Should a healthy dog have a wet nose?

(Q) Is the old wives' tale true, that a healthy dog has a wet nose but a dry nose means he's poorly?

(A) Vet Roberta Baxter says: Mostly, dogs' noses are wet, whether they are healthy or not.

However, there may be some basis to the saying, as dogs with a high temperature often have a dry nose, so a dry nose can be an indication of a dog having a high temperature and being unwell.

Also, some types of skin disease cause the nose to become dry and to crack, so this can also be an indicator of disease.
