Body stiffness is a visible increase in muscle tension that may signal uncertainty, high focus, discomfort, conflict, or preparation for action.
Common Signs
- Rigid Posture
- Closed Mouth
- Fixed Stare
- Frozen Movement
- Weight Shift Forward
- Tail Changes
Important Distinction
Tension matters more than a single tail or ear position. A wagging tail does not cancel out a rigid body, hard stare, or closed mouth.
What Can Help
Stop forward pressure, create space, change the setup, and watch whether the dog’s movement, face, and breathing soften once the concern is reduced.
When To Get Professional Help
Professional assessment is important when stiffness appears before growling, lunging, snapping, guarding, or handling conflict.
