While often dismissed as temperamental, sudden aggression in a feline is frequently linked to hyperthyroidism, dental disease, or osteoarthritis. A cat that strikes out when touched near the lower back may not be angry; it may be suffering from a painful inflamed bladder (cystitis).
For decades, veterinary medicine focused almost exclusively on the physical health of animals—vaccinations, surgeries, and the eradication of parasites. However, as our understanding of the animal kingdom has evolved, so too has the realization that mental and physical health are inextricably linked. Today, the intersection of represents one of the most dynamic and essential fields in modern animal care. The Evolution of Clinical Ethology While often dismissed as temperamental, sudden aggression in
Highly heritable and functionally relevant breed differences in dog behavior Authors: Morrill, K., et al. (2022) - Science . Relevance: This is a landmark study that analyzed the genomes and behavior of over 2,000 dogs. It challenges the traditional assumptions that breed strictly determines behavior (e.g., "all Pit Bulls are aggressive"). It is crucial for veterinarians when advising clients about breed selection and understanding genetic predispositions versus environmental influences. However, as our understanding of the animal kingdom
One of the most tragic realities of veterinary medicine is the rate of euthanasia due to untreatable behavioral problems. According to studies from leading veterinary colleges, behavioral issues—not infectious diseases or organ failure—are the leading cause of death for dogs under three years of age. Aggression, severe anxiety, and destructive behaviors account for approximately 10-15% of all canine euthanasias. (2022) - Science
In veterinary medicine, behavior is often the first—and sometimes only—indicator of a health issue. Because animals cannot verbally communicate pain, they express internal distress through behavioral changes
