My doberman continues to gn..

We learned that dobermans can be sensitive to dog food with corn meal, so we have changed to lamb and rice formula. Tough this has helped tremendously, he still has areas that he will scratch and bite until they bleed. I have hot spot/tea tree oil spray to help sooth a bit. He doesn't have extremely dry skin, so he is not flakey, as a lot of this breed seems to be. Are there other tricks/remedies I could try?

Thanks!!

It may be a nervous habit. When does he do it more? Is it when you are gone? This could be a sign of "Seperation Anxiety" this is common in dogs when they are taken out of a normal routine or are seperated from their owners for times longer then normal. Did you switch hours at work? Went on a vacation? You may want to get him into the vet to have him checked out. If its seperation anxiety there are pills that you can give him when you are gone to help him relax.

Is there any corn at all still in the food? Also chicken can be bothersome, check for chicken fats etc.

If he is just dry, add some Omega 3 oil to his diet. Ours eat the capsules and are fine with it. Some dogs like the oil dribbled over their food. Helps alot with a dry winter drying out their skin.

What colour is he?
