Andrei Tolstyk, seven, was abandoned by his parents in the remote region of Russia, according to a news agency.

He was befriended by the family guard dog, who looked after him. He walked on all fours, bit people and sniffed at his food before eating.

He's now learning to walk on two legs and more human behaviour after social services discovered him.

He's now able to make his own bed, and has learned to eat with a spoon.

Although he can't talk yet, he's communicating with other children in an orphanage by using hand signs.

Police are hunting for his parents, to charge them with not caring for him properly.

Andrei's not the first boy raised by dogs in Russia.
