Owners everywhere have an instinctive urge to communicate with their beloved pets, but the holy grail is to truly understand what they are saying to us and discovering what they think and how they feel. Now, with the help of brand-new science, ES we discover how every animal has their own unique way of expressing themselves, and the incredible new technology that's helping us to understand them. From the dog communicating with his owner using a system of buttons, to the parrots fooling Alexa into adding their favourite treats to the weekly shop, the rats constantly chatting away just above our hearing range, the guinea pigs born communicating, the rabbit helping an autistic child and the sniffer dog communicating with his owner to help to save the last Northern white Rhino on earth. We explore the extraordinary science behind interspecies communication.
