Dogs and humans have enjoyed a long and storied relationship—one that predates Stonehenge, the pyramids of Giza, and even agriculture. Over the millennia, the story of humanity entwined with that of our canine companions to the point that dogs are now a permanent and highly visible fixture within modern culture. This is evident in the many dog-related idioms that pepper the English language.
Here, Stacker has compiled 100 dog-related idioms, some of which many might know and some of which might be more surprising. All words and phrases were collected from The Canine in Conversation, a comprehensive site that lists hundreds of idioms, explains their meaning, and tries to ascertain where each one originated.
From "hair of the dog" to "the dog days of summer," many of the idioms that appear on this list are common expressions frequently found in literature, media, and conversation. Read on to uncover the origins of these popular phrases.
