I thought old threads like this were shut down, but it was brought to my attention that some people had asked about the dogs.
Have to say that the dogs are great. Love their intelligence and guarding instinct. All I use them for is as Livestock Guardians.
I have not had any of my dogs trained in protection work, but some others have. Their reports are of a mostly natural dog at the work, but sometimes hard headed. About what I expected.
It is thought by most that their work as an estate guardian would come completely natural.
As far as protection work, it is hard to work with their intelligence. As in an agitator that the dog knows can not get the dog to come after him. If it is someone he does not know, he will be viewed as the enemy for life.
And with their jaw strength and size, few people will put the suit on.
The thought of being hit by a 33-35", 180-220# dog does not sound like fun.
Have a trainer that wants to work with them, and may in the future.
