There are no vaccinations that directly prevent aggressive behavior in dogs. Aggression is typically influenced by factors such as genetics, training, socialization, and overall health rather than being directly linked to a preventable infectious disease. However, ensuring that a dog is up to date on all recommended vaccinations helps maintain overall health, which can indirectly affect behavior. A sick or uncomfortable dog may display increased irritability or aggression. Thus, regular veterinary care and vaccinations are crucial for maintaining a dog's health and, by extension, can influence behavior stability.
