What is happening to my BP's nose?

[William S Burrows]

This ^ ^ ^ is a much better picture...it was hard to tell if there was an injury in the other one (like a split on the upper "lip"); this looks like he's just embedded
some substrate...have you tried washing it off gently with a wet Q tip? Not sure he really needs a vet...looks more like a stain, & if you're worried, you could dab
on a little bit of Betadine (povidone iodine) to ward off infection.

Usually easy to handle but is squirmy when I try to pick her up now.
Tried with a damp towel but she wouldn't let me get close enough, will try with a wet Q-tip today after work. Thanks for the advice.
