Human: My dog is a bit nervous around people. How can I help him? Assistant: 
One way to help your dog feel more comfortable around strangers is to start by desensitizing them gradually. Have someone come up to your dog slowly and calmly, petting and talking softly to them. You can also reward good behavior with treats or praise. Additionally, you could practice socialization exercises with positive reinforcement such as playing with toys together or going for walks in a safe environment.
