Four dogs participating in the study found the breath and sweat sample taken from a stressed person in 93.8% of the trials. Sign up for CNN's Wonder Theory science newsletter.
This is because those people are excreting a higher level of pheromones. So even when a dog is familiar with their owner, if that owner is menstruating or just had a baby, they are letting off a different smell and the dog wants to know why.
And it turns out, according to one expert, that your pup knows just how much you care about her. Dr. Brian Hare, who has written books about canine cognition, told People that dogs have emotions and feelings just like we do.
