I noticed that doodle's nose has faded in the center, which I found to be rather odd. I live in the south, and we've been having a mild winter (it's in the 70's 82°! today), so it's not like it's really cold for month's on end. If it is "snownose", or "winter nose", it should go away when the temps warm up...
Have you ever noticed this on your B?
Is this something that happens after a certain age?
Are there any other "conditions" that would cause this?
