pricked up one's ears

Became sharply alert

To prick up one's ears is to suddenly become alert and attentive, like a dog or horse whose ears rise at an interesting sound.

The phrase describes that moment when something catches your attention and you start listening more carefully: She pricked up her ears when she heard her name mentioned in the next room.
