As a pet parent with an adopted dog, you might not know your dog's exact age. And now his hair, especially around his muzzle, is turning gray. Does a gray muzzle mean he's becoming a senior dog? Or is it a sign that something is wrong?
Gray hair on a dog's face and around his muzzle is a natural occurrence as he ages — just like turning gray is a natural occurrence for humans. Because dogs age faster than humans, they turn gray sooner than their pet parents. And just like humans, some dogs turn gray much earlier in life than others.
Behavior and Health Link
While typically a sign of an aging dog, a gray muzzle can also be found in dogs as young as one year old. A study of 400 dogs, published in Applied Animal Behaviour Science, discovered that dogs that experience high levels of anxiety, are impulsive or have fearful responses to strange people, animals and noises are linked to premature graying — not much different to when you hear people say things like, "you're the reason I am going gray."
A graying muzzle may also indicate a health issue. For instance, premature graying of the muzzle is one sign your dog might have hypothyroidism. Because it could be health-related, you should consult with your veterinarian if your dog starts graying.
