Anatolian Shepherd questions Questions

I am dealing with expanding my sheep herd and will be needing a livestock guard dog.
Great Pyrenees is one option. However, many of those I have experience with have a strong tendency to roam miles from home. I need this dog to stay with the herd at all times.
Anatolian Shepherds have attracted my attention. I like their shorter hair coat and appearance. My question- do they have the urge to roam like Great Pyrenees dogs?
