What kinda puppies are these?

I agree with you. I don't think they even have those two breeds in them. Maybe the lab. I see no chow whatsoever in them. I think they may just be really mutts. But if I would guess which breeds they had in them I say maybe a bit of lab or some type of retriever. Maybe some shepherd mix in them. But to me they look really like mutts. I don't mean anything bad about them. I love mutts. Mutts were always the smartest dogs I've owned. But that's just my opinion.
