What are Dogs Whiskers for?

Whiskers, or vibrissae, are long, coarse hairs protruding from a dog’s muzzle, jaw and above its eyes. But what are these strange hair-like projections for? As a caregiver, you may have wondered about the purpose of your furry friend’s whiskers. They might seem like just another cute feature of your pet, but they serve some critical functions.

1. Sensory Perception

You’ve probably noticed how your dog’s whiskers twitch when they’re in a new environment or sniffing out something interesting. The whiskers provide a wealth of information about a dog’s surroundings, acting as an extension of their senses.

• Whiskers contain highly sensitive nerve endings which send signals to the dog’s brain.
• They help your dog navigate in the dark by detecting changes in air currents.
• Whiskers located above the eyes, known as ‘supraorbital whiskers’, can trigger a protective blink reflex if they sense an impending threat.

2. Emotion Expression

Just as dogs use their tails to express their emotions, their whiskers also play a part in their emotional display. Observing your dog’s whisker position can give you insights into their emotional state.

1. Forward-facing whiskers usually indicate alertness or excitement.
2. Relaxed whiskers are a sign of contentment.
3. Pulled-back whiskers might suggest fear or aggression.

3. Hunting and Prey Detection

In the wild, dogs use their whiskers as a hunting tool.

• They can sense the movement of prey through air disturbances.
• Whiskers can even detect slight changes in temperature, helping dogs identify warm-blooded prey.

4. Communication

Dogs are social animals. Their whiskers help them communicate with other dogs and animals.

• Positioning of the whiskers can signal submission or dominance.
• Whiskers can indicate the dog’s intention, whether friendly or threatening.

5. Protection

Lastly, whiskers serve as a protective mechanism for dogs.

• They act as an early warning system, helping dogs avoid potential threats.
• The whiskers above the eyes protect the eyes from debris and low-hanging objects.
