There’s no doubt that dogs become very attached to their human companions and are very loyal, loving creatures. Some people may even trust their dog’s judgement when it comes to meeting someone new. But, do dogs really have a sense of stranger danger?
While there is no scientific evidence to prove that dogs have a sixth sense about a person’s intentions, dogs are good readers of subtle facial expressions and body language. If your dog usually likes everyone and is all of a sudden suspicious of someone you encounter, it’s not crazy to keep your guard up.
However, it’s important to note that some breeds, like German Shepherds and Rottweilers, are natural guardians and may have a general suspicion of strangers. Also, dogs that aren’t well socialized or have had a traumatic past aren’t terribly likely to make friends with a stranger, no matter what that person’s personality or intentions may be.
Long story short, always veer on the side of caution. If something seems off to you, whether it be due to your dog’s reaction or your gut instinct, immediately remove yourself from the situation.
