The breed is now illegal to own without an exemption certificate in England and Wales, meaning owners could be taken to court and have their pets seized if they are unregistered.
Rebecca Harris owns Bassaleg Dog Walking Field in Newport, Wales, and is allowing XL Bullys to walk freely on her land, which is surrounded by secure fencing and several gates, with their owners.
Under rules brought in by the Government, all members of breed have to be neutered in order to qualify for an exemption certificate for the ban which came into effect today.
A candlelit vigil will be held outside the gates leading to No 10 where distraught owners will hold onto cute pictures of the hounds ahead of the ban which comes into force at midnight.
