Not to sound mean or anything, but have you actually met this Indian Mastiff you are referring to in person ?
Have you ever owned one before or are you just going by what other people tell you?
There is so much on the internet about both the Bully and the Bohli Kutta, with Pakistani and Indian people arguing with each other and accusing each other of mixing the breed with Western molossers.
So much nationalism and ego involved. In situations like that I prefer to take all the info with a grain of salt.
You are very wrong when you claim many Caucasian Ovcharka's are used for dog fighting in Asia.
FCI Caucasian Ovcharka's are rarely used for dog fighting. All the pictures and video's you see are almost always either of Central Asian Ovcharka's or of the North-Caucasian Volkodav's.
Neither of them are CO's.
There is so much incorrect information about the CO on sites that are in English. I addressed all the common misconception about them here:

As for CAO's being very protective, if you knew about the breed as much as you claim you do, you would know it is hit or miss with them.
I already explain what the Turkmen people used to do with human aggressive CAO's. There is a reason why the Soviets selected CO's for guarding of prison camps & borders and not the CAO.
That is not to say there are no protective CAO's out there, yes there are. For example the famous Ukrainian training facility called Ares has worked with several incredibly protective CAO's.
But that is not how most CAO's are, i.e. some are very protective, most are not that protective and then some are not protective at all and are very friendly towards all people.
This is common knowledge within the CAO world. It all depends on the lines and the breeder.
As for your last question, this is the breeder we got our female CO from. I have absolutely nothing good to say about that breeder. Nothing.
I deeply regret for ever dealing with that breeder in the first place.
To quote Tiger's great post again "People, stop doing internet searches on the most bad-ass guard dog and get out there go to breeders go to shows and WATCH these dogs"
