House-training timetable
Enter your puppy's age in months, your wake and bed times and the meals a day for a starting schedule of breaks with clock times. For an adult dog, leave the age blank. Pre-filled from your setup.
This timetable is built from published rules of thumb. Puppies vary, and the sources say so. Run it for a week with the potty log; where the log and the table disagree, the log wins. Accidents in a dog that was reliable, blood, straining, or drinking more than usual are questions for a veterinarian before they are training questions (House training).
How to read the schedule
- Every break row is a trip outside with the dog on leash, to the same spot, with a reward as the dog finishes. Penn Vet's behavior service gives the reason for going along: you can only reward what you see.
- "Interval break" rows fill any gap longer than the interval. A puppy that has just played, drunk or woken from a nap goes out then, whatever the table says.
- Meal rows are placeholders. The table spreads meals evenly from half an hour after waking to three hours before bed. That placement is our assumption, not a source's rule. Move the meals to your real times and keep the break 15 to 30 minutes after each one.
- The overnight row appears for puppies under five months, without clock times because the age rule is a rough guide. Take the puppy out only if it wakes and stirs; a puppy that sleeps through is fine to leave asleep.
- The break count is compared with the outings-per-day table in UC Davis's house-training handout (a handout written by veterinary students for the school's behavior service). A count well outside that range usually means a meal or a nap is out of place.
Assumptions behind the numbers
| Rule | What the source says | Source |
|---|---|---|
| Holding interval | About one hour for each month of age, give or take an hour; adults out about every four hours when possible, and able to hold 8 hours or longer in general | Ohio State Indoor Pet Initiative; Penn Vet |
| Holding interval, second version | About as many hours as the puppy's age in months, up to about nine months to a year | AKC |
| Breaks while awake | Every one to two hours, every half hour during active play, and at least every four hours even when resting | VCA; AKC |
| Breaks while awake, second version | At least every two hours, and after waking, play, eating and drinking | Humane World for Animals |
| After meals | 15 to 30 minutes after eating | Merck Veterinary Manual |
| Overnight | Overnight outings may be needed until about five months; most puppies can sleep about seven hours | VCA; Humane World |
| Inactive adult | A healthy adult holds urine about three to four hours when inactive | VCA, house soiling |
| Outings a day by age | 6 to 14 weeks: 8 to 10; 14 to 20 weeks: 6 to 8; 20 to 30 weeks: 4 to 6; 30 weeks and older: 3 to 4 | UC Davis handout (student-written) |
| Meals a day | 8 to 12 weeks: four; 3 to 6 months: three; 6 months to a year: two; adults: usually one | ASPCA |
| Time alone longer than the interval | A person comes in for a break, or the puppy has a pen or gated room with a toileting surface instead of a crate | Ohio State; VCA |
The table uses two hours between breaks for puppies under six months and four hours from six months on. Where the sources give a range, we chose the end that keeps a young puppy out more often. Convention

Biscuit is 10 weeks old (2.3 months) on October 12, 2026. With a 6:30 a.m. wake time, a 9:30 p.m. bedtime and four meals, the table gives ten breaks: on waking, after each meal, at 9:20 a.m., 1:10 p.m., 5:00 p.m. and 8:05 p.m., and before bed, with one overnight trip, perhaps two, if she stirs. UC Davis's handout gives 8 to 10 outings for her age. Her holding interval is about 2.3 hours (1.3 to 3.3). The Nakamuras are out six hours on weekdays with a dog walker at midday, which makes two stretches of about three hours, each longer than her interval. Open: whether the walker can add a second midday visit while Biscuit is under four months. The walker settles it; until then, a pen with a toileting surface stands in for the crate on weekdays.
House training teaches the routine around this table: going out with the dog, the elimination cue, supervision and confinement between breaks, and what to do about accidents.
