puppy-dog

The compound "puppy-dog" is a reduplicative or emphatic formation, combining two synonyms for emphasis and affection. The word "puppy" itself entered English from the Old French poupée, meaning 'doll' or 'toy', reflecting the small, plaything-like nature of a young canine. "Dog" is a native English word of ancient but obscure origin. When paired, "puppy-dog" leverages the inherent cuteness and familiarity of "puppy" and reinforces it with the generic term "dog," creating a term often used in child-directed speech or affectionate contexts to denote a dog, particularly one perceived as charming, harmless, or youthful. The logic is one of affectionate specification, using near-synonyms to soften and endear.
