“She has the attitude of a big dog; she would let me know if anyone was around and she would try to guard me if she could.” said Lana.
Gibson and his owner Sandy Hall from Sacramento, California regularly visit children’s hospitals, also making him the world’s tallest therapy dog.
“He just puts a smile on people’s faces.” said Sandy. “In one split second, people forget their cares and worries.”
