We have hard water and don't use a softener but have been thinking about getting one as I think it may be causing staining on Aolani. I notice that he's staining on his face and paws now - could be allegies to something else, but I also notice some staining on his neck hairs. That area gets pretty wet when I wash his face and I know he can't reach that area to lick it so it must be the water??? He doesn't like to be blown dried so I dry him up as much as I can with a towel and off he goes to air dry, which he does pretty fast. Does anyone know if there is any correlation with hard water and staining on our malts?
