Mallory is a Norman French surname meaning "unlucky" or "ill-omened," from malheure — bad luck. The irony of giving an adored pet a name that means ill-fated is not lost on owners who choose it. That self-aware irony is part of the appeal, particularly among the group that grew up watching Family Ties or Natural Born Killers.
Pop-Culture Reading: Family Ties
Mallory Keaton on Family Ties (1982–1989) gave the name its mainstream American moment — a popular, fashion-conscious teenager played by Justine Bateman. That character is now distinctly 1980s, which makes Mallory a retro-cool choice for owners with a Gen X aesthetic. Cocker spaniels and shih tzus carry the name's slightly glamorous, slightly ditzy energy well.
Human-Pet Crossover
The human name Mallory peaked in the 1980s and 1990s and is now in a retro holding pattern. Giving a pet this name in 2025 is a deliberate vintage signal — not ironic exactly, but knowingly nostalgic.
