I don't buy it. Look like Catahoula cur mixes. Or who knows, could have been a dual-sired litter as well.
The Catahoula is bred out of the Beauceron originally. The French brought them over very early on and they were with the French settlers in the early days. I don't know if there is definitive proof, but I have some old writings alluding to the Beauce being bred with local dogs to create a hunting dog in the Louisiana Territory.
i met two beaucorons at the local dog show. really nice looking and friendly dogs. i don't know why some one would want to cross the with the gsd, but if i was looking for a pup, i would certainly look at this litter, but i wouldn't do anything to contribute or encourage future breedings like this. hopefully it wasn't a planned breeding.
I used to work for a K9 secuirty company that bred their own dogs in house. They primarly crossed the beucerons with the Dobe's and the result was a Dobe on steroids. Very intimidating looking animals. They may have done some GSD crosses but I cant recall. They kept back and bred the dogs with superior working ability and intimidating looks..lol.
I agree on the ear crop too, and I double that for Dobe's. They just look so much more serious and intent with the ears done. JMO
