Paragraph 2
The researchers conducted
on sixteen dogs that had to detect the
of different objects in a room. The
had different temperatures that humans could only differentiate by touching
. The scientists said that the brain activity in the dogs showed that they could discern which objects were
than others. Anna Balint, lead author of the study, said: "Dogs are able to sense the
radiation coming from warm bodies or weak thermal radiation, and they can change their
according to this signal." Another scientist said scientists should now re-evaluate how
hunt. Many may use heat-sensing
to track or sense their
.
