6. Displaying Relaxed, Fluid Body Language

Physical tension in a dog’s body is the clearest indicator of stress, fear, or uncertainty. According to the American Kennel Club, interpreting canine body language requires looking at the whole picture rather than focusing on a single physical trait. A trusting dog moves with a loose, fluid, and “wiggly” motion.

When assessing your dog’s overall comfort level, look for these specific physical cues:

• Soft ears: Resting in their natural, breed-specific position, rather than pinned tightly back against the skull in fear or held rigidly forward on high alert.
• Open, relaxed mouth: A slightly open mouth with the tongue casually resting or lolling out over the teeth, sometimes resembling a human smile.
• Full-body tail wags: Instead of a stiff, rapid twitch at the very tip of the tail—which often indicates anxiety, frustration, or overstimulation—a trusting dog wags from the base of their spine, often swaying their entire hindquarters side to side.
• The “shake off”: Dogs will often physically shake their bodies to release tension after a stressful or highly stimulating moment. If they shake off and then approach you with a soft posture, they trust you to help them transition back to a calm baseline.
