Friends, I am new to the Caucasian Ovcharka fan club but nevertheless have been a molosser fan since long. I have always been interested in gaurd dogs of supreme ability and know that the CO is not for the first time owner. I am currently the proud owner of a Bhotia Mastiff more broadly called the Do Khyi.As many may know it is a variant of the Tibetan Mastiff although have learnt that a pure Tibetan mastiff is very difficult to find, perhaps only in China and Tibet. I would be interested in having a gaurd dog in the near future and wish to start researching gaurd dogs well in advance. This brings me to contrast the majestic Tsang Khyi and the Caucasian Ovcharka. Although I have read ( on this website) that the CO is the supreme gaurd dog with superb territorial instincts , is it actually superior to the Tsang Khyi in all aspects? Although I know both breeds are fairly dog aggresive, which breed would you think is more aggresive than the other? Since both are primitive in nature, which breed would you think is more trainable than the other? ( atleast to a certain extent keeping in mind their historical splendors?) Generally speaking which would be stronger than the other ( although I know that it kindof depends on the bloodlines also and the fact that in the CO there are 4 kinds of varieties depending on regional variations) To give you all a clear picture I think I should justify the kind of dogs that I like or would be more likely to invest in the future? I have been fascinated by the dogs bred by the Sundari kennel ( breeder Jarmila Bendova who has some good Taiwanese bloodlines) and she is looking to recreate the mythical molossus of Tibet along with a handful of truly dedicated breeders in Europe in the near future). As far as CO goes, I have been fascinated by some dogs of the Petlove kennel ( in particular there is one dog who weighs 92 kg - http://www.dogbreedinfo.com/caucasianowtcharka.html breeder TA Yagodigna) and of course Boyavoy of Dikaya Staya kennel who also seems to be a huge animal. Elsewhere I noticed a CO in Ukraine who tips the scale at 127 kg....) I wish to know if these are cases where form precedes functionality or is size simply some kind of genetic ploy to increase the 'marketability' of the breed by unscrupulous breeders? I would be grateful if members can enlighten and join me in contrasting these two giant gaurdians ( if at all) from an unbiased point of view. Any information regarding the above issues would be welcome. Best wishes, Vidya :)
