I've sort of vaguely heard that name before, but just googled it out of curiosity. ...So basically someone a hundred years ago had a dog called Chinook that was a husky mix crossed with a mastiff, and he used this dog as a stud dog, and then mated him with his own pups so his traits were strong in the next pups, thus creating the all new Chinook breed? Huh. Go figure.
Anyway, to answer your question: Of course you can post a picture of her, if you so wish, post away.
