Chihuahuas are often stereotyped as being loud and full of attitude, but a TikTok video shows that they can be polite and well-behaved. The video features an army of Chihuahuas owned by a breeder and handler. Even during a potty break in a park, the Chihuahuas remain calm and quiet. While Chihuahuas are known for barking, they can also make good guard dogs due to their loyal and protective nature. Training Chihuahuas to be polite requires consistency, clarity, and positive reinforcement. With proper training, Chihuahuas can become well-mannered and polite pets.
