Can you explain the difference between dry and wet gangrene?

Infected or not: Dry gangrene is like a piece of leather and does not need immediate treatment. When dry gangrene progresses to being infected then we call it wet and this needs immediate treatment. Gangrene is considered wet when there is drainage, cellulitis or a foul odor.

Yes: Dry suggests dead, non viable tissue while wet describes an active infection where backers are living off the dead tissue.
