While aggression isn't tied to specific breeds, some breeds might show it more readily if their physical and mental well-being isn't looked after, or if they miss out on proper training and early socialization. This can be because certain breeds were originally developed to guard, herd, or hunt animals. However, it's important to remember that any dog can become aggressive without the right training and socialization.
