Hey there...I'm late to the party here, but our girl has a cloudy eye that is the result of of her having had a corneal ulcer on that eye. Two, actually. She had one that eventually healed on its own, then about a year later, it recurred. We were told she would need surgery, and that even then the problem might recur, and she might not have good vision in that eye. My thinking was...who cares if she can't see out of one eye, her other one is still perfectly good and that isn't her primary sense anyway. So, when the pain started to diminish right before the surgery, we chose not to have it and let the eye heal up on its own. Since then, she's had the cloudiness and her vision is definitely compromised, but it doesn't slow her down in the slightest. I think she just can't see things that are far away, basically. We've been super fortunate in that she hasn't had a recurrence since then (over two years ago).
The cloudiness is basically scar tissue, I think, so it makes sense it'd be hard for her to see through it. I guess...long story short...if your rescue pup isn't bothered by it, then you shouldn't be, either. If it was an active ulcer, you would definitely know...they are extremely
painful and she wouldn't be able to let it alone.
Hope this is helpful. Bless your heart for taking in these strays, btw...that takes a special breed of person.
I don't think I have the heart for it...I'd have a house full of pups I'd never be able to let go of...they'd call me the 'crazy dog lady.'
