I suggest try supplementing with: 1. Nordic Pet Omega 3 soft gels 2. Coconut oil 1/4 tsp. per lb. (you may want to split it into 2 servings) 3. HomeoPet Skin & Itch drops
Also apply the coconut oil directly to the skin (you will need to warm it up first by rubbing some in your hand or putting the container in hot water or in the sunlight) then take her for a walk . Try to redirect her by calling her or using a toy when she scratches. You can also use a spray like Natural Touch Chew Not for Dogs.
