|---|---|
| Frequency Range | 160-2630 |
| Tendency | Moderate |
| Primary Modality | Balanced Vocal/Body |
| Tail/Body Signals | High wag = confident/excited; Low tuck = fearful; Slow wag = uncertain; Helicopter wag = extreme joy |
| Top Problems | Separation anxiety; Territorial aggression/resource guarding; Excessive barking/vocalization; Destructive chewing; Overexcitement/jumping |
|---|---|
| Medical Etiology | House soiling (UTI/kidney issues); Aggression/irritability (pain from arthritis/patellar luxation); Restlessness/pacing (vision loss from cataracts/glaucoma) |
| Fear/Anxiety Etiology | Separation anxiety (destructive behavior/vocalization); Noise phobia (thunderstorms/loud noises); Defensive aggression (fear-based snapping/biting) |
| Frustration Etiology | Destructive chewing (under-stimulation/boredom); Excessive barking (frustration/barrier frustration); Leash reactivity (frustration from inability to greet) |
| Learned Behavior | Demand barking/vocalizing for attention; Jumping on people for greetings; Resource guarding (inadvertently reinforced by taking items away) |
| Cognitive Dysfunction | Pacing or wandering aimlessly at night; Getting stuck in corners; Forgetting previously known cues/house training; Increased anxiety and vocalizing randomly |
| AI-Trainable Signals | Ear orientation (flattened vs alert); Body posture tension (stiffening vs relaxed); Facial muscle tension (bared teeth/lip licking); Tail position (tucked vs high wag); Vocalization pitch changes (whining vs low growl) |
|---|---|
| Context-Dependent Vocalizations | Short bark at door = alert vs short bark during play = excitement; Low growl with toy = play vs low growl with stiff body = warning; Whining at door = potty need vs whining near owner = attention seeking |
| Interspecies Communication | Uses expressive head tilts to investigate new sounds/words; Develops unique snorts and grunts to express mood (e.g., brat snort); Uses intense eye contact to demand attention or resources |
