7 Popular Dog Breeds that Don’t Like Strangers

Top 7 Wary of Strangers Dog Breeds for Loyal Protection

What is more comforting than coming home to a pup who is ready to jump on you and greet you? Dogs are social animals! They play with their littermates, need attention and care from their mother, and make great companions with their humans.

Dogs exhibit attention-seeking behavior when they feel bored or frustrated. Another possible reason is that they might not be getting enough exercise for adequate mental stimulation. Or sometimes they are genuinely not getting enough attention.

Dogs are known for their loyal and affectionate nature. While most dog breeds crave for the love and attention from their humans, many breeds are naturally protective and wary of strangers. In other words, dogs can also be introverts just like humans.

Here are 7 popular dog breeds that are not so friendly with strangers.
