Can Dogs Lose Their Whiskers?

    Most people think of whiskers as the sole providence of cats. They're not. Dogs have whiskers, too, and they're just as important to them as they are to cats. Through daily wear, injury or disease, dogs can loose their whiskers, though. They'll grow back, but the transition isn't always easy.

    Whiskers aren't just hairs; they're sensory organs that help guide your pets. Your dog's whiskers are kind of like antennae -- they help her see up close and in the dark, where her eyesight isn't as good. It's not the whisker itself that feels, but the nerves in the hair follicle, which is rooted much deeper than normal hairs. They function via vibration, which is why they're called vibrissae. A touch or even a soft wind is enough to trigger them. Incidentally, the long hairs on the top of your dog's eyes and sides of his face are also vibrissae.

    Whiskers splinter, break or fall out on a semi-regular basis, but -- barring a fight with another dog -- your canine friend will never lose all her whiskers at once unless something's wrong. One possibility is alopecia, the technical word for hair loss. It's a disorder that affects your dog's skin, endocrine and immune systems. It can be either gradual or acute and varies greatly in severity. One possible cause is mange, which is technically a mite infestation. Bacterial infections, ringworm and immune diseases are other possibilities. It's noteworthy that alopecia usually affects all hairs, not just vibrassae.

    Discovering the cause of her alopecia is the first step to helping your dog regrow her hair and vibrassae. A host of pills, shots and topical treatments may be in order. Hair regrowth can be slow, and whisker regrowth can be even slower. Even after your dog's back to normal, check her regularly to catch recurrent or new problems as early as possible. Early detection and early treatment can save you and your dog a lot of stress.

    When your dog loses her whiskers, she probably feels confused and discombobulated. These sensors are how she interacts with the world, so it's almost like how you'd feel after losing, say, your fingertips. As such, it's important to treat your dog gently if she lost a lot of whiskers at once. Also, never, ever trim your dog's whiskers. It provokes unnecessary stress. Yes, her whiskers will grow back, but the lack of stimuli can negatively affect her mood and disposition.
