If online events calendars are any indicator, South Carolina is barking nuts over Yappy Hours: few-hour, dog-friendly events with live music, food, drinks and activities that even stretch into the colder months.
We did list a haunted walking tour above, but there are plenty more dog-friendly walking tours available in cities all across the state (especially the larger ones). All you need to do is bundle up and buy a ticket and you'll partially keep warm from walking, get some exercise, and spend some good time with your dog outside.
Most of our activities mean staying outdoors, but if it's too cold or the weather just isn't right, find a nearby dog bakery to check out. It'll be a great spot to keep warm and get your pup a special treat they don't get to have every day.
