A dogs bond knows no bounds, and its not just reserved for humans.

Nearly four years ago, the Siberian husky was diagnosed with glaucomaa condition that caused him to go blind.

Now, Walker is acting as Sterlings unofficial guide dog.

Lillian and Martin McKee are the pups loving owners.

They are also about a year apart in age.

The dogs have long relied on each other to face fears and new challenges.

Sterling took it like a champ, Lillian recalls.

We actually went hiking right after the diagnosis.

As Sterling’s vision started to fade, we fought the inevitable blindness that would come with canine glaucoma.

Despite his loss of sight, Sterling still does many of the things he loves.

He still runs with Martin and Walker regularly, Lillian explains.

We still hike with friends and we still volunteer with Washington Alaskan Malamute Rescue.

We didn’t notice much of a change except that his bond with all of us has grown stronger.

The two pups are so bonded that they miss each other when one is away.

Lillian bathes them together, they nap near one another, and they enjoy outdoor adventures together.

They are also respectful of one another, particularly Walker.

This is not an issue with the boys, Lillian says.

Siberian husky Sterling and Alaskan Malamute Walker are the best of dog friends.

Luckily, he had Walker and his human parents Lillian and Martin by his side.

They bought him special dog goggles so you can help protect his vision.
