Chihuahua
Although Chihuahuas are small in size, they can still pose a potential danger due to their territorial and protective nature. These tiny dogs often develop a strong bond with their owners and can become overly possessive, leading to aggressive behavior. Chihuahuas have been known to bite and attack both humans and other animals, especially if they feel threatened or anxious.
While their bites may not cause significant physical harm, it is important to acknowledge their potential for aggression and ensure appropriate training and socialization to prevent any negative incidents.
