In conventional veterinary medicine, the five classic vital signs are temperature, pulse, respiration, pain, and blood pressure. Leading institutions are now advocating for a sixth: behavior .

Veterinarians focused on physiology, pathology, and pharmacology—the tangible mechanics of the animal body. Ethologists and behaviorists focused on instinct, learning, and social dynamics—the intangible software running on the biological hardware.
