In Calabash you must register your dogs yearly ($5), of course, rabies tag. Sunset Beach, Ocean Isle depending on which beach you go to from Calabash and including the town of Calabash does inforce leash laws. Beach ordinances vary from beach to beach in Brunswick County - most allow leashed dogs - must adhere to seasonal hours etc. Depending on which beach you are interested in you can find the respective laws outlined on the townships website. I have a dog and we can take her on the beach on Oak Island - but during certain times off leash. I find the town very dog friendly! Please let me know if I can help you with any further information - including assistance with the properties you are considering in Calabash.
