Ok, so the Good Lord in his infinite wisdom decided, ok, I've got millions of years to play with, so how about I evolve a dog that looks like it ran into the back of a bus...one that looks like one of those fish they'll eventually discover right at the bottom of the ocean...and I'll make it so it can't even breathe properly, so it makes a kind of snork snork noise with every breath it takes...and then we'll see whether anyone's daft enough to actually choose one, out of all the proper dogs they could go for - you know, the ones that look like dogs, and can actually breathe...?
I mean, I love dogs, but...
