The web site says: We don't prevent people from bringing their dogs, but we don't recommend it. Every year, we see sad pups holding up frozen paws, limping, shivering and scared of the crowds and loud noises of carnival. It's best to leave them at home in a warm, safe place. They it also say there are nearby dog boarding places.
I cannot answer directly. As a tourist I did see a number of leashed dogs there on Saturday . Have fun if you go.
