Sonny

Sonny is an English nickname derived from "son," used as a term of endearment for a boy or young man, with roots in the affectionate address that parents and elders have used for generations. It carries warmth and familiarity without pretension. Pet owners who choose Sonny tend to see their companion as a beloved family member first — easygoing, sunny-natured, and completely at home wherever you are.

Sonny holds #221 on the pet name charts and has the kind of breezy, good-natured energy that makes it universally appealing. Its meaning as a term of endearment is essentially built into the name itself — calling your companion Sonny is already an act of love. The name suits a cheerful, sociable pet who gets along with everyone and seems to carry a little bit of sunshine in their personality. It's comfortable and familiar, like a well-worn sweater, and that's exactly what makes it so endearing.
