Dogs have whiskers for a variety of reasons, including:To help them navigate in the dark,To feel objects in their environment,To maintain balance.
Whiskers help dogs to navigate in the dark by detecting even the slightest changes in air currents. This allows them to feel their way around and avoid obstacles.
Whiskers are also very sensitive to touch, and they can help dogs to feel objects in their environment, even if they cannot see them.
Whiskers can also be used by dogs to communicate with each other. For example, when two dogs meet, they will often touch their whiskers together.
Whiskers also help dogs to maintain their balance. When a dog moves, their whiskers brush against objects in their environment.
Finally, whiskers can also help to protect dogs' eyes. When a dog is walking, their whiskers can help to brush away dust and debris that could get into their eyes.
