5-year-old neutered male Labrador Retriever. History: Sudden growling when touched on the back. Previously friendly. Workup: Orthopedic exam showed mild discomfort on spinal palpation. Radiographs revealed mild lumbosacral osteoarthritis. Outcome: After treatment with NSAIDs and environmental modification (ramps, soft bedding), aggression resolved. This case illustrates that “behavioral” problems often have medical roots.

Behavioral signs of fear (e.g., trembling, tail tucking, piloerection, avoidance, freezing, or escape attempts) indicate activation of the sympathetic nervous system and hypothalamic-pituitary-adrenal (HPA) axis. Chronic stress can cause immunosuppression, gastrointestinal disturbances, and stereotypies (repetitive, invariant behaviors such as pacing, crib-biting in horses, or over-grooming in cats). Recognizing stress behaviors allows the clinician to modify handling techniques and recommend environmental enrichment. Zooskool - C700 - Dog Show Ayumi Thatty.avi 2 --39-LINK--39-
