A new study published in Neuroscience and Biobehavioural Reviews explains that dogs are entirely capable of knowing when a human is being a bit of a dick to another human.
The study also found that dogs use this information to influence how they interact with you.
So your dog can see when you’re not being very nice to other people, and that impacts how they view you. Sorry.
Dogs are capable of judging humans’ not very nice behavior – and they’ll reject them if it’s clear that they’re terrible people.
So in short: if you’re being horrible, your dog knows about it. They’re judging you on it. And if you want your dog to like you, you’d better shape up.
