Moira is a Greek word meaning fate or destiny — in mythology, the Moirai were the three Fates who spun, measured, and cut the thread of every mortal life. As a pet name it carries genuine weight, but the most likely modern reference point is Moira Rose from Schitt's Creek, Catherine O'Hara's magnificently theatrical character with the wig collection and the mid-Atlantic accent.
The Schitt's Creek Effect
Moira Rose elevated this name from quietly classical to actively funny in the best possible way. A dog named Moira now arrives pre-loaded with comic expectation — especially if the dog has any kind of dramatic energy. The human name Moira sits in a similar cultural position, though the pet version leans harder into the comedy.
Sound and Breed Fit
Moy-rah is pleasingly round in the mouth, works across calling distances, and doesn't blur into other common commands. Suits theatrical, self-possessed dogs such as Standard Poodles, Afghan Hounds, or any cat who ignores you on principle.
The Counter-Reading: Fate Is a Heavy Word
The mythological meaning (fate, the inevitable) is a lot to put on a pet. Owners who know the Greek background sometimes pause at the implication. The Schitt's Creek reading is considerably more cheerful and probably where most modern owners actually live.
