Man’s best friend? Well that’s what you would think all dogs are, but this is not true for all dogs! Researchers and critics do not necessarily agree on what factors make these dogs dangerous. In other words there is no unanimous opinion regarding the criterion of declaring the animal, dangerous. Dog lovers too disagree on this aspect that these dogs cannot randomly be assigned the tag of ‘dangerous’ and be banned in some countries. At the same time, it can also not be ignored that some breeds of dogs are potential threats to their human counterparts. They can be extremely aggressive and cause serious harm to humans. Though dogs are essentially bred to protect their masters and bring unconditional love to the families that own them, some of these breeds turn out to be truly dangerous to others. The reasons do not rest with the breed or the dogs as much as do their nature of ownership and treatment by their masters. It has been found that some dogs are trained to be aggressive and attack strangers in their sight no matter who these people may be. They are treated harshly and grow up to be ferocious creatures with any sense of discerning. It may be appropriate to say that most of these attacks by dogs on innocent people are a result of deliberate training to harm and inhuman ownership attitudes. Despite logical reasons for any kind of attack however, some breeds are inherently more lethal than other dog breeds. Let’s know a little more about 10 of the most dangerous dog breeds from around the globe.
