"What is your pet's name?"
Translation:¿Cómo se llama tu mascota?
The literal translation of "¿Cómo se llama?" is "What do you call yourself?" which is fine when asking people what their names are... but a pet can't call itself anything, so I wrote, "¿Cuál es el nombre de tu mascota?" and it was accepted.
Would a native Spanish speaker make that distinction, though? Or is "¿Cómo se llama?" used universally, regardless of whether it's a pet or even an inanimate object (such as a doll)?
No, nothing is missing. "Llamarse" is a verb used to tell or find out a name.
