- **Cognitive Dysfunction Risk**: High

## Behavior Problems (Six-Etiology Classification)
- **Top Problems**: Separation anxiety; Leash pulling; Destructive chewing; Excessive vocalization/demand barking; Jumping up
- **Medical Etiology**: Lethargy/behavior change (Histiocytic sarcoma/cancer); Irritability/aggression (Hip/elbow dysplasia pain); Restlessness (Gastric Dilatation-Volvulus/Bloat)
- **Fear/Anxiety Etiology**: Separation anxiety (hyper-attachment); Noise phobia (thunderstorms/fireworks); Stranger anxiety (aloofness/fear-based)
- **Frustration Etiology**: Destructive chewing (under-stimulation); Leash pulling/reactivity (frustration); Excessive vocalization (boredom)

## AI Communication Decoding
- **AI-Trainable Signals**: Tail position/movement; Ear orientation (forward vs back); Body posture tension; Vocalization pitch changes; Facial muscle tension (jowls)
- **Context-Dependent Vocalizations**: High-pitched whine for attention vs low whine for anxiety; Awooo-growl for greeting vs low growl for warning; Short bark for play vs deep bark for alerting
