If an eye goes cloudy it's the fusithalmic gel you need. I've used it on my dogs for years and it works well. It aint cheap but what value do you put on your dogs sight.
Yep, all the time mate. You'll have to check their eyes in case they have a thorn in there somewhere. If the dogs eye goes cloudy you'll need to see the vet. I keep a supply of fucithalmic gel in the house just in case.
