That dog, if assessed, would match the 'type' of a Bully XL - as would other dogs, such as some Labradors. The difference is that Labradors are a breed that's recognised by the UK Kennel Club and would be exempted from the Bully XL legislation. The Cane Corso isn't a recognised breed in the UK so, if it matches the type for a Bully XL, it can be seized, assessed, and put down.
All owners of Cane Corsos should apply for exemptions, get insurance, chipped, neutered and muzzle in public to avoid that happening.
They won't, of course, because they're convinced that their dogs aren't covered by the ban. They are due to measurements and appearance.
Personally, i think they and a lot of other breeds should have been banned at the same time as the Bully XL to avoid their numbers exploding as people attempt to work around the ban on killer dogs.
