House training can be a frustrating time and Bichons are known for being difficult in this area.
I actually don't think paper training (or pads) is always helpful as the dog is learning that its acceptable to toilet indoors.

Does she sleep in a dog crate or does she have a free run of the house?
crate training can be a useful method because most healthy dogs will not go to the toilet in there own bed. Therefore anytime you cant watch her or at night she stays in the crate. You then take her outdoors when you open the crate.
