| Separation Anxiety Risk | High |
| Calming Interventions | Puzzle toys/mental stimulation; Consistent routine; Desensitization training; Regular vigorous exercise; Calming supplements (e.g., L-theanine, CBD) |
| Enrichment Needs | Very_High |
| Cognitive Dysfunction Risk | Moderate |
| Sociability Score | 4/10 |
| Locomotion | Trotting gait; Herding circling; Play bow; Pouncing; Zoomies/FRAPs |
|---|---|
| Social | Leaning against owner; Velcro dog/following; Play solicitation; Submissive rolling; Mutual grooming |
| Comfort | Circling before lying; Stretching; Yawning; Self-grooming; Shaking off |
| Stress/Displacement | Lip licking; Whale eye; Paw lifting; Excessive yawning; Sniffing the ground |
| Breed-Specific | Herding eye; Nipping at heels; Guarding stance; Wiggle butt |
| Types | Bark (alert); Bark (play); Whine; Growl; Grunt/Groan |
|---|---|
| Frequency Range | 400-1000 |
| Tendency | High |
| Primary Modality | Balanced Vocal/Body |
| Tail/Body Signals | Full body wiggle (wiggle butt) = extreme joy; Nub wag = excited/happy; Tucked nub = fearful/submissive; Stiff nub = alert/guarding |
| Top Problems | Herding/nipping inappropriate targets; Destructive behavior; Excessive barking; Separation anxiety; Leash reactivity |
|---|---|
| Medical Etiology | Startle-induced aggression (vision/hearing deficits); Sudden behavioral changes (epilepsy); Neurological symptoms (MDR1 gene drug sensitivity) |
| Fear/Anxiety Etiology | Noise phobia (thunderstorms/fireworks); Stranger reactivity (fear-based); Separation anxiety |
| Frustration Etiology | Destructive chewing/digging (under-stimulation); Fence running (barrier frustration); Excessive barking (boredom) |
| Learned Behavior | Demand barking; Jumping on people; Nipping at heels for attention |
| Cognitive Dysfunction | Night waking/pacing; Disorientation in familiar environments; Loss of house training; Getting stuck in corners |
| AI-Trainable Signals | Ear orientation; Body posture tension; Hind-end wiggle; Vocalization pitch changes; Intense eye contact |
|---|---|
| Context-Dependent Vocalizations | Sharp bark during herding = excitement vs sharp bark at door = alarm; Low growl during tug = play vs low growl with stiff body = warning |
| Interspecies Communication | Uses intense eye contact to direct owner attention; Leans heavily against owner legs for reassurance; Uses grumbling vocalizations to express opinions |
