Well i do think that the first dog on my picture resembles the second dog on the hongkong1950's foto's.
I posted this foto because i have no idea what kind of dogs they are.
My first guesses are: the dog on the left is a sharpei
the dog on the right a ridgeback.
It could both be boerboels aswell since there are so many different lines in this breed.............and this is an old picture so.......could be...boerboel.
Well anyway i'm having a great time puzzling about this picture
bye
