My het Snow shed yesterday and I cleaned her tub only to find that there's a wound on the top of her snout.

One of the larger plate-like scales is flipped up and I can see 'meat' underneath.

It's about a 1/4' circle and the scale is still attached like a flap.

She shed in one piece but somehow ripped that scale loose.

I dabbed it with Betadine and patted the scale flat.

Will it heal closed or fall off?

She and her sister are both 'soakers'. [no mites, though]

Could her soaking her head have caused this?

Her sister shed yesterday too and is fine.

How often should I dab on the Betadine?
