Raised by Dogs.

From the website:

Miss Malaya is a feral child, one of only about 100 known in the world. The story goes that, when she was three, her indifferent, alcoholic parents left her outside one night and she crawled into a hovel where they kept dogs. No one came to look for her or even seemed to notice she was gone, so she stayed where there was warmth and food — raw meat and scraps — forgetting what it was to be human, losing what toddler’s language she had and learning to survive as a member of the pack.

A shameful five years later, a neighbour reported a child living with animals. When she was found, at the age of eight in 1991, Oxana could hardly speak and ran around on all fours barking.
