I know that dog's noses are supposed to always be wet, and that the dog is probably sick if it's not, but I have a few questions about it.
1. Why? Whay are dog noses wet, what makes them that way?
2. Is it all dogs that have wet noses (because my friend's dog doesn't have one)?
3. What about cats? Are they the same way, or not?
I would really appreciate it if anyone could answer one or more of my questions. Thanks
