16-Week Puppy Potty Schedule

At 16 weeks (4 months), most puppies show noticeably better bladder control than at 8–10 weeks.

Daytime Frequency

Breaks can typically stretch to every 2.5–3 hours, still anchored around meals, naps, and play sessions.

Overnight

Many 16-week puppies sleep through the night, though some still need one break, especially if bedtime is early or water was given late.

Watch for Regression

Stress, a new environment, or illness can cause temporary setbacks — this is normal and usually resolves by returning to a consistent schedule.
