whiskers

Whiskers are long, coarse hairs that protrude from a dog’s muzzle, above the eyes, and around the chin. They are highly sensitive and play a crucial role in a dog’s sensory perception and behavior. Composed of keratin, the same protein that makes up human hair, whiskers are deeply rooted in the skin and are richly supplied with nerves and blood vessels, making them highly sensitive to even the slightest touch.
