8. Wolf Hybrid

Just as the name suggests, the Wolf Hybrid is precisely that, a mix of a dog and a wolf. Although dogs themselves originated from wolves, canines were mix bred and domesticated over the years, therefore differentiating them from the wolf. Due to this, having a wolf hybrid also causes alarm as to whether you have more wolf than dog, therefore their personalities are highly unpredictable.

9. Boxer

Although boxers are known to be family dogs, they have also apparently been involved in 48 unfavorable incidents where they have shown aggression. They do get along with other dogs, as long as they have been properly mingled with others from a young age. They do require an immense amount of attention so they are perfect for families looking to do lots of outdoor activities on a daily basis. They are even known to suffer from separation anxiety if left alone for too long.
