With some assistance and teaching, cats and dogs are capable of learning to speak in sentences. In 2018, a speech pathologist named Christina Hunger, who used AAC devices to help special needs children learn to talk, tried applying a similar approach to her dog, Stella. It worked surprisingly well. Stella could speak in four-word sentences with a vocabulary of around 15 words by her first birthday, and was up to 49 words by her third birthday. Since then, many other people have followed the same process to teach their pets how to talk.
