We all know how smart Goldendoodles are so why not extend their training to ring a bell to go out?  From the Two Belles Website: "At Two Belles, we have designed a unique training bell that we feel makes it easier for you to train your puppy or dog in a shorter amount of time and makes it easier for your pet to understand what is expected. Because we want your dog to learn to ring the bell ONLY when there is a need to go outside, our training bell comes with a hook to hang it by the door -- not on the door. By hanging the training bell by the door, we hope this eliminates confusion in your pet because the bells won't ring every time the door opens/closes -- hopefully making it easier to train your puppy or dog to understand that by ringing the bells you will open the door for a potty break. In addition, by using the hook provided, you can place the training bell at a level comfortable for your dog to use no matter how big or small."
