Casey Dog Name Meaning, Origin & History

What does the dog name Casey mean?

The sourced meaning of Casey is “descendant of CATHASACH”. This is an etymological meaning: it describes the older linguistic root or naming element behind the name, not a prediction about the personality of a dog who carries it. That distinction matters because names often travel through languages and centuries before reaching their modern form. For dog naming, the meaning can add a story to the choice while the actual fit still comes down to the sound of Casey and how naturally it suits the animal.
