I use Colloidal silver 10 PPM in a spray bottle and spray the end of a Qtip and use it to clean the mucous (pookies) out of my standard poodle'e eyes in the corners twice a day. Also good for soaking crusty accumulations around the eyes. Never had any tear staining from day one of owning her from eight week on. She is now 8 years old. Never an eye inflection. Also spray in the mouth to freshen breath.
