Ever have that one friend that you dog HATES? Well there might actually be something to it!
According to a study that was published in the journal, Neuroscience and Biobehavioral Reviews, a dog can sense when a person is being mean to another person. So maybe your friend is just kinda a Jerk!
In the study they set up a situation where one person needs help opening a jar... and they found that dogs were more likely to ignore the person who would not offer to help that person open the jar.
