As the owner of a giant breed, I fully support licensing, I fully support a all dogs on leads in public open spaces. I fully support mandatory training and certification for dogs.
I know what everyone is inferring, that the dog is going to be a XL bully breed, and I agree more needs to be done about this breed. They have proven to be extremely volatile and involved in many deaths.
I'm just not keen on the idea of every giant or pastrol breed being illegal. Some of the breeds in this group are actually known for their gentle nature, family orientated demeanor, mastiffs for example are a known breed to be exceptionally good with children. They do have a "guarding" instinct but you won't find many mastiffs or even bullmastiffs rampaging for a fight, they are happy and content with their humans and their property, just don't burgle their house.
I live in an area where the XL Bully is a statement dog, and it's a nightmare to walk your own well behaved gentle dog because you are always worried one will jump out.
