Think about it. Its the exact same reason why cats have
whiskers! If a dog was to climb into a pitch black hole, the
whiskers will tell them if or how close they are to the walls.

Whiskers, or vibrissae, are long, coarse hairs protruding from a dog's muzzle, jaw and above its eyes.

The follicles at the base of these hairs are packed with nerves that send sensory messages to a dog's brain.

Being able to feel vibrations in the air also helps dogs sense approaching dangers.
