Natural Instincts:

Dogs have natural behaviors they’ve received from their wolf ancestors. In the past, these behaviors were useful for staying safe. When they bark at people they don’t know, it’s because they want to protect you. It’s like a signal to say, ‘Hey, there might be something we should be aware of,’ similar to how wolves would howl to tell their group about possible danger

Territorial Instincts:

Dogs are naturally protective of their space. Even though your dog is friendly to people, they still have a sense of ownership over their territory. So, when unfamiliar people like the postman or your new friend visit, your dog might get a bit nervous. They see these visitors as potentially unwanted. For some dogs, especially those bred to be guard dogs like German Shepherds and Mastiffs, this protective barking is quite common. It’s their way of alerting the family and scaring away what they consider as unwanted guests.

They’re Raising The Alarm:

When dogs bark at strangers outside their familiar places, like during a walk or at a park, it’s often alarm barking. This happens when dogs haven’t met many new people since they were puppies, and they’re anxious around unfamiliar faces. Alarm barking doesn’t always mean a dog will be aggressive. They might just be trying to alert their family. When the stranger comes closer, the dog might get nervous and calm down or avoid them.

To stop alarm barking, boost your dog’s confidence with positive reinforcement. Use tasty treats or their favorite toy to show them that strangers aren’t scary.

Fear and Anxiety

Sometimes, when dogs bark at people they don’t know, it’s because they are scared or anxious. They’re basically saying, “I’m afraid, and I want this person to go away.”
