Dog is tiger cubs' best friend and milk provider

BEIJING, April 13 -- A dog in Qingdao, Shandong province, is breastfeeding four tiger cubs because the tiger mother isn't doing her job.

After it gave birth in a safari park early Monday, the first-time tiger mother apparently didn't know to feed the cubs.

Since the babies had to be fed within 24 hours after birth, workers encouraged a dog, which recently gave birth to some puppies, to feed the cubs.

The dog previously provided milk to some baby wolves.
