Are Service Dogs allowed on Destin beaches
According to the following http://www.emeraldcoastfl.com/faqs.html ..."Okaloosa County Ordinance 77-19 Section 6 Dogs in public parks, beaches, school grounds, restaurants, food stores illegal (Except seeing eye dogs)"You could probably call the Visitor's Bureau directly and find out if that applies to all service dogs, which it should, since they aren't just someone's pet.
Service dogs are not allowed on Destin beaches. However, there are some hotels within the beach that these dogs are allowed. See more details at http://suite101.com/article/dog-friendly-parks-pet-friendly-beach-hotels-in-destin-florida-a254054.
