They are not banned, just restricted. You have to get a special licence from the ministry.
However, you would have to import one, and as most imported pups come from Egypt, it hardly seems worth the bother. Pups from Egypt often arrive in Qatar in a bad state, vaccination details have been forged and you have no evidence that they are pure breed.
My advice, and I do know what I am talking about, is don't. Why do you want such an aggressive looking type of dog anyway? Do you have a huge palace to guard? You want a potential killing machine, are you qualified to train it in order to protect other dogs, cats and the general public?
It seems to me that you are looking for a dog that makes you look good.
