Well, I cant answer for Lizmo, but IMO, AKC is the worst thing for working breeds. They loose that drive to work, in order to have perfect ears or a perfect tail. Its un-needed, and ruins the (working) breeds. Just compare an AKC Sibe to a Seppala. The Seppala performs way better, is is at the same performance level as many Alaskans. Then again, a Seppala would never win Best in Show, they look nothing like Sibes. You do have people (Karen Ramstead for example) who's dogs are both bred for show and go.
So, Chinooks, being bred orginally for sled dogs, should be bred true to sled dog standards, not show standards. The same should go for Mals and Sibes.
