I have used this product twice every day for nearly two years on dog with cataracts, small and developing. The cataracts are now severe and nearing the point of blindness. The first 6 months appeared to have slowed the development but now seems to have no affect. The product was touted as being able to reduce and eliminate cataract development. I believe it is no longer of real benefit to the dog.
