Meaning & Story
From the English surname Henderson, meaning son of Henry — Henry itself from the Germanic Heimrich meaning home ruler or estate master.
Henderson is a surname-name with the kind of grounded, trustworthy quality you want in both a best friend and a faithful dog. It has the air of someone who shows up on time, keeps his word, and will absolutely be there when things go sideways. It is slightly more distinguished than plain Henry, with the -son suffix giving it a solid, old-fashioned American family name quality. Dogs named Henderson tend to be the steadfast, reliable type — the ones who wait by the door and never need to be asked twice.
