Matty is an interesting choice for a female pet; it's typically a masculine nickname (diminutive of Matthew), but used here with a feminine gender preference in registry data. That crossover signals a deliberate subversion: the owner wanted something grounded and no-nonsense rather than traditionally feminine, while keeping the warm IE ending.
Gender-Neutral Nickname Aesthetic
Names like Matty, Charley, Billie, and Frankie have carved out space as gender-neutral-leaning nicknames that work for female pets well. Australian Shepherds and working-dog breeds suit this register, dogs with practical energy that don't need feminized names to communicate personality.
Human-Pet Crossover
Matty Healy of The 1975 gave the name a pop-cultural refresh in the 2020s, making it feel current rather than retro on younger owners. The human name Matthew is the formal source, but Matty stands alone without ceremony. See pet names for related options.
Counter-Reading: Gender Confusion at the Vet
Matty on a female dog will occasionally generate a misgendering at the vet's office. If you don't mind the correction, Matty is a strong, characterful name. If you want something equally grounded without the pronoun confusion, Macy sits in a similar register.
