It's actually quite amazing how different the dogs are in different parts of the world. I couldn't possibly vouche for the existence of any of those breeds, but I could see it as being possible. I know that I stayed in Spain for 2 weeks a few years ago and was very shocked at the dogs I encountered when I was there, and even how different some of the very common dogs here were there... I frequently encountered a relatively small black dog with a white stripe down it's chest, and when I finally decided to ask somebody what kind of dog it was they told me it was a Black Lab, which left me stunned. Very pleased to see a large amount of Mastiff-type dogs on the list though!!
