Does your dog understand you? All dogs are smart but some are uniquely gifted at learning words. According to a new study, just published in Royal Society Open Science, these gifted dogs can learn up to 12 new toy names in one week. Not only that, but they can also remember the new toy names for at least two months. The dogs presented their exceptional skills as part of the Genius Dog Challenge, a series of live broadcasted experiments, which went viral over social media.
