We have an old rescue so dont know his age but vet thinks 10+. His eyes had become more and more 'milky' and we noiced he was stopping near to us and waving his head from side to side when out for a walk like he couldn't make out what was ahead. Then it progressed to he wouldnt come down the stairs, and we would have to carry him, then bumping into things on the floor, that normally we would walk around. He has a collapsing trachea so he cant have surgery due to risk. We thought he was going to loose his vision, we would look after him but it was ruining his quality of life. We seen your advert and decided to give it a try, and it is AMAZING within first 3 weeks the milkyness has reduced and his eyes look less opaque. He will come down the stairs, all be it slowly, still bumps into things on the floor, but he is enjoying his walks again and has started to walk ahead rather than at our side. We have also noticed he has started watching things again, as was just sitting staring into nothing. The drops have definitely helped. Will continue to use as directed 4 x a day for remaining months and keep him on maintenance dose. Can't thank you enough. Big hugs from our boy Louis xx
