Over the last couple of days, I have noticed that my snake has what appears to be a dry nose. It is hard to describe, and I'll maybe post a pic when I get home, but it looks like what would and could be described as dry skin...if it were on a human. White and flaky? Has anybody ever seen this on a snake before? Any ideas on what it could be? My snake is off feed, and is maybe getting to the point of concern...going on four months now..but there is a long story behind that. He is healthy and active otherwise. Just want to get some kind of feedback if anybody here has ever seen anything like this.
