Stress may give your pooch a `salt-and-pepper’ look, say scientists who found that just like us, our canine friends too are susceptible to hair greying due to anxiety .
Researchers from Northern Illinois University (NIU) in the US examined 400 dogs. Results showed that dogs between 1-4 years of age exhibiting higher owner-reported signs of anxiety showed a greater extent of premature muzzle greying than their less anxious peers.
Increased muzzle greyness also was related to owner-reported symptoms of impulsivity in the dogs.
Female dogs showed higher levels of greyness than male dogs but dog size, spay neuter status and the presence of medical problems did not significantly predict the extent of muzzle greyness.
