Natural Tears is completely safe to use on dogs, and you probably don't want to know how they test it to determine it's safety for human use. I can tell you that allergies cause most eye discharge. The eyes become dry and itchy , the eyes then try to compensate by overproducing tears, if you keep those allergens rinsed out the tear production will level out, just like human eyes. If you pay close attention during spring and fall the goo is usually much worse. When the eye becomes dry during these times of the year more damage can be done by the dust and debris scratching across the eye every time they blink. |
