Our old chocolate lab has cataracts. His name is Wally (we didn't name him lol) and he was the only one in his litter. We've had him for a very long time, well over 10 years.
My dad said that he let Wally into the garage to walk around, since we can't really let him run around anymore cause he'll leave (that and he
doesn't run anymore). When Wally kept bumping into stuff my dad looked at his eyes and they were all grey.

I asked my dad what he was gonna do, and he said, "well, i'm not gonna put him in clove oil." That made me laugh. From what it sounds like there's nothing we can do about it, and dad doesn't wanna put him down, so it looks like we'll just let what will be be.
