I have told my wife after "Big Mama" (our 13-year-old Pyrenees mix) dies, our next one needs to be a Caucasian Shepherd. She wants to stay with the Pyrenees breed so, we have some haggling to do. We also have an Anatolian Shepherd/Pyrenees mix that is over 140lbs at 3 years old. and another Pyrenees mix that is about 80 or so lbs.
These dogs are and have been very protective so far, but it would not be the dogs' people have to worry about. These animals are part of our family, and we are part of their pack. Anyone who goes after them have me to worry about. The dogs are just an early warning system and a deterrent. It's my job to protect the family/pack.
The monster (Anatolian Shepherd/Pyrenees mix) looks a lot like the one pictured above because of her mix of breeds. She has the black face with light brown fur that is very thick and a tale that curls up.
