Stella the dog learned to 'talk' and she will change the way you think about pets l GMA

 

Speech-language pathologist Christina Hunger, who helps toddlers behind in their language development by teaching them to use Augmentative and Alternative Communication (AAC) devices to express themselves non-verbally, decided to teach her puppy, a Catahoula and Australian Cattle Dog mix, to use the device. And the results have been astonishing. Correspondent Nancy Giles reports the fascinating story of Stella, a dog with a lot to say, and is the subject of Hunger’s new book, “How Stella Learned to Talk.” "CBS Sunday Morning" features stories on the arts, music, nature, entertainment, sports, history, science and Americana, and highlights unique human accomplishments and achievements.
