One reason people pick a specific dog breed is for home protection. Dogs bred as livestock guardians, like the German Shepherd or Anatolian Shepherd, have a natural instinct to protect their flock and family. Guardian dogs and breeds used as guard dogs tend to have a natural distrust of strangers. But being able to sense if someone is untrustworthy is something completely different. Do dogs have a sort of sixth sense about people?
My first dog was an American Eskimo named Jack. I took him with me pretty much everywhere I went and he was exposed to a lot of different people. Most of the time, Jack enjoyed being around other humans, but there were times he refused to allow someone to pet him, even though I saw nothing out of the ordinary from the people he pulled away from. However, his reaction to someone was something I noted because it was unusual behavior for him.
We know dogs can sense danger when it comes to certain health conditions. Trained medical dogs can smell changes in blood sugar levels. Dogs are trained to detect high blood pressure, a potential heart attack or an impending seizure, and they can smell different types of cancer. Even untrained dogs can pick up changes in our health. That has nothing to do with a sixth sense, but it does show how sensitive a dogs sense of smell is. Scientific studies have shown that even humans can smell pheromones put out by other people which can give us signals about someones mood. If we can pick up someones pheromones, you know a dog has already processed that information.
Dogs are experts at reading the body language of other dogs and us. Canines living with cats learn to read their body language, too. They can look at our face and tell if were in a good or bad mood. Dogs are great at picking up subtle signs we dont even know were showing. When a dog is around someone whos nervous, excited or angry, they can smell and observe body language that could cause a dog to be apprehensive towards them. People with something to hide have a tendency to look away during conversations, and this isnt missed by dogs. Of course, we can also pick up on obvious signs of nervousness.
Its also possible that if you have a feeling about someone, your dog is picking up on the signals you’re putting out. Dogs know us pretty well, and if you are uncomfortable around someone, your dog is likely to react the same way. Some breeds, however, are naturally wary of strangers and may have a hard time getting close to someone they dont know.
Researchers are learning to be careful when studying our canine friends to make sure dogs arent reacting to cues they put out. Chaser, the Border Collie dubbed the smartest dog in the world, was taught to recognize over 1,000 different objects, as well as the difference between a noun and a verb, and to understand short phrases. To make sure she was actually learning, the person testing her took great care to work in a controlled setting so Chaser wasnt reacting to their subtle cues. Dogs are so good at picking up the smallest signals we dont even realize were sending.
Most of the time, if you have a bad feeling about someone you dont need your dog to reinforce that belief. Over the years, Ive learned more about dogs, why they behave the way they do, how extraordinary their sense of smell is, and their expert ability to read our body language. There is no proof scientifically that a dog can pick up disingenuous intent from someone or that they even have a sixth sense, but Jack did teach me to think twice about someone he had doubts about. He was usually right. If your normally friendly dog has reservations about someone, it may be wise to pay attention to what he’s trying to tell you.
