One way to help a dog feel more confident is to use repeated exposure to the scary thing so that it becomes less novel and more routine, this is called desensitization. If you want to get your dog comfortable with, say, going to a popular park, first bring them to a quiet corner of the park and allow them to see and hear other people and dogs from a safe distance. Observe their body language closely to get clues about how they're feeling. Over many short sessions, you can move incrementally closer to the busy walkways and more crowded areas, always watching the dog for signs of discomfort. If you’re unsure how to make an exposure less overwhelming to start with, think about how you can manage factors such as noise level, amount of the stimulus, and invasiveness or distance from the scary thing. You can enhance the desensitization sessions by adding really yummy treats, called counter-conditioning, this technique involves the animal experiencing a very tolerable exposure to a stimulus, followed by a delicious treat. To build your dog’s confidence in a more general way, provide them with enrichment activities and relationship-based training. Simply feeding your dog via food puzzles and getting them involved in nose work can make them more confident. Training your dog using positive reinforcement teaches them that making decisions and engaging with you and the environment earns them good things like treats and praise. Proceed at whatever pace your dog appears to feel safe. Implementing desensitization and counter-conditioning effectively is all about timing and knowing when to move forward and when to go back to the previous step.
