[YorkieMother]

I guess I have to ask what is she hearing to set her off at night ????

Could she be hearing something you are not? That would be a place to start. Find the trigger as it only some nights what differnt on the ones she does not to the ones she does?

Why can she not sleep in the same room??
Dogs are soical creatures they like to be near thier family.
It is ok to not let her that of course is your choice but it she be more comfortable in the room why not.

Maybe something in her health has changed or her brain wiring as she ages that she does not like being alone any more? She done now growing at three in the mental department. That is the age for most dogs they mature out mentally.

I posted in another thread a link to getting into a night time ritual maybe setting her up so everything about going to be is the same might help.
