Christina Hunger, 26, is a speech-language pathologist in San Diego, California who believes that "everyone deserves a voice."
Hunger works with one- and two-year-old children, many of which use adaptive devices to communicate. So she wondered what would happen if she taught her two-month-old puppy, a Catahoula/Blue Heeler named Stella, to do the same.
"If dogs can understand words we say to them, shouldn't they be able to say words to us? Can dogs use AAC to communicate with humans?" she wondered.
