💡 : If you're interested in the "medical" side of behavior, look into Veterinary Behaviorist programs. These professionals are vets who specialize in the mental health of animals. To help you further, Advice on applying to Vet School ?

Veterinary science has traditionally prioritized physiological parameters (e.g., weight, temperature, blood work) over behavioral metrics for pain assessment. However, in social species, pain is not an isolated individual experience; it alters social signaling, affiliation, and conflict resolution. Captive environments amplify this effect due to limited escape opportunities and fixed social groupings. Grooming in macaques is a barometer of social health—reduced grooming correlates with increased cortisol and disease susceptibility. Yet, no standardized veterinary protocol currently screens for social sequelae of mild chronic pain. This paper bridges ethology and clinical practice by asking: Can grooming patterns serve as an early, non-invasive diagnostic tool for chronic pain in captive non-human primates?

Just as human psychiatry has advanced, veterinary behavioral medicine now uses pharmaceuticals to treat profound mental suffering. Dogs with severe separation anxiety, cats with compulsive disorders (like excessive grooming leading to self-mutilation), and birds with stereotypic pacing are not "misbehaving." They are often experiencing neurochemical imbalances.
