Has anyone ever had a dog with lick atrophy? My black lab has it or does it and it is so gross. Basically she licks and lick her legs until she has a sore and then she keeps licking and licking. I've covered the sore, put bitter apple on her around the sore but she still licks and licks. This time she has given her self a really nasty sore. I don't know what to do with her .
