So far like this product
Use on my geriatric chihuahuas.  One has only one eye left, having lost his other eye to corneal endothelial dystrophy (CED).  I was concerned he would lose the other eye also.  The other chihuahua has the start of cataracts.  I use this to stay ahead of their diseases.  Been using it since Feb 2016 in addition to other meds required for the CED and his eye is clear of ulcers.  The other chihuahua has been using it since Jun 2016 and her eyes are clear still.  Wish they made something for loss of hearing...
