They look like husky or malamute mixes to me. Usually wolfdogs are more difficult to train, too, and the descriptions (if true) indicate that both are taking well to training/walking on leashes, etc. In the video of Weyah, I see German Sherpherd very strongly! Might not be mixed with husky, but who knows. Wolfdogs usually are pretty big, too, bigger than what those two on petfinder appear to be. Since they are rescues, how would the rescue workers know for sure they are wolfdogs? Often times rescues tag mix breed dogs incorrectly, but they do their best with the information they have (which is often very limited).
