Why Is My Dog Suddenly Aggressive Towards My Other Dog

It can be alarming and distressing to witness a sudden change in your dog’s behavior, particularly when they become aggressive towards another dog in the household. Dogs are social animals and are usually known for their friendly and sociable nature. However, there are several possible reasons why your dog might suddenly display aggression towards their housemate. Understanding these reasons can help you address the issue and restore harmony among your furry companions.

1. Resource guarding: Dogs may become possessive of their belongings, such as toys, food, or even their favorite spot on the couch. If one dog feels threatened by the other’s presence near these resources, it may resort to aggression to protect them.

2. Fear or anxiety: A sudden onset of fear or anxiety can trigger aggression in dogs. This can occur due to a traumatic experience, a change in the environment, or even a medical condition. It is essential to identify the underlying cause and provide appropriate support to alleviate their anxiety.

3. Lack of socialization: Dogs that have not been properly socialized may have difficulty interacting with other dogs. This lack of exposure to different environments, people, and animals can cause fear or aggression when confronted with unfamiliar situations.

4. Medical issues: Pain or discomfort can cause a dog to become irritable and aggressive. Health conditions such as arthritis, dental problems, or even an undiagnosed injury can manifest as sudden aggression towards other dogs.

5. Hormonal changes: Intact male dogs or females in heat may display aggressive behavior towards other dogs as a result of their natural instincts to protect their territory or seek a mate.

6. Disrupted hierarchy: Changes in the social dynamics within a household, such as the introduction of a new dog or the loss of an alpha figure, can create a power struggle among dogs. This can lead to aggression as they assert their dominance or protect their position.

7. Learned behavior: Dogs are observant creatures and can learn aggressive behaviors from their environment. If they witness aggression or are subjected to it, they may mimic these actions towards other dogs.
