Dogs can detect heat with 'infrared sensor' in their nose, research finds

Dogs have a type of infrared sensor in the tip of their nose which enables them to detect minute changes in temperature such as when other animals are nearby, according to new research. Scientists at Sweden's Lund University and Hungary's Eotvos Lorand University say the discovery can help better understand how predators detect their prey when other senses such as sight, hearing or smell are hindered.
