has his day,” it was first recorded as an epilogue after the famed Greek playwright Euripides was killed by a pack of dogs in 405 BC.
