Good question. So I asked. Here is their response:
"Hi and thanks for your question. Yes, this is a pet friendly show. The only thing we ask is the dog be on a leash. We don't want anyone, including our wonderful furry friends, getting hurt or scared and run off.
I was called away to a funeral in Linglestown, PA not far from the Carlisle fairgrounds. Sorry you call couldn't go have fun at the White Plains Show. But glad I didn't miss the fun.
