Totally agree with every point you make Rog - but still can't help but think that I'd rather have got off (always an option) than allow the dog to be stuffed into an airless overhead locker, where it might - and indeed did - die. In fact, calling the FA's bluff and saying "in that case I'll get off" would've got the CSM and Captain's attention, as the aircraft wouldn't have been able to pushback until the passenger's hold luggage was off-loaded.
