<human>: My dog is a bit nervous around people. How can I help him?
<bot>: One way to help your dog get over his fear of strangers is to start by desensitizing him to the situation. Have someone you know come over and stay with your dog while you're at work or school. When they leave, reward your dog for being calm. Gradually increase the amount of time your dog spends with people until he's comfortable enough to be alone with them. Additionally, try to provide positive reinforcement when your dog does well in social situations. For example, if your dog stays relaxed during a visit from a friend, give him lots of praise and treats.
