i was going to mention in the clerk—i'm not sure exactly when it takes place, but the humans are in even greater chaos than today, and all the dogs are clones. i guess the humans are still human, but they could easily be clones, and the society is all disintegration and drones. 

then i get a link to an article about dogs and humans coming together to turtle island 23,000 years ago from siberia—the first wave of immigrants via land bridge. so before turtle island was turtle island? it's no wonder we feel such a profound affinity with immigrants, the indigenous, and dogs.
