To help a shy or fearful dog gain confidence, expose them to what frightens them at a low intensity and pair this exposure with something positive, like a tasty treat. Allow your dog time to get used to people, and instruct others to ignore your dog, letting them decide whether they want to approach someone. Dogs that adjust on their own are more likely to approach people safely. Approach dogs at their level, crouch down or sit on the floor, and don't stand over a dog. Throw out treats, decreasing the distance for a safe interaction, and don't interact with them until they're ready to take a treat from your hand. Build up trust with your dog before bringing them to public settings like the dog park, a friend's house, or a dog-friendly restaurant or brewery. Putting your dog in a stressful situation will set their progress back, so go slow and give them time to gain confidence and trust. Be your dog's best advocate, and keep an eye on their body language to get to know their signs of stress or fear. If strangers approach your dog and you don't feel they're ready to meet, it's always okay to say no and step between your dog and the other person.
