Airplane ears, rotated sideways and back, appear with tension, wariness, or displeasure and serve as a lower-intensity warning that comes before puffing.
Read the escalation: sideways ears mean unease, fully flattened-back ears edge toward fear or pre-attack, and dilated pupils raise the conflict risk further.
Common triggers are strange noises, forced handling, clinic settings, and approaching animals; once identified, remove the stressor instead of pushing the interaction.
If airplane ears persist without an obvious trigger, or come with ear scratching and head shaking, get a vet check for ear infection or chronic pain.
