My 6 month old is terrified of people

I am new to having Basset Hounds. My baby girl is 6 months old and lives in the country with me.nshe is used to my family but any time she sees a person she tries with all her strength to pull away. I don’t want to keep pulling her back if that’s making it worse. I’d like to take her to the park and be able to go places without her being so scared. If someone visits she hides and won’t come out Please give me advice!♡♡♡♡
