Just now. Two bruisers out with about twelve of the buggers, collie sort of things, all going crazy. I slowed right down, nipped through at walking pace. Then clear of the pack and laying on the power, when one attacked from behind. It was trying to bite my leg, so I kept going to get away.
Next thing the stupid animal had it's rear leg and tail right through my back wheel. Wheel locked up with leg right through the stays and tail all caught up in the sprocket.
So it was rear wheel out to sort the mess. I didn't stop to really find out the details, but amazingly it didn't appear to have broken any bones, (my superficial impression).
Owner's parting comments "Sorry my dog attacked you.." No he didn't actually say that. "You're lucky it had a muzzle on".
