dogs: sweaty nose

I have recently read in Topnews.in that the wet nos of a dog improves the sniffing ability contrary to the belief that it is a sign of good health.

If you'll notice it's really the only part of a dog's body that sweats :) It's their ventilation or something - if it's hot then it sweats (just like people's skin) and if it's cold then it doesn't...or at least it shouldn't :) can you type with long nails?

In fact not only dogs, but also cats have sweaty nose. I don't really understand why they have sweaty nose. But I know sweaty noses mean that they are healthy:) I love China

Dogs have sweat glands in their noses.. cold nose means that the dog is in good shape/healthy and when it's hot then probably the dog has fever or the dog isn't feeling well.. but generally dog's sweat glands are to be found between the pads on its paws.. well, i'm not so sure about the info i've got so i guess you need to make a thorough research if you really wanted to find out why..
