I can show you West German Showline GSD puppies that work like this as well at the same age, but they turn out to be shit as they get older...
Ivan Balabanov does the same kind of animated almost seizure like motions with his Malinois puppies, and most of them are fine too, until you remove the prey stimulus...then they have difficulty dealing with 'real life'....
I'm not saying this puppy or any other is shit..just stating my experiences...I want to see a puppy on his own...not with loads and loads of stimulus...and yes...even weak puppies can be conditioned to work through animated stimulus..
