TBF I do think there’s a cultural aspect. If you search for ‘XL bully’ half the video results are about how to get your bully XL dog to build muscle mass and look intimidating. It seems people that are attracted to that breed are so because they desire (at least on some level) to have a dangerous looking dog, and actively work to make the dog fit the role.

I’m unsure how you address that behaviour, but it is a problem.
