They should be cleaned and taken care of on a regular basis. Also a close eye should be kept on them so as to prevent all forms of accidents
be as clean as you possibly can! it can lead to the worst side of things if you arent. Make sure to use peroxide and not to use that leg for much, try to stay off of it until you end up at the doctor's. Hopefully they give you antibiotics to fight off bad stuff. Hope for a full recovery!!
