My granddaughter, ll years old, has Downs Syndrome. About ten days ago a pet dog lightly bit her hand. Now the skin there has turned purplish and is rough skin, not an open wound, it is closed on the two puncture sights. Now another similar spot has appeared on the same hand (all on top of the hand). Also, both hands had peeled on the palms and fingers. Skin has peeled off and new skin is pretty red. And her heels are peeling, too, but don t look as scary. Please tell me what this is? Thank you so much. Sandra Rollins
