To potty train a puppy, take them outside every hour they are awake, reward within three seconds of them finishing, and confine them when you cannot watch. The commonly used rule of thumb is that a puppy can hold their bladder roughly one hour for every month of age — a three-month-old needs a break at least every three hours, and more often when awake and active. Most puppies are reliable indoors by four to six months. Accidents are a scheduling failure, not disobedience.
The five rules that do 90% of the work
Everything else is detail. These five are the training.
- Go out after every trigger. Waking up, eating, drinking, playing, and every hour in between. Those are the five moments a puppy’s bladder empties.
- Same door, same spot, every time. Carry a small puppy to the door if you have to. The route and the patch of grass become the cue.
- Reward within three seconds. Not when you get back inside — that rewards coming inside. Treat and praise the moment they finish, outside, on the spot.
- Supervise or confine, never neither. A loose, unwatched puppy in a house is an accident that has already happened. Crate, pen, or a leash clipped to your belt.
- Never punish an accident. A puppy scolded for peeing learns to pee where you cannot see — behind the sofa, in the spare room. Clean it with an enzymatic cleaner and take the blame yourself.
The week-by-week schedule
Here is what a realistic progression looks like for a puppy who comes home at eight weeks. Adjust for your dog — small breeds have smaller bladders and often take a few weeks longer.
| Age | Daytime break interval | Overnight | What to expect |
|---|---|---|---|
| 8–10 weeks | Every 45–60 minutes awake | 1–2 wake-ups | Frequent accidents. Entirely normal. |
| 10–12 weeks | Every 1–2 hours | 1 wake-up | Starting to head for the door on their own |
| 3–4 months | Every 3 hours | Often through the night | Accidents drop sharply |
| 4–6 months | Every 4–5 hours | Through the night | Most puppies are reliable indoors |
| 6 months and up | Every 6–8 hours | Through the night | Occasional lapses with routine changes |
Why crate training makes this faster
Dogs avoid soiling the space they sleep in, and a correctly sized crate turns that instinct into a training tool. Correctly sized is the catch: the crate should be big enough to stand, turn around and lie down flat, and no bigger. Too much room and a puppy will simply designate one end as the toilet, which defeats the point. Most wire crates come with a divider panel for exactly this reason — move it out as they grow. Our best dog crates of 2026 guide covers sizing in detail.
A crate is a bed, never a punishment. Feed meals in it, throw treats into it, leave the door open when you are home. A puppy who resents the crate will hold it until they are released and then go immediately — the opposite of what you want.
Night-time, specifically
Pick up the water bowl about two hours before bed, take a last trip outside right before lights out, and put the crate in your bedroom. The bedroom part matters: you will hear the shuffling and whining that mean now, and you will catch it in time. Take them out, do it in near-silence with no play and no chatter, and put them straight back. Any fun at 3am and 3am becomes a fixture.
Common mistakes
- Using pee pads and expecting outdoor training. Pads teach a puppy that going indoors is fine. If you live several floors up and genuinely need them, that is a real trade-off — but expect a second training phase later.
- Cleaning with ammonia-based products. Ammonia smells like urine to a dog and marks the spot as a toilet. Enzymatic cleaner only.
- Free-feeding. Meals at set times mean predictable output. Scheduled feeding is half of scheduled toileting — our dog feeding chart by weight has portions and timings.
- Rewarding at the back door. The treat has to happen outside, at the spot, immediately.
- Assuming regression is backsliding. A sudden return of accidents in a trained puppy usually means a urinary tract infection or a routine change. Ask your vet before you re-train.
While you are at it: the escape risk nobody plans for
Potty training is the period when your front and back doors open more than at any other time in your dog’s life. Every hour, in the dark, half-asleep, often without a lead. It is exactly how puppies end up two streets away.
We make $38 designer acrylic NFC pet ID tags, so this is an interested recommendation and we would rather say so plainly. A puppy is too young for a lot of things, but ID is not one of them — whoever finds them taps any phone to the tag and your contact details come straight up, with no app needed on their end. The engraved details on the back work regardless, and there is no subscription. It does not replace a microchip, and it is not a GPS tracker; it is the piece that works instantly in a stranger’s hands. Sizing for small puppies is covered in choosing a lightweight tag, and the rest of the first-week list lives in our new puppy checklist.

Frequently asked questions
How long does it take to potty train a puppy?
Most puppies are reliably house-trained between four and six months old, with the biggest improvement usually landing around three to four months. Small breeds often take longer — smaller bladder, same size house.
How often should I take my puppy outside?
The widely used rule of thumb is one hour per month of age as the maximum they can hold it, so a two-month-old puppy gets a break at least every two hours. In practice, take them out after every nap, meal, drink and play session as well.
Should I use puppy pads?
Only if you genuinely cannot get outside frequently — an apartment several floors up, for example. Pads work, but they teach that indoor toileting is acceptable, and you will have to untrain that later.
Why is my puppy peeing in the house after being trained?
The three usual causes are a urinary tract infection, a change in routine or household, and excitement or submissive urination when greeting people. If it appeared suddenly, see your vet before assuming it is behavioural.
How do I stop my puppy peeing in their crate?
Usually the crate is too big — use a divider so they only have room to stand, turn and lie down. Also check they are not being left in it longer than their age allows, and that it is a pleasant place rather than a punishment.
What is the best treat for potty training?
Something tiny, soft and high value that can be eaten in one second, so the reward lands right on the behaviour. Our best dog training treats of 2026 roundup compares Zuke’s, Wellness, Stewart and Fruitables.
