I would not go for an am staff in your situation.

i would suggest a boerboel or cane corso then.

GSD shed alot, aswell do the alaskan malamute, CAO.

 the belgian malinois is not calm enough and would get hyper when around kids at a young age.

i think the broholmer is a very rare and not to easy to Get dog ?

A boerboel is calmer around the house then a cane corso, but when they need to protect they can be harder to handle then a cane corso.

As gary said, can we hear a bit more about you area and living situations.
