2. German Shepherd
While they are popular pets, there are many cases where the dogs have turned on their owners or someone in the household.
They are aggressive and self-assured dogs that often exhibit protective behaviors for their human family. Even so, some poorly socialized German Shepherds have been known to attack and even kill.
Just this year a thirty-five-year-old woman was attacked and killed by the family German Shepherd. Statistics show that these dogs are among the top five most likely to bite.
While these dogs are extraordinarily smart and alert, they were originally bred for work. As working dogs, they have been used and trained by the military and police for various occupations in their line of duty. While they may be suited to their jobs in the line of duty, they may not always be suitable for the role of family pet.
Though they can be fun-loving and loyal, people should not ignore the fact that they have the capability to do harm as some have discovered. In fact, their energetic and fun loving nature can easily make the leap to excitable and aggressive depending on the situation they are faced with.
