Researchers use a thermal camera to measure these temperature fluctuations in pets’ eyes, ears and paw pads.
“Scientists have known for years how to evaluate negative states such as stress and anxiety in animals,” said Ragen T.S. McGowan, Nestlé Purina Petcare behaviour scientist. “Less is known about how to measure positive states such as happiness or excitement.”
“Thermal imaging has been widely used in animal welfare studies, to assess inflammation in racehorses, for example, or to see how certain conditions affect livestock’s stress levels,” she continued.
“This is one of the first times it being used to measure positive responses in pets.”
