Yes, dogs can exhibit aggression towards other dogs during social interactions. This is a common problem that many dog owners face, especially when their dogs are not properly socialized or trained. Aggressive behavior can range from growling, snarling, and barking to biting and attacking other dogs.

There are several reasons why dogs may exhibit aggression towards other dogs during social interactions:

1. Fear and anxiety: Dogs that are fearful or anxious may become aggressive towards other dogs as a way of protecting themselves or asserting their dominance. They may feel threatened or overwhelmed by the presence of other dogs and respond with aggression.
2. Territorial behavior: Dogs that are territorial may become aggressive towards other dogs that enter their territory or space. This can include their home, yard, or other areas where they spend time.
3. Resource guarding: Dogs that are possessive of their resources, such as food, toys, or beds, may become aggressive towards other dogs that approach them while they are eating or playing with their toys.
4. Lack of socialization: Dogs that are not properly socialized may become fearful or aggressive towards other dogs, especially if they have not been exposed to different types of dogs and social situations during their critical period of development.
5. Hormonal influences: Unneutered male dogs may exhibit aggressive behavior towards other male dogs due to their hormonal influences.

It is important to address aggressive behavior in dogs towards other dogs, as it can lead to serious injuries or even death. Dog owners should seek professional help from a certified dog trainer or behaviorist to address aggressive behavior in their dogs. Treatment may involve socialization, behavior modification, and management strategies to prevent aggressive incidents. In addition, dog owners should always supervise their dogs during social interactions and intervene if they notice signs of aggression, such as raised hackles, stiff body posture, or growling. With proper training and management, many dogs can learn to interact safely and positively with other dogs.
