Dogs displaying which type of aggression may have a problem with strangers?

The correct choice is dominant aggression. Dogs exhibiting this type of aggression often perceive strangers as a threat to their status or control over their territory. This mindset can lead to aggressive behaviors in an attempt to assert themselves or establish dominance in the presence of unfamiliar individuals.

Dogs that show dominant aggression may act aggressively toward those they view as lower in rank or unfamiliar, forcing them to respect their authority. This behavior is less about fear and more about the desire to impose control or assert their rank in the social hierarchy.

Understanding this can help in assessing a dog's behavior and ensuring proper training or modifications to address the underlying issues effectively. For other forms of aggression, such as fear or defensive aggression, the motivation stems from insecurity or a need to protect oneself, rather than a drive to assert dominance. Playful aggression, on the other hand, is characterized by exuberance and is not typically directed toward strangers in a threatening manner.
