Dogs noses?

how come my dogs noses are sometimes cold and wet, and other times they are all dry, like sandpaper almost. lol. usually they are dry at nite. my friend said it was because they were tired?? is it?? :P

the reason why dogs noses are wet is they like to lick them.

It's caused by the pores in their nose and the dogs licking it constantly

I am pretty sure it tells there body temp?

There really is no reason, has to do with humitity, if they just drank water, etc...it has NOTHING to do with illness or body temperature...it just is...

p

Its normal. It just pretty much means different moods and activities they do, the different between a dry and wet nose.

its because they are like thirsty so make sure your dog has water when their noses get like that
