I have forgotten meal time
, so I know things happen, but try to plan on potty breaks after each meal, when your pup wakes up, after naps, after playtime and any moments of great excitement, and in between.
In addition, you can teach your pup to tell when he needs to go, but don't rely on this alone. Choose a method of telling you and teach your pup. Some people use bells hanging on the door or a push bell on the floor. They teach their dogs to paw the bells to go out.
No matter what, you have to be in tune with your dog always. While still potty training, limit his freedom in your home to where you can supervise. Watch for signals like circling and sniffing. When you can't supervise, put your pup in an xpen or gated off in a small room (with an easy to clean floor).
