I bath mine every two weeks because of all the reasons already stated. I use Royal Treatment products... which I love. Just about every 3-4days I use the spray on conditioner and brush out their coat... along with clean their eyes and ears really good. The conditioner makes them smell like a giant oatmeal cookie and I gives them a little shine. It last for days. The brushing helps them not look all messy. I also shave around the private areas so that nothing "sticks" to the fur (ewwwww). That keeps my dogs smelling quite nice
