Ponca City, We love you writes "The Telegraph reports that researchers using tests originally designed to demonstrate the development of language, pre-language and basic arithmetic in human children have found that dogs are capable of understanding up to 250 words and gestures, can count up to five and can perform simple mathematical calculations putting them on par with the average two-year-old child. While most dogs understand simple commands such as sit, fetch and stay, a border collie tested by Professor Coren showed a knowledge of 200 spoken words. 'Obviously we are not going to be able to sit down and have a conversation with a dog, but like a two-year-old, they show that they can understand words and gestures,' says Professor Stanley Coren, a leading expert on canine intelligence at the University of British Columbia in Vancouver. Dogs can tell that one plus one should equal two and not one or three,' says Coren, adding that dogs 'can also deliberately deceive, which is something that young children only start developing later in their life.' Coren believes centuries of selective breeding and living alongside humans has helped to hone the intelligence of dogs. 'They may not be Einsteins, but are sure closer to humans than we thought.'"
