Frequency Range	100-500
Tendency	Moderate
Primary Modality	Balanced Vocal/Body
Tail/Body Signals	Wagging = happiness/excitement; Tucked = fear/submission; Sweeping/knocking things = extreme joy; Straight out/slightly curved = alert/in motion

Behavior Problems

Top Problems	Separation anxiety; Leash pulling; Destructive chewing; Jumping up; Resource guarding
Medical Etiology	Reluctance to move or irritability (orthopedic pain/hip dysplasia); Lethargy or behavioral changes (hypothyroidism); Restlessness or pacing (gastric dilatation-volvulus)
Fear/Anxiety Etiology	Separation anxiety; Noise phobia (thunderstorms/fireworks); Fear-based reactivity
Frustration Etiology	Destructive chewing (under-stimulation); Leash pulling (frustration to greet); Barrier frustration
Learned Behavior	Jumping on people; Demand pawing or nudging for attention; Counter surfing
Cognitive Dysfunction	Night waking and pacing; Disorientation in familiar spaces; Loss of house training; Altered social interactions

AI Communication Decoding

AI-Trainable Signals	Tail carriage and wag amplitude; Ear position; Body posture tension; Panting rate and facial tension; Vocalization pitch
Context-Dependent Vocalizations	Deep single bark at window = alert vs deep bark during play = excitement; Low grumble when resting = contentment vs low growl with stiff body = warning; Whining at door = need to eliminate vs whining near owner = attention seeking
Interspecies Communication	Uses physical leaning against humans for affection or reassurance; Uses heavy pawing to demand attention; Maintains soft eye contact to monitor owner state
