If you say every dog has its day, you mean that everyone will be successful or lucky at some time in their life. Former England player Davies said: `Every dog has his day, although the way I kicked throughout the game, who would have thought that drop goal would even reach the posts?' `I don't have any money to fight him,' he said. `But every dog has its day and I have lots of patience.' Note: This expression is sometimes used to encourage someone at a time when they are not having any success or luck. Note: This proverb has been known in English since at least the 16th century. Shakespeare quotes it in `Hamlet': `Let Hercules himself do what he may, The cat will mew and dog will have his day.' (Act 5, Scene 1).
