I have a 6 month month old puppy that is afraid of people and other dogs. Have taken her to just walk around in pet stores. If someone wants to approach her she squats and pees. If another dog wants to approach her she poops? I live with my son, daughter in law, 2 granddaughters (7 and 13). They have 2 pit bulls and she is fi with them. How do i socialize her outside the family?
