: The scientific study of animal behavior in natural environments, which forms the basis for understanding species-specific needs in domestic or captive settings. The Five Freedoms

As veterinary science extends the lifespan of dogs, we see a rise in CCD. Veterinary behaviorists are pioneering treatments for sundowner syndrome in dogs, using selegiline and environmental modifications (night lights, ramps) to manage the behavioral fallout of aging brains.

| Category | Description | Common Veterinary Examples | |----------|-------------|----------------------------| | | Species-typical behaviors vs. those indicating distress or pathology | Normal: grooming in cats. Abnormal: over-grooming leading to bald spots (psychogenic alopecia). | | Communication | Vocalizations, body language, pheromones | Tail position in dogs; ear flattening in horses; hissing in cats (fear/aggression). | | Social Behavior | Hierarchy, bonding, territoriality | Separation anxiety in dogs; barbering (fur-plucking) in stressed rodents. | | Elimination Behavior | Urination/defecation patterns | Inappropriate urination due to cystitis vs. territorial marking. | | Feeding Behavior | Appetite, foraging, pica | Anorexia from dental pain; eating non-food items (pica) due to anemia or boredom. |
