For Essendon resident James Rufatt, the importance of his black labrador Kyros is never forgotten.

"I appreciate it and the life-changing benefits that it brings to my life and my family," he said.

Mr Rufatt was born with detached retinas and developed cataracts when he was 12.

After an unsuccessful operation his sight further deteriorated.

The 39-year-old was given his first guide dog, black labrador Edrick, in 2000.

Edrick died recently from cancer, ending a long-standing friendship.

Mr Rufatt said warming to Edrick's replacement initially took time.

"It was very difficult. He [Edrick] was not only my guide dog but my little buddy, protector and soulmate.

"You've got to get over issues. There was a sense of betraying Edrick because we were so close. But I've gotten over it now. Things are good with Kyros."

Having a guide dog had increased his independence. "It gave me a feeling of breaking down boundaries. Without a dog I felt limited as far as travelling. With a dog those limitations have been removed."

Kyros had also helped him when simply talking to people.

"It's an ice-breaker. People seem to be more relaxed around Kyros."

International Guide Dog Day is tomorrow. The event celebrates the important role that guide dogs play in helping blind and vision-impaired Victorians travel safely.
