## Puppy/Kitten Development
- **Neonatal Weight**: 141–226 g

## Adult Preventive Care
- **Exercise Needs**: Moderate
- **Grooming**: Moderate
- **Annual Exam Focus**: Cardiac auscultation; Eye exam; Patellar evaluation
- **Routine Care**: Senior Cavaliers require biannual vet visits with blood work, joint mobility supplements for arthritis, moderate exercise, and careful monitoring of advanced Mitral Valve Disease (MVD).

## Health Predispositions
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Mitral Valve Disease | Adult | High | No | No |
| Syringomyelia | Adult | High | No | No |
| Patellar Luxation | Juvenile | High | No | No |
| Hip Dysplasia | Adult | High | Yes | Yes |
| Eye Conditions | Adult | High | Yes | Yes |
| Cardiac Disease | Adult | High | Yes | Yes |

## Obesity Management
- **Risk Level**: High
- **Ideal BCS**: 5/9
- **Visual Cues**: Ribs easily palpable with slight fat covering; slight hourglass waist narrowing in front of hind legs when viewed from above; abdominal tuck visible from side.
- **Daily Activity Target**: 40 minutes
- **Caloric Formula**: {"daily_kcal_per_kg": 50, "RER_factor": 70, "activity_multiplier": 1.2}

## Breeding & Genetics
- **Litter Size**: 3–5
- **Dystocia Risk**: Low
- **CHIC Required Tests**: Hip Dysplasia; Cardiac Exam; Patellar Luxation; Eye Exam
- **Recommended DNA Tests**: Episodic Falling Syndrome (EFS); Dry Eye Curly Coat Syndrome (CKCSID); Degenerative Myelopathy (DM); Muscular Dystrophy (DMD); CDDY/IVDD

## Behavioral Ethogram
- **Locomotion**: Trotting gait; Short bursts of speed; Lap seeking; Following owner closely
- **Social**: Leaning against owner; Gentle eye contact; Seeking physical contact/cuddling; Play solicitation
- **Comfort**: Yawning; Sniffing the ground; Licking nose; Turning head away
- **Stress/Displacement**: Lip licking; Yawning; Sniffing the ground; Turning head away; Averting gaze
- **Breed-Specific**: Obsessive fly catching; Paedomorphic/juvenile behaviors; High empathy/attunement to owner

## Vocalization Baseline
- **Types**: Bark (alert); Bark (attention-seeking); Whine; Growl (play)
- **Frequency Range**: 500-2000
- **Tendency**: Moderate
- **Primary Modality**: Balanced Vocal/Body
- **Tail Signals**: Fast vertical wag = excitement; Slow wag with relaxed body = contentment; Tucked tail = fear/anxiety

## Emotional Wellbeing
- **Anxiety Proneness**: High
- **Top Triggers**: Separation; Loud noises; Unfamiliar environments; Unfamiliar people or animals; Confinement without preparation
- **Separation Anxiety Risk**: Very_High
- **Calming Interventions**: Gradual desensitization; Decouple departure cues; High-value food enrichment/puzzle feeders; Positive crate training; Group training classes/socialization
- **Cognitive Dysfunction Risk**: High

## Behavior Problems (Six-Etiology Classification)
- **Top Problems**: Separation anxiety; Excessive barking; Resource guarding; Attention-seeking behavior; Fearfulness/timidity
- **Medical Etiology**: Air scratching/vocalization (Syringomyelia/Chiari-like malformation); Sudden aggression/irritability (pain from hip dysplasia/luxating patella); House soiling (UTI/Cognitive Dysfunction)
- **Fear/Anxiety Etiology**: Separation anxiety (panic when left alone); Noise phobia/fearfulness of loud noises; Timidity/fear of unfamiliar environments or larger dogs
- **Frustration Etiology**: Excessive barking (boredom/under-stimulation); Destructive chewing (boredom/stress); Attention-seeking behaviors (pawing/nudging when ignored)

## AI Communication Decoding
- **AI-Trainable Signals**: Tail position/movement (high/stiff vs low/tucked); Ear orientation (perked up vs flattened back); Eye contact/shape (soft eyes vs hard stare/whale eye); Facial muscle tension (relaxed mouth vs lip licking/yawning); Body posture (play bow vs tensing up/backing away)
- **Context-Dependent Vocalizations**: Frantic barking when alone = separation anxiety vs barking at triggers = alert/fear; Growling when approached with resource = guarding vs growling during play = excitement; Whining/crying = attention-seeking vs whining/crying = pain/distress (e.g., from Syringomyelia)
- **Interspecies Communication**: Highly attuned to human emotional tone and easily shut down by harsh voices; Uses attention-seeking physical contact (pawing/nudging) to initiate interaction; Relies heavily on eye contact and soft gazes to bond with owners
