Many dogs notice when someone they’ve never met before comes near them. Some dogs can be very friendly and happy to greet a newcomer, some will be mildly cautious, but some might start to growl, too.
If your dog growls when they see a certain new person, this could be a sign of defensiveness, nervousness, or even aggression. But why is this happening? There are a few possible reasons.
The first reason has to do with scent. Humans have very difficult smells to dogs, and due to the fact that dogs have a sense of smell that can be up to 100,000 times more powerful than a human’s, there’s a lot of information that dogs can discern from just one sniff. There could be something on someone’s scent that is alerting a dog of some unseen danger.
A dog might also consider someone’s appearance to be a little intimidating, often because it reminds them of some kind of threat. The way a person moves, their features, their size, or other factors can cause a dog to react with fear. Even people they’re familiar with can be frightening to a dog just when they put on a hat!
It is possible to teach a dog to be more trusting of other people. Be patient, train them to obey commands, and give them those commands when they show signs of defensiveness, then reward them!
