I walked into the room and found Arch curled up like this today.
Occasionally we find him on his back, snoring with all fours splayed. JD calls this the car crash position - terrible I know, but very funny if you ever saw it.
This dog has better bed linen than we do.
I got this vintage eiderdown from Ebay but it was too small and too ratty to use anywhere else, so it was relegated to Archie.
