Among dog owners, it is generally accepted that gray hair on the animal's face is a sign of aging.
And this is indeed true – in most cases.
As a rule, old age occurs in dogs between the ages of 7 and 10 years, and even earlier in large dogs.
If the pet belongs to a very large breed (that is, if its weight reaches or exceeds 41 kg), then old age for it can occur already at the age of 5 years.
However, small and medium-sized dogs (weighing no more than 50 pounds) are considered senior when they reach 7 years of age, according to the American Veterinary Medical Association.
In addition, the appearance of gray hair is influenced by genes: a number of breeds have a genetic predisposition to this.
But the muzzle can be gray even in one-year-old dogs.
Thus, scientists who conducted a study involving 400 animals came to the conclusion that premature graying is typical for dogs that have a high level of anxiety.
In addition, impulsive dogs, as well as those that are afraid of strangers, animals and noise, are at risk.
Finally, gray hair on the muzzle sometimes tells the dog owner that his pet has health problems.
For example, premature graying of hair is a sign of hypothyroidism.
To be sure that everything is okay with your pet, it makes sense to consult a veterinarian.
