Hunger For Words™ talking pet starter set Every dog can learn to speak just like Stella, the world's first talking dog! Inspired by speech therapist and creator of the talking dog movement Christina Hunger, the Hunger4Words Talking Pet Starter Set comes with everything you need to start your dog's communication journey. As you follow along with the step-by-step teaching guide (written by Christina herself), you'll learn how to introduce your dog to the set's 4 recordable buttons. Use your own voice to record simple words like “outside,” “play,” or “bed,” then use these word buttons for dogs to learn what your dog has to say with the help of Christina's insights and tips. Made from durable plastic and powered by AAA batteries (sold separately), these dog communication buttons are ready for years of communication!
