The research has been a major victory for animal lovers and has given credence to those who enjoy talking to their four-legged friends. They are not at a human level of comprehension, and your dog lacks the brain power or structure to ever be able to respond with verbal words as we can, but they are listening to you. Fiddo may not understand every word that you say to him, but he is focused on both the content of the conversation and the underlying emotional tone. He may not understand that you had a rough day at work and that you hate your boss, but he will know you are sad, upset, angry, and in need of love because of the words you said, how you said them, and the emotions you are showing along with those words. He understands you just as well as any human does, it is just in a slightly different way than humans do!
