Dog-friendly beaches are not usually hard to find, but it can take some investigating. Many beaches that allow dogs have rules from requiring them to stay on a leash and keep out of specific areas to rules for you about picking up after your dog. If you have a particular beach in mind, call the beach management office or look online to familiarize yourself with the rules. If you'd like to let your dog run free, you might need to search for a beach that allows dogs to run off-leash.
