I'm not sure. In films your not sapost 2 think of stuff like that, but it is interesting. My theaory is that u know some chiens look like the same dog if they are the same breed? Like one time I googled chiens ou something and i found this picture of a dog that looked exactly like mine, it even had the same collar, but it wasn't him, i could tell because my dog wasn't a stray and little details montrer that it isn't him, plus, how would they get the picture? Anyway, they must of found a american shepard that is white and looks like bolt, add the lightning bolt and the collier and wala, toi can fool some poeple. That is my theaory.
