"We came over to show the children that the character in the book is a real dog - I thought they might like to meet him and be able to relate to him
better," Willy's owner said.
"Willy has given me the opportunity to make a difference in the lives of many other people. I'm so thrilled to be able to share him with everyone," she added.
More than a hundred students turned up to meet Willy.
"When I see dogs like him, I wish I could put them on a wheelchair," said eight-year-old Atom Maki.
