Today's Oprah devoted a full hour to dogs. Oprah mainly had on dogs that can do cool tricks (one Jack Russell Terrier can add, subject, multiply and divide), but it was one dog's maternal extinct that made her extra special. A white tiger had recently given birth to a litter in a Kansas zoo, but rejected her cubs and refused to nurse them. Two of the zookeepers, a married couple, had a golden retriever who had just finished weening her puppies, so they brought the cubs home to see if she could nurse the cubs. Interspecies cuteness ensued. Clip above.
