00:04In the daytime he's fine, but the second it gets dark, he just can't see a thing.
00:11He freezes.
00:25So Rio takes over, the moment the lights go out.
00:29Out to the garden, down the step he can't see, Rio walks him the whole way.
00:54And brings him safely back in, every time.
01:10Water in the dark, back to his bed, he'd never find them on his own now.
01:18Rio knows the whole house in the dark, so Duke doesn't have to.
01:29Here's the strange part.
01:31Look at him now.
01:32In the daylight, he's absolutely fine.
01:35But once it's dark, his world just disappears.
01:39So every night, the young one takes the night shift, guides him to water, out to the garden,
01:45back to bed, his eyes from dusk till dawn.
01:49Nobody taught him when to start.
01:52He just watches the light fade, and steps in.
01:58Every single night.
