- **CHIC Required Tests**: Hip Evaluation; Elbow Evaluation; Cardiac Exam; Ophthalmologist Evaluation; Thyroid Evaluation
- **Recommended DNA Tests**: Canine Multifocal Retinopathy (CMR1); Degenerative Myelopathy (DM); Dominant PRA (PRA-D)

## Behavioral Ethogram
- **Locomotion**: Heavy trotting; Sudden bursts of speed; Stiff-legged approach; Play bow; Pacing
- **Social**: Leaning heavily against owner; Sitting on feet; Gentle nudging; Calm observation; Mutual grooming
- **Comfort**: Deep sighing; Stretching; Circling before lying down; Yawning; Shaking off
- **Stress/Displacement**: Lip licking; Whale eye; Turning head away; Panting; Freezing
- **Breed-Specific**: Pinning/holding without biting; Silent guarding; Body blocking; Stealthy approach

## Vocalization Baseline
- **Types**: Growl (warning); Bark (alert); Snort/Grunt; Sigh
- **Frequency Range**: 100-400
- **Tendency**: Low
- **Primary Modality**: Primarily Body Language
- **Tail Signals**: High stiff wag = alert/assessing threat; Relaxed low carriage = calm/content; Tucked tail = fearful/stressed; Slow wag = greeting

## Emotional Wellbeing
- **Anxiety Proneness**: Low
- **Top Triggers**: Separation; Boredom; Strangers/New people; Unfamiliar environments; Lack of leadership/structure

- **Fear/Anxiety Etiology**: Stranger aggression (fear-based); Separation anxiety; Noise phobia
- **Frustration Etiology**: Destructive behavior (boredom/under-stimulation); Barrier frustration (fence running); Leash pulling

## 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 with relaxed body = play vs low growl with stiff body = warning; Short bark = alert vs continuous barking = distress
- **Interspecies Communication**: Uses body blocking to guard/protect; Leans against owner for comfort/reassurance; Intense staring to communicate needs
