Is a dry nose in dogs a sign of illness? Debunking common myths

A common wisdom among dog owners is that a healthy dog ​​should have a cold, moist nose and that a warm or dry nose indicates illness. However, this is not necessarily the case, as various factors can affect the temperature and moisture of a dog's nose.

Understanding nasal moisture and temperature in dogs

The wetness and temperature of a dog's nose can naturally vary throughout the day. Factors such as environmental conditions, hydration, and even the time since the last drink can affect the moisture level of the nose. For example, a dog's nose might be drier if it has been lying in the sun, or it might be warmer if it has been in a heated room.
The dry nose myth probably stems from the fact that dogs' noses are often moist because glandular secretions help them absorb odor chemicals. This moisture can make the nose feel cooler, leading to the belief that a moist nose is a sign of good health. However, the lack of moisture does not necessarily mean that the dog is unwell.

When to worry

While a dry or warm nose alone is not a sign of illness, it should be considered along with other symptoms. Signs of illness in dogs may include lethargy, vomiting, diarrhea, or changes in appetite. If any of these symptoms are accompanied by a dry nose, it is advisable to consult a veterinarian.
