I also expect piddle accidents when its raining
My older yorkie Belle is trained to go outside and the other two are pee pad trained. Belle does not like to get out in the rain or the snow so she tends to hold it as long as possible. I'm trying to get her to go on the pee pad too but that is a long and slow process...altohugh I haven't given up hope yet. She went on the pee pad two nights ago out of the blue. I'm hoping she learns this good habit from the pups. *fingers crossed*
