Sadie

Sadie is a diminutive of Sarah, from the Hebrew Sarah meaning "princess" or "noblewoman." It was a popular standalone name in the 19th century and has enjoyed a strong revival in recent decades. Sadie carries all the warmth of Sarah with an added informality — it's the nickname that stayed, the version people actually called you when they wanted to express genuine fondness.

Sadie holds the #42 spot among US pet names, with nearly 1,800 companions sharing it. The name has a particular Southern warmth to it — easy and sweet and deeply familiar. It suits companions who are both gentle and spirited, affectionate in their own way, and possessed of a quiet but definite personality. Sadie has been a consistent top-50 pet name for over a decade, benefiting from a broader trend of reviving vintage names that feel both classic and fresh.
