rwbeagles:
can you scale it off with your fingernail? Fronts only or backs, too? If so I'd vote that it's saliva build up from foot licking.
The color is a little less that a centimeter on front and back toenails... almost on every toe... it doesn't scrape off at all... there is nothing to scrape off... its like it is part of the nail, same texture everything, it isn't uplifted at all...
saliva build up?? is that bad? what do you do for it?
