Which type of aggression is described as being potentially dangerous and is most often seen in male dogs of the same sex?

Dog-on-dog aggression is characterized by aggressive behavior displayed by one dog toward another dog, often occurring during interactions that escalate into a conflict. This type of aggression is particularly concerning because it can lead to serious injuries, not just to the dogs involved, but also to humans who may intervene. Male dogs, especially those of the same sex, are more likely to display this behavior as they may be competing for social status, territory, or mating opportunities.

Understanding dog-on-dog aggression is crucial for dog owners and trainers, as it can manifest in various contexts such as on-leash encounters, dog parks, or even in the home when introducing new dogs. Recognizing the signs of impending aggression, such as raised hackles, growling, or intense staring, allows for better management and prevention of potential fights. Effective interventions may include training, socialization, and careful supervision to reduce the risk of aggressive encounters between dogs.
