Question:
Why are Dog's noses wet? Are all dogs noses always wet? Is there a health concern in any case?



Replies:
Eric,

Dog's noses are wet because there is a specific duct which drains fluid from the eyes ( tears) directly towards the nose. You may know that a dog's sense of smell is far stronger than that of a human, and their sense of smell serves them in both locating food and deciding if a food is spoiled or not (sometimes hunger overwhelms the safety issue, so it is not a sure protection). A dog's wet nose is the norm and not something to be concerned about.

Occasionally, the duct draining the fluid from the eyes towards the nose becomes clogged; you may have seen especially white dogs, e.g. poodles, which can develop a reddened area around the eyes from inflammation related to this clogging. Generally, the situation will correct itself, even though it is quite unsightly.

Thanks for using NEWTON!
