dog losing weight and going blind??

what would cause a dog to consistently lose weight even though it is eating constantly, the dog has started to lose vision in both eyes (cloudy appearance to corneas) and has had problems with incontinence. The dog was recently on prednisone but was taken off due to incontinence issue. Please help.

One side effect of long term predisone use is cataracts.  Was your dog on prednisone for a long time?  How old is the dog?

What has the vet said about the weight loss and cloudy appearance of the corneas?

I'm not certain the two conditions are connected.  When unexplained weight loss occurs in spite of a healthy appetite, my first thought is cancer.  The prednisone may have covered up some of the symptoms.  If you haven't yet brought the weight loss issue up with your vet, it's time to do so.

Another possible cause of weight loss when the appetite is still very good is hyperthyroidism. You would need to ask the vet to run some tests for this. But I don't think there would be any connection with incontinence or cataracts.
