I do my own research thanks, don't want to do yours as well, you only pick out the bits that suit your limited point of view anyway such as only guard dogs bark 
Well I said Crispy was not a guard dog.
As it happened Crispy would bark until reorgnising you or hearing his name.
So doubtful any barking was long term or would travel upstairs through doors & wake people. If Crispy actually woke.
