What dose it mean if ur dogs eyes where brown and now they are like blue with like fogeynest to them

It might just mean you're cuckoo and just seeing things. Maybe you just need to get your eyes checked. Either that or your dog has an eye disease. You should take it to the vet. They will tell you if there is something wrong with your dog or if it has an eye disease.

Sounds blind. Is he old? You should get a seeing eye dog for your dog. Just kidding!
