This is the Doctor.
Here's a book all about my faithful friend, K9.
As you know, K9 is a kind of robot dog – though he'd sooner be described as a completely-mobile, self-powered computer with multi-sensory circuits and built-in defensive capabilities!
I'll also be telling you about some other amazing mechanical creatures I've encountered on my travels through Space and Time-some have been surprisingly friendly, but others were very dangerous indeed...
This is the original 96 page paperback from 1979 - Brand New Condition but priced at a used book price....
