Bella is 29 months old and she will go to the bathroom in the house...I find if I put her in the bathroom with her pads and bed and water/food when I go out she will use the pads but if she needs to go during the night and I don't hear her get out of my bed...my sewing room will be her target LOL I have just accepted it as I really do not want to crate her at night...I toilet her right before bed and for the most part...she waits until morning.
