With my 2 dogs, we used the bell trick to let us know when they need to go to the bathroom. I have some bells hanging from the doorknob on my backdoor. Whenever they need to go out to use the bathroom, they will ring the bell to let us know. Keep in mind that you only ever use the bell to take your dog outside to relieve itself. Never let the dog ring the bell and then take them out for a walk even if they relieved themselves first. Always take them back inside to enforce that the bells are only for using the bathroom. I can go into more detail on how I trained my dogs on this in more detail if you like.
