No one can be more alert than a dog at a scene when a new person arrives. He becomes instantly aware of every move and attention he has, and then you should expect one of two things: He is going to play and cuddle with the person, or he would growl to the point they become scared.
Usually, the growling indicates defensiveness, aggression, or anxiety. But have you ever noticed that your dog would growl only at some people, while they let others be at peace? Especially that they have never seen these people before…
It always makes you think if your pooch might know something you don’t, or they just can smell their bad intentions toward you. In any case, there is definitely a reason why your dog chooses to growl at that one specific person, and we are here to explain.
