They can smell fear, but can they smell truth? Your dog may be smarter than you think. It turns out that dogs are pretty good at detecting human behavior. Science says so. A study was conducted that found that dogs really know whether or not they should believe you.
The study involved fooling the dogs in the name of science. Humans have known for a long time that if you point at an object, a dog will run towards it. The researchers used this information in their study. During the experiment, they pointed to a container that was filled with hidden food. Sure enough, the dog ran to the container. They then pointed to a container that was empty.
