Chance often scratches his chin. Several days ago I noticed that he has little scabs of blood on his chin. Could this be from the cold weather making his skin dry? Should I worry or just keep a close eye on him? I haven't noticed this before but have only had him since the end of June. Should I put something on it? I have panalog cream. Oh' one more quick question...what are "foxtails?? I saw a post from Nanabear and her dog had "foxtails in his nose". Very interesting. Thanks!!
