i dont know about the hair loss issue but i think if you notice her skin is dry maybe you should try not bathing her as much once a week is definately enough i bathe my girl like every 8 days usually and use a dog shampoo and conditioner lambert and kay oatmeal and baking soda works great it keeps them smelling fresh and is good for their coat using reg shampoo isnt so good b/c of the ph balance hope this helps! Just a suggestion ! good luck!
