- **Annual Exam Focus**: Breathing/Airway evaluation; Eye examination; Knee/Joint evaluation (Patellas); Weight/Body Condition Score
- **Routine Care**: Monitor for eye diseases (cataracts, glaucoma), manage weight to prevent worsening of breathing/joint issues, and provide joint support for arthritis secondary to patellar luxation.

- **Dystocia Risk**: High
- **CHIC Required Tests**: ACVO Eye Exam; Patellar Luxation; Congenital Deafness
- **Recommended DNA Tests**: Early-onset Hereditary Juvenile Cataracts (HSF4 mutation)

## Behavioral Ethogram
- **Locomotion**: Trotting gait; Play bow; Pouncing; Zoomies/FRAPs

- **Comfort**: Circling before lying; Stretching; Yawning; Self-grooming; Shaking off
- **Stress/Displacement**: Lip licking; Whale eye; Paw lifting; Excessive yawning; Avoidance/turning away
- **Breed-Specific**: Alert expression; Companion-focused attention; Pointing stance

## Vocalization Baseline
- **Types**: Bark (alert); Bark (play); Whine; Growl; Howl; Bay
- **Frequency Range**: 160-2630
- **Tendency**: Moderate
- **Primary Modality**: Balanced Vocal/Body
- **Tail Signals**: High wag = confident/excited; Low tuck = fearful; Slow wag = uncertain; Helicopter wag = extreme joy

## Emotional Wellbeing
- **Anxiety Proneness**: Moderate
- **Top Triggers**: Separation; Thunderstorms/Noise; Strangers; Confinement; Travel
- **Separation Anxiety Risk**: High
- **Calming Interventions**: Puzzle toys/mental stimulation; DAP pheromone diffuser; Compression garment (ThunderShirt); Desensitization training; Regular exercise routine
- **Cognitive Dysfunction Risk**: Moderate

## Behavior Problems (Six-Etiology Classification)
- **Top Problems**: Separation anxiety; Territorial aggression/resource guarding; Excessive barking/vocalization; Destructive chewing; Overexcitement/jumping
- **Medical Etiology**: House soiling (UTI/kidney issues); Aggression/irritability (pain from arthritis/patellar luxation); Restlessness/pacing (vision loss from cataracts/glaucoma)
- **Fear/Anxiety Etiology**: Separation anxiety (destructive behavior/vocalization); Noise phobia (thunderstorms/loud noises); Defensive aggression (fear-based snapping/biting)
- **Frustration Etiology**: Destructive chewing (under-stimulation/boredom); Excessive barking (frustration/barrier frustration); Leash reactivity (frustration from inability to greet)

## AI Communication Decoding
- **AI-Trainable Signals**: Ear orientation (flattened vs alert); Body posture tension (stiffening vs relaxed); Facial muscle tension (bared teeth/lip licking); Tail position (tucked vs high wag); Vocalization pitch changes (whining vs low growl)
- **Context-Dependent Vocalizations**: Short bark at door = alert vs short bark during play = excitement; Low growl with toy = play vs low growl with stiff body = warning; Whining at door = potty need vs whining near owner = attention seeking
- **Interspecies Communication**: Uses expressive head tilts to investigate new sounds/words; Develops unique snorts and grunts to express mood (e.g., brat snort); Uses intense eye contact to demand attention or resources
