To which I'd add:
Dogs don't seem to have the necessary memeory or ability for analogical
reasoning to be memetic vectors. Chimps might, but without human guidance,
I doubt that any replicators that made their way through chimp meme-space
would be sufficiently complex or representational to qualify as memes in
any interesting sense.
