I do not know much about your breed. Are there any websites that you could recommend?
I agree with pretty much everything that has been said in this topic, and I particularly agree with what Tiger12490 said.
You have to meet and experience breeds you are interested in, in person first. What people write about (rare) guardian breeds on the internet is often untrue or hyped up (I wrote about all common misconceptions about my breed on dogforums).
And you have to go visit the breeder at home too.
Many times breeders will make all kinds of claims, but when you go to visit their dogs you'll realize that was not what you were looking for.
Kangals and Bully Kutta's are usually far more DA than HA, so they are not breeds I personally would recommend as property guardians.
With Central Asian shepherds (Ovcharka is a Russian word for shepherd dog) it's hit and miss; it will all depend on the lines.
As I mentioned in of the other threads before, the Turkmen people would historically cull any Alabai (this is the word the Turkmen use to refer to their subtype within the CAO breed) that would appear human aggressive during the day.
And with so many CAO's being used for dog fighting nowadays (because this is such a lucrative business in former Soviet Union), far more CAO's are DA than HA.
Another thing that's important to remember is that the LGD type of guardian breeds are usually too independent and too stubborn for most dog owners out there. They are quite different from other dog breeds out there. Plus they do require a lot of space.
So a dog owner looking for a guardian breed has to do his/her homework so they can properly chose a breed that will fit within their lifestyle.
When I look at my breed (we own two Caucasian Ovcharka's), I do feel too many bad breeders are working hard on ruining this majestic breed.
I'm not against dog shows per se, because in some countries you can't get your breeding license if your breeding stock hasn't been evaluated on a dog show at least once and rated either excellent or very good.
On top of that, I know of several CO breeders who invested a lot of time and energy into their dogs so even though their dogs do have the correct protective temperament, they can still show them.
Of course it helps that they show in places where the judge doesn't opens the dog's mouth, the owner/handler does it.
But all that requires a lot of time and effort from the breeder. Most CO breeders will then simply chose to select for the prettiest, softest of character dog so they can more easily show them.
It is much easier to score a few show tittles and then sell your puppies for a higher price because their (grand) dam/sire is Ch. GCH, CWSG etc, without any regard for health or functionality of the breed.
To only select for the protective and stable temperament, good health, score the so called Guard Duty diploma (and other certificates according to the Russian model available out there that will show your CO has a temperament that's according to the breed standard) apparently is too much effort for most CO breeders out there.
So to me it is a combination of bad breeders and dog shows that are the reason so many (working) breeds are being ruined.
I particularly don't have anything good to say about almost all CO breeders in U.S. & Canada.
Almost none of them health test or temperament test (the one breeder I think is good no longer breeds).
To make matters worse, most of them import their CO's only from the large, commercial kennels that mainly breed for looks. And this is their foundation stock...
They seem to be more focused on making money and outmaneuvering their competitors than anything else unfortunately.
So while it's easier to find a good CO in Europe, if you are new to the breed or just not very careful, you still might end up with a dog that has health or temperament issues or both.
Caucasian Ovcharka's are not suited at all for most dog owners out there, but I thought I'd write this down in regard to the OP's question.
