if bleeding and/or rawness is occurring do not continue to remove the shed. soak the gecko in betadine instead of water and put some neosporin or triple antibiotic ointment on the toes that bled and on the toes that still have shed on them. (if you don't have betadine immediately available go ahead and use the neosporin now and try to get some betadine asap.) make sure that the paper towels in the humid hide are moist at all times.

what are the temperatures in the gecko's enclosure and how are you heating it?
