Aggression, hiding, excessive vocalization, or changes in sleep-wake cycles can be primary behavioral disorders, but they can also be symptoms of hyperthyroidism (in cats), brain tumors, cognitive dysfunction (doggie dementia), or chronic pain. A skilled veterinarian must differentiate between a behavior problem and a medical problem—often by combining a physical exam with a detailed ethogram (behavioral repertoire).
Behavioral issues are the leading cause of "relinquishment"—the surrender of pets to shelters. When a veterinarian can address separation anxiety, compulsive behaviors, or inter-pet aggression through a combination of behavioral modification and pharmacology, they aren’t just treating a symptom; they are saving a life by preserving the bond between the owner and the animal. 3.
