Dogs know their humans’ scent and will prioritize it over everything else

If you’ve seen dogs on TV use their nose to save humans in danger, you should know that it’s not fiction. The sense of smell is one of the dog’s most important senses, and they use it to understand the world around them. According to a study in 2014, scientists wanted to examine the canine ability to differentiate between the scents of familiar dogs & people versus unfamiliar ones. What they found was that dogs prioritize their human’s smells over everything else. It lights up a reward centre in their brain, and fills them with joy.
