The Puppies of Terra

Like much of Disch's work, Puppies has an odd, almost bizarre feel to it.
Powerful, almost god-like, aliens have taken over the earth. They think humans make good pets and most people accept that – many happily. Call them the happy puppies.
There are some, however, who resist domestication. Call them the wild dingos. This is their story.
A quick and pretty interesting read. (Found recently in a used book store.)
