FluentPet developer Leo Trottier started CleverPet while a PhD candidate in Cognitive Science at University of California San Diego. We are sharing what we’re learning with the Comparative Cognition Laboratory at University of California San Diego to better understand how it is that dogs and other animals use, and are able to use, sound buttons to express themselves. For more on this, please check out the FluentPet Community for information on how to join (and don't worry, you don't need to have FluentPet buttons to be a part of this!).
