Juan Dolio, in the Dominican Republic, is considered relatively safe for solo female travelers. The locals are generally friendly and helpful. However, like anywhere else, it's crucial to exercise common sense such as avoiding isolated areas, especially at night, keeping an eye on your belongings, and not sharing too much information about your accommodation or itinerary with strangers. Take note that petty thefts or pickpocketing can still occur, mostly in crowded tourist areas. Always keep in contact with your loved ones back home and provide them with your travel plans for safety.
