Toilet training a puppy, including the nights

There is no trick and there is no product. Toilet training is three things done consistently: supervise, schedule, reward. In that order.

Almost every household that finds this hard is improvising the timing. Almost every household that finds it easy has put the puppy outside on a clock rather than when somebody remembers.

Most puppies are reliable in the house somewhere between four and six months, with accidents becoming rare well before that. Some take longer. Very small breeds often take longer, because the bladder is smaller.

The schedule, which does most of the work

A rough guide used widely is that a puppy can hold on for about one hour per month of age, plus one, up to a limit. A three month old puppy is therefore about four hours at the absolute maximum, and much less when awake and busy.

Do not run to the maximum. Take them out:

• First thing in the morning, before anything else
• After every sleep, including short ones
• After every meal, within about fifteen minutes
• After play, and during long play
• Last thing before bed
• Every hour or two in between while awake, in the first weeks

Set a phone timer if you need to. Everyone thinks they will remember and nobody does on day three.

The method, in full

1. Take them out on a lead, to the same spot. Even in a fenced yard. Carrying a young puppy out avoids an accident on the way
2. Stand still and be boring. No playing, no talking. Playing turns the trip into a game and the toileting gets forgotten
3. Wait. Up to five minutes. If nothing happens, go back inside, watch closely, and try again in ten minutes
4. Reward immediately when they finish. Immediately means within a second or two, outside, while they are still in the spot. A treat and genuine praise. A reward given back inside rewards coming inside
5. Then play, if you are going to. Play after toileting also stops a puppy learning that finishing means going straight back in

Use a phrase as they go, the same one every time, said quietly. After a few weeks most puppies will go on cue, which is useful at 11pm in the rain and before a car trip.

Supervision is the other half

An accident indoors is not a training failure, it is a supervision failure. A puppy that is loose and unwatched will have accidents, and every accident makes the spot more likely to be used again.

• Watch, tether or confine. If the puppy is not being actively watched, it is behind a gate, in a pen, or attached to you by a lead
• Learn the signals. Circling, sniffing in a line, sudden disengagement from play, heading for a corner or behind furniture. Once you know them you get thirty seconds of warning
• If you catch them starting, interrupt gently with a noise and take them straight outside. Do not shout
• Clean with an enzymatic cleaner, not a general household cleaner. Normal cleaners leave scent markers a dog can still smell, and that scent says “this is the spot”. Avoid anything ammonia-based, because ammonia smells like urine
• Expect a lot of washing. Bedding, towels and mats go through the machine constantly for a couple of months, and a run of warm loads is exactly how a machine starts to smell. One hot cycle a week handles it, and why the washing machine smells covers the rest

Never punish an accident, including the old business of rubbing a nose in it. It does not teach the puppy where to go. It teaches the puppy to toilet where you cannot see, which is behind the couch, and it makes a dog reluctant to go in front of you outside. This is the single most counterproductive thing a household can do here.

Pads, and why a house with a back door should skip them

Toilet pads solve an apartment problem. If you have a yard and a door, they mostly create work.

A pad teaches a puppy that toileting indoors on a soft absorbent surface is correct. The next step is teaching them it is not, and they generalise from pad to bath mat, to rug, to the pile of washing.

Use pads if you are in an apartment, on an upper floor, or the puppy cannot go out yet on veterinary advice. Otherwise go straight outside.

If you have used pads, move them progressively closer to the door, then outside the door, then remove them.

The nights

Expect one or two wake-ups for the first few weeks. A young puppy physically cannot last a whole night.

• Last toilet trip as late as you can manage, and take up the water bowl about an hour or two before bed. Not longer, and not on a hot night
• Sleep near the puppy for the first week or two. A crate or pen in your bedroom means you hear the stirring before the accident, and the puppy settles faster because it is not alone
• Set an alarm rather than waiting to be woken. Four or five hours after bedtime, take them out, boring and quiet, straight back to bed
• Keep night trips businesslike. No lights on more than needed, no play, no conversation. The night trip must not be more interesting than sleeping
• Stretch it gradually. Push the alarm later by fifteen or twenty minutes every few nights

Crying at night in the first week is usually about being alone rather than needing to go out. That is the case for having them in the room, and it is the same reason a crate works better as a bedroom than a box.

Regression, which is normal

Almost every puppy goes backwards at some point: a new house, a change of routine, a week of rain, adolescence around six to twelve months.

Go back to the schedule and the supervision for a fortnight. It usually resolves as quickly as it appeared.

Wet weather is its own problem. A puppy that does not want to go out in rain will hold on and then go inside. Stand out there with them under an umbrella, use a covered spot if you have one, and expect a bad week during a wet stretch.

When it is a vet question rather than a training question

Some of this is not behaviour, and the distinction matters:

• Suddenly going much more often than before
• Straining, or producing very little
• Any blood
• A dog that was reliable and is suddenly not, with no change in routine
• Drinking noticeably more than usual
• Accidents while asleep

Those are veterinary questions, not training ones, and this article deliberately stops there. A puppy that has regressed for a physical reason will not respond to a schedule, and the longer that runs the harder both problems get.

The short version

Timer on the phone. Outside on a lead to the same spot. Boring until they go, then reward instantly, outside. Watch or confine the rest of the time. Enzymatic cleaner on accidents and no punishment ever. One alarm at night, stretched later each week.

Do that and most puppies are largely reliable within a couple of months, which is faster than doing something clever inconsistently.

The rest of the first weeks, including what the house itself needs to survive, is in puppy-proofing a house and garden. And if the puppy is also chewing everything in reach, that is a separate and equally normal problem covered in stopping a dog destroying things.
