I believe that is a white tibetan Mastiff not a Pyr...Regardle ss the dog sure does have a big mane
It is a gorgeous dog!...& now I am interested in knowing what it is...I couldn't find anything about a white tibetan mastiff...whit
e markings but not all white...This is what I found for breed standard for the breed....Other than color it looks like a Tibetan Mastiff...Is it perhaps a Pyrenean Mastiff?
