Hi Justin
Gordon is correct.
My rescuer pack (pictured at the bottom of my first post) comes with a German Shepherd with a bonafide, removable collar.
If you're collecting G. Shepherds for the reason I suspect (Roman), you might share my disappointment at Playmobil's lack of a really believable mastiff. The wolfhound looks more like a cocker spaniel than the sort of dog that could pull wagons and tear off a hand. The sanuki (sp?) with the new Egyptians (a black dalmation) is close to Greyhound quality at least. (The Romans I think had a dog similar to the greyhound).
