| Anxiety Proneness | High |
|---|---|
| Top Triggers | Separation; Unfamiliar people/strangers; Loud noises (thunderstorms, fireworks); Lack of physical/mental stimulation; Changes in routine |
| Separation Anxiety Risk | Very_High |
| Calming Interventions | Desensitization and counter-conditioning; Consistent daily routine; Mental and physical enrichment (puzzle feeders, scent work); Safe space/den creation; Calming supplements/pheromones (L-theanine, DAP) |
| Enrichment Needs | Very_High |
| Cognitive Dysfunction Risk | High |
| Sociability Score | 3/10 |
| Locomotion | Flying trot; Pacing; Galloping; Play bow; Circling |
|---|---|
| Social | Leaning against owner; Mutual grooming; Play solicitation; Following/shadowing; Nuzzling |
| Comfort | Shaking off; Yawning; Stretching; Self-grooming; Circling before lying down |
| Stress/Displacement | Lip licking; Whale eye; Yawning; Panting; Avoidance/turning away |
| Breed-Specific | Herding eye/stalking; Boundary patrolling; Pointing/alert stance; Retrieving |
| Types | Bark (alert); Bark (play); Whine; Growl; Howl |
|---|---|
| Frequency Range | 100-500 |
| Tendency | High |
| Primary Modality | Balanced Vocal/Body |
| Tail/Body Signals | High stiff wag = alert/confident; Low tuck = fearful/submissive; Fast wide wag = excited/happy; Slow wag = uncertain/evaluating |
| Top Problems | Reactivity/Aggression (often fear-based); Excessive barking; Separation anxiety; Destructive behavior (chewing/digging); Leash pulling/lunging |
|---|---|
| Medical Etiology | Sudden aggression/reactivity (pain from hip/elbow dysplasia); Lethargy/behavioral changes (heart disease/cancer); Anxiety/restlessness (bloat/GDV) |
| Fear/Anxiety Etiology | Reactivity to other dogs/strangers (fear-based overreaction); Separation anxiety (vocal and destructive); Fear biting/nipping |
| Frustration Etiology | Destructive chewing/digging (boredom/under-stimulation); Excessive nuisance barking; Leash reactivity (opposition reflex/frustration) |
| Learned Behavior | Demand barking/whining for attention; Jumping on people; Pulling on leash (opposition reflex reinforced by forward movement) |
| Cognitive Dysfunction | Changes in sleep/wake cycle (sundowning); Disorientation/getting stuck in familiar spaces; Pacing/circling/wandering aimlessly; Staring at nothing/barking for no reason |
| AI-Trainable Signals | Tail position/movement (high vs tucked vs flagging); Ear orientation (erect/forward vs flattened/back); Body posture tension (upright/alert vs crouched/submissive); Vocalization pitch changes (high-pitched yip vs low guttural growl); Hackles raised (piloerection) |
|---|---|
| Context-Dependent Vocalizations | High-pitched bark = play/excitement vs deep repetitive bark = alert/warning; Low growl with relaxed body = pleasure/play vs low guttural growl with tense body = warning/guarding; High-pitched whine = seeking attention vs continuous whine = anxiety/discomfort |
| Interspecies Communication | Highly intuitive at reading human body language and emotional states; Uses intense eye gazing to seek connection/affection; Modifies vocalizations (barks, whines, groans, sighs) to express specific needs or emotional states to owners |
