This is a non registered dog breed, not just in India but also overseas. Locating a breeder and getting a good impressive dog will not be easy rather impossible. If that is what you are looking for.
It is basically what the GSD used to be in the good old days, as far as I can understand.
I am sure people will try to fool you regarding the availability of this breed etc. so be careful. Since there is no registered official standard for this dog how do you plan to identify one and even if you do, if it is good or not.
Importing dogs depends on the country you plan to import one from, the transport cost, customs, pup cost, etc. It can be anywhere in the lakh plus bracket.
