Difference between Pyrenees Mountain Dog and German Shepherd?

There may be some confusion concerning the name Pyrenees Mountain Dog. The Question is confusing in that the Great Pyrenees (http://en.wikipedia.org/wiki/Great_Pyrenees ) is an AKC breed and the Pyrenean Mountain Dog is the British name. (http://www.pmdc.org.uk ).

(GP = Great Pyrenees PMD= Pyrenees Mountain Dog ) basically the same dogs.
