A dog, usually a pet dog, often used when speaking to or about a dog in an affectionate or playful way.
From Old English 'docga,' originally a specific type of dog used for hunting but later became a general term for dogs. The diminutive form 'doggy' adds '-y' to create an affectionate, informal variation. The original 'docga' has unclear origins but may relate to size or purpose.
The word 'dog' has uncertain origins—no one is completely sure where 'docga' comes from, which is rare for such a common word! What we do know is that 'doggy' appeared when humans decided they needed a cute, affectionate way to talk to their best friend, which says something about our relationship with dogs.
