Dogs have incredible senses, including a strong sense of smell, which allows them to remember people they have met. They also have a sixth sense, or intuition, that helps them determine if someone is a friend or a stranger. Dogs are very perceptive of body language and pheromones, allowing them to sense when a stranger is present.
Signs Your Dog has Sensed a Stranger
Dogs can determine if someone is a stranger to your household. They use their social intelligence and senses to pick up on body odors, fear or anxiety, and someone coming from a different neighborhood. Dogs also observe body language and tension, and will alert you through their own body language. This may include raised hackles, a straight or slowly wagging tail, or growling.
Body Language
Other signs that your dog recognizes someone as a stranger include a stiff body posture, flaring nostrils, and raised back hair and ears.
The History Behind Dogs Sensing Strangers
Dogs’ wolf ancestors were naturally fearful of strangers, and would drive them away from the pack. Dogs continue to sense danger from strangers due to negative body language and unfamiliar smells.
The Science Behind Dogs Sensing Strangers
Scientists and animal behaviorists recognize dogs’ ability to sense and remember different smells. Dogs can associate smells with objects and track them. They also have a strong sense of smell that affects their brain responses, as shown through MRI scans.
Training a Dog to Sense Strangers
Some breeds are more predisposed to guarding and protecting their home. While training for guarding is more intense and may not suit all families, it is possible to train a dog to be a good watchdog. However, it is important to distinguish between a protection dog and a family guard or watchdog. Protection dogs require specific qualities and training, while watchdogs naturally alert their owners to strangers. Professional help is recommended for training a dog as a guard dog.
