Ananova:

The parents of a dieting Italian boy have worked out why he was still putting on weight - he was stealing the dog's dinner.

They solved the mystery when the dog bit the boy on the bottom and they realised he had been eating the pet's food.

The 10-year-old from Frosinone was told to go on a diet after he tipped the scales at seven stone and 12 pounds.

The boy's father told local media they had noticed the dog was looking thin, but had not made the connection.

The boy's parents have reportedly asked their doctor to devise a lighter diet for their son.
