Introducing a new puppy to an older dog requires patience, supervision, and a gradual approach to ensure a smooth transition. Start by allowing the dogs to sniff each other's scents through a closed door before the actual introduction. When you introduce them face to face, choose a neutral territory to avoid territorial behavior. Keep the initial meetings short and positive, and always supervise their interactions. Allow the older dog to set boundaries and take breaks if needed. Provide separate spaces for each dog to retreat to when they need a break. Over time, as they get more comfortable with each other, you can increase their supervised interactions. Reward good behavior with treats and praise to reinforce positive associations.
