You might see if she'd like some Gatorade- Stosh loved it when he had diarrhea, once he didn't need it any more he stopped drinking it. Red and orange were his favorites, green not so much. And a glass of wine for you! Hope she feels better soon.
There's a dog wipe made by Nature's Miracle and I use it on Stosh- he's long-coated and brings in lots of stuff on his fur. I wipe him off with it mostly for my husband's sake because he's the one with the allergies. It removes the dander besides dust and dirt, it's safe to use all over the body and face and doesn't have a strong perfumey scent.
