So my dog was splayed out on the floor in this weird pose, and I couldn't figure out why.  I petted her; she thumped her tail and didn't move.  After messing about on the computer a bit I got their food, and then she finally tried to get up, revealing that she had somehow gotten her dewclaw stuck in the leash-ring of her collar, the wee daftie.  God knows how long she'd have stayed stuck like that, without saying anything, if it hadn't been breakfast time.
