I have a jack russell that has allergic skin rash that she will rub, lick, and scratch until she makes scabs. I had tried everything from home remedies to vet visits and nothing worked. Finally I bought some T-gel soap for humans, it has tar in it, lather, leave in 5 min., rinse, repeat 1x week......amazing, no more rash! Just be carefull not to get it in dogs eyes.
