IMO taking her out in public even on leash is a risk! Ive been around males when females have been in heat and quite frankly they will do ANYTHING To get to them! I wouldnt take her to the beach! Yeah they make doggie diapers lol but I always found it cheaper to get boys undies and put em on backwards so their nub can go through the hole lol Then just put a maxi pad in there. Im sure someone else will have more info.
