Hi

. Is she just dry - or is she itching? If so, where? What are you feeding?
1. don't bathe too often - once a week at most; ideally once every 2 weeks.
2. might want to add an
Omega Supplement to support skin; this one can be found at lotsa places, incl. Whole Foods. It doesn't contain flax, which makes some dogs itchy.
3. Try a colloidal oatmeal spray to condition and soothe the skin
4. poss. change foods
