|---|---|
| Social | Leaning on owner; Licking owner's face/body; Exaggerated greeting upon return; Play bow |

|---|---|
| Frequency Range | 150-500 |
| Tendency | Low |
| Primary Modality | Primarily Body Language |
| Tail/Body Signals | Relaxed/neutral = calm; Slow wag = contentment; Rapid wag with body wiggle = happiness; Tucked tail = fear/submission |
| Top Problems | Destructive chewing; Stubbornness/selective deafness; Resource guarding (toys/food/attention); Dog-directed aggression; Attention-seeking behaviors (barking/nipping) |
|---|---|
| Medical Etiology | Sudden aggression/behavior changes (pain/illness); Lethargy/activity changes (poor diet/obesity); Restlessness/pacing (Canine Cognitive Dysfunction) |
| Fear/Anxiety Etiology | Phobias of household objects (vacuums/mops/bags); Aggression toward other dogs (fear/defensive); Sudden behavioral changes/seeking corners |
| Frustration Etiology | Destructive chewing (boredom/lack of attention); Attention-seeking barking/nipping; Sulking/staring at walls (when feeling "hard done by") |
| Learned Behavior | Demand barking/attention-seeking; Guarding toys/sofa (if previously reinforced); Jumping up for play |
| Cognitive Dysfunction | Aimless pacing/staring at walls; Loss of housetraining (accidents indoors); Changes in sleep patterns (restless nights/night waking); Disorientation/forgetting routines |
| AI-Trainable Signals | Tail position/movement (tucked/clamped vs wagging); Ear orientation (laid back vs relaxed); Body posture tension (lowered head/stiff body vs relaxed); Vocalization pitch/type (growl vs bark vs whine); Facial muscle tension (wrinkled muzzle/lip licking) |
|---|---|
| Context-Dependent Vocalizations | Growl during play (invitation) vs growl with stiff body/wrinkled muzzle (warning/aggression); Barking/jumping (stirring up/play) vs barking at objects (fear/phobia); "Piggy noises"/snorting (normal breathing) vs increased panting/snorting (stress/overheating) |
| Interspecies Communication | Uses "selective deafness" when unmotivated; Turns sideways to human to calm them down/show non-aggression; Shows belly as sign of absolute trust/submission |
