People in india have no TM and looking at records, no TM's is being imported to india from china atleast. Rup dyal deals with himalayan sheep dog (habsi kutta) and gaddi kutta. Yes, they looks like TM's but they are not. I am not discussing about their temprament and stuff but TM's are not the choice of indians as indians like big dogs who stands at 34-36' height. Thoug there are some pro's and cons of big dogs as well but no compromise with the choice. :D About this breed, i would suggest asking for the people who searched them in every corner of himalayaan range. they can give you clarity what exactly they are. Some TM's standing at 24-27' height, they seems the cross of chinese chow chow. which actually shows by looking at them though they looks great but Is it what we are looking for? Pleces like uttanchal (pindari glaciers), Pir panjal (J&K) and sikkim border, here you can find excellent specimen of pure blood. I am still confusing about the saying that 'pure bloodline is not available and lost''. Please share the DNA's sample :) for checking purity. The description of actuall tibetan mastiff, i have read in web books , i have seen those dogs recently and there are enough no's of such big giants. All you need to move out from your home and search them out. Say no to plane areas as they love cold and do better there. they are again not so expensive but yes, for searching them you need to spend a lot.
