Here Mals are becoming popular because they are popular enough that people know they are good guard dogs but are one of the few protective breeds that aren't popular enough for apartment building to list them as breeds you can't own
Which really sucks for the dogs.. because in many of these situations. The people would've been much happier with another protective but lower energy breed.. but chose the mal simply because they could and ended up with a dog that is too much for them.
