Introducing a new puppy or dog to a household with an existing dog displaying aggression requires careful planning, patience, and understanding. Before deciding to bring a new furry friend home, evaluate your capacity to manage both dogs' needs, including space, time, and emotional energy. Recognizing and managing aggression triggers and employing controlled introduction techniques, such as supervised walks and gradual closeness, are key to fostering a safe and harmonious environment. If your dog exhibits consistent aggression, seeking professional guidance early is essential to ensure the well-being of both pets and family members.
