Accra lick dermatitis on my Brittany ,Help?

[6.5s4ever]

Hi everyone ! I have a 8 yr old Brittany Spaniel and he has a spot on the top of his left front leg where he has licked it so much the fur is gone it looks like a hot spot but is not . My vet called it accra lick Dermatitis its a skin condition caused by him being bored and licking the same spot all the time. Has anyone experienced this on their dog and could give me some advice on what to do. I have tried the Kong Ball to keep him occupied while I am working be he doesnt seem interested in toys. I tried a gauze bandage with adhesive tape over the area but he keeps chewing it off. advice or ideas appreciated Thanks Roy
