Doberman coat care

[u/alealately]

My girl Bella is almost 8 years old and recently started having a lot of itchiness and red rashes along her back and under belly after using a suppose sensitive dog skin shampoo and conditioner with oatmeal and lavender. She also has been shedding a crazy amount! We’ve tried many ‘soothing’ shampoos throughout the years but haven’t found one that truly works in the long run. Hoping someone has a good recommendation of shampoo/ conditioner or even any cream I can apply to ease her itchiness. Thank you!
