Does anyone have familiarity with the Thai breed of dog called "Bangkaew"?

A Thai friend has one he bought in JJ Market as a little puppy and it's now full-grown and quite a handsome beast. The friend claims this breed is intensely loyal and quite protective of the master - all others beware. It's not a particularly big dog - 1/2 the size of a German Shepherd but quite tough from what I'm told. Beautiful markings on this dog too.



Cheers!
