My dog Murphy is about 11 months old. He has been licking his back right hind leg (not the left) and has been doing so for a few weeks. This didnt seem abnormal because he licks absolutely everything all of the time. But he seems to be obsessive about this leg to lick and now he is starting to lose some hair there and is developing open sores in the area he is licking. I have been directed to purchase some bitter apple stuff that makes things taste bad and prevent them from licking. Any thoughts out there? Anyone have this problem with their dog? Will his hair grow back in these areas where he is licking it away? Is there other ways of stopping him?
