We chat about the Genius Dog Challenge, where scientists are finding dogs who know a lot of words, and Stella the dog who learned to use buttons to communicate. We also talk about the words and behaviours our own dogs and cats know--and the behaviours we think are important for every pet to know.Kristi tells us about her courses for people who need help with their dog jumping up or housetraining.And finally we chat about the books we're reading.
