Introducing your dog to a new partner can be nerve-wracking, but it doesn't have to be. Start by introducing your dog and partner in a neutral location, such as a park or on a walk. Allow your dog to approach your partner on their own terms and provide positive reinforcement, such as treats and praise, for good behavior. Gradually increase the amount of time your partner spends with your dog, and always supervise interactions until you are confident that your dog is comfortable.
