The third reason why pain or discomfort should always be considered first in a behavior case: pain and fear are neurologically intertwined.
Acute pain and fear share overlapping pathways in the brain, particularly within the amygdala—the center responsible for processing emotional responses. Neurotransmitters like serotonin and noradrenaline influence both behavior and emotional states, which means what we’re seeing on the outside may not have a single root cause.
Pain can shift emotional state. Emotional state can amplify pain.
This is where it gets complex—treating pain alone may not resolve the anticipatory anxiety that develops alongside chronic discomfort. And on the flip side, generalized anxiety can create or worsen pain through chronic muscle tension, fatigue from prolonged “fight or flight,” gastrointestinal upset, poor sleep quality, and increased pain sensitivity.
So what’s the answer?
We don’t choose one or the other—we consider both.
Addressing behavior without evaluating pain risks missing a key piece of the puzzle. And treating pain without supporting the emotional experience may leave dogs stuck in a cycle of stress and discomfort.
Behavior is never just behavior.
