Jowls are too droopy for a Dobe; not at all tight. And when you look - just too big. And merled-looking coat, more likely Dane. Not to mention I doubt there were that many Dobes around at that point, especially with mostly British and American passengers.
It's hard to believe that this eventualy became what we know now:
I just saw a photo of an extant Dobe who had more jowl than that Dane has.
This not that dog but it was even more 'lippy' than this one was:
It's a recessive thing, like the longer, feathered coat and white chest marks that pop up now and then.
[likely the Beauceron influence]
1912 was the year the AKC recognized them but there were a bunch here by 1908.
Still a sad story, no matter the breed.
