Do you want to know whether your dog loves you or not? Watch his left eyebrow to get the answer!

Researchers used high-speed video cameras to capture the micro facial expressions of 12 dogs from different breeds when they were faced with various objects for 800 milliseconds. Each dog was lead into a room that was divided by a curtained partition. When the curtain was briefly parted, the animal may see one of the following objects: his owner (the owner was required to show no emotions), an unfamiliar person, one of his loved objects like a squeaky ball or an object that it fears such as a nail clipper. The researchers used blue tapes to pinpoint the animals’ facial tics. The dogs showed different facial expressions depending on what they saw and the scientists recorded the whole behavioral process.

When the animals saw a person, their left eyebrows were lifted while if the person was the owner, they would raise their left eyebrow even higher. In the video, when its owner appears, the poodle’s eye slightly widen as it raise its eyebrows and drop its ears. When the dogs found the object was a stranger, they moved their left ears back slightly, which is a sign of caution. The beloved toys triggered no response, while the horrible nail clipper caused the dogs to twitch their right ears—probably a sign of a learned response which is governed by the left side of its brain.

Some of the results are confusing, said the researchers. The previous study has showed that the dogs’ positive emotions are usually expressed on their left faces. Why did the pooches lift their left eyebrows when saw their owners? One possible guess is that this is because of mixed emotions—something the dogs were not know to experience. Upon seeing their owners, the animals felt happy while they were blocked by the curtain that partitioned all important touch, which made them sad.

Editor’s note: Just like humans, dogs can have mixed emotions!
