When I sell a puppy I recommend feeding at 7, 12, and 5. I also recommend picking up the water by 7 PM. Then take the puppy out just before your bedtime making sure it does all of its business. Also depending on age, place the crate next to your bed and when it fusses place your fingers in the openings. Listen for the difference between "I'm lonely" and "I gotta go NOW". Best of luck.
