A sick little girl is being kept alive thanks to her best friend – a dog who carries her oxygen tank on her back.
Alida Knobloch’s faithful canine companion Mr Gibbs has been specially trained to shepherd the three-year-old, who breathes though a tube most of the time.
He follows her closely as she plays in her family's ten-acre land in Louisville, Georgia, uses the slide or even rides her bike.
Alida, who was diagnosed with neuroendocrine hyperplasia of infancy (NEHI) when she was just eight months old, is able to breathe without the tube.
