## Behavioral Ethogram
- **Locomotion**: Smooth trotting gait; Play bow; Zoomies/FRAPs; Bounding/hopping

- **Frustration Etiology**: Destructive chewing (under-stimulation); Excessive barking (boredom); Pacing

## AI Communication Decoding
- **AI-Trainable Signals**: Tail position/movement; Ear orientation; Body posture tension; Vocalization pitch changes; Facial muscle tension
- **Context-Dependent Vocalizations**: Low growl to communicate needs vs low growl as warning; Short bark during play vs short bark for attention
