Toilet-training your puppy
Your puppy wees indoors because his bladder is still immature, not out of naughtiness. The method comes down to three moves: take him out often (on waking, after meals, after play), reward him warmly the moment he goes outside, and never tell him off for an accident. Reliable toilet training comes within a few months.
Why he wees indoors, and why it isn't his fault
Voluntary bladder control develops gradually over the first 4 to 6 months: a puppy can hold on for about two hours by 18 weeks, and fuller control often arrives around 6-7 months (AVSAB 2021, Merck Veterinary Manual 2024). So he may well have grasped the idea and still have accidents through sheer immaturity. An accident isn't disobedience, it's physiology. Your job isn't to stop his body from going, but to show him where: you haven't done anything wrong, you're supporting a stage of growing up.
The routine, week by week
Toilet training isn't a switch: it's built in stages, by preventing accidents rather than punishing them.
Limiter les accidents à l'intérieur pendant que les habitudes se posent
- Take him out every hour, no matter what, to head off every accident
- Reward every wee and every poo done outside
- Save the special treats for toilet training: going outside becomes the jackpot
Move on when: Il fait dehors sans hésiter dès qu'on l'y emmène
- Move to every 2-3 hours as he makes progress
- Keep the moments that matter: on waking, after meals, after play, before bed
- Aim for at least three full toilet trips a day, wee AND poo, morning, midday and evening
Move on when: Il se dirige vers la porte ou la baie quand il a envie
Des nuits de plus en plus longues, sans accident
- A last wee late on the first few nights (around midnight)
- Set an alarm every 2 hours at first, a quick wee outside with no play or excitement
- Stretch it out little by little: 2h, then 3h, 4h, 5h, watching how each night goes
Move on when: Il enchaîne la nuit (se retenir la nuit ne veut pas dire propreté acquise pour autant)
Un contrôle complet qui s'installe le plus souvent vers 6-7 mois
- Keep the routine going without easing off: consistency prevents relapses
- Accept the odd immaturity slip-up without making a drama of it
The right move, on every trip out
The same ritual, repeated, builds the habit faster than any clever trick.
Go to the same spot
Always the same place outside: his own scent invites him to go there again. If needed, a 5 to 10 metre long line lets him find his spot without feeling boxed in.
Let walking do its work
Standing still gets you nowhere: it's movement that gets things going. Walk around a little, without distracting him with play.
Mark the moment
A cheerful marker word ('yes!') captures the action.
Make it a celebration
A treat he loves and an enthusiastic voice right afterwards. Don't be afraid to lay it on thick: the more special it feels, the faster he learns that going outside is brilliant.
If he hasn't gone, try again
Head back in calmly and go out again a little later. No drama, no telling off.
After a meal, the gastro-colic reflex prompts quick elimination: often within 5 to 30 minutes in a puppy. Take him out as a matter of course within the quarter of an hour after his bowl, so you ride a natural reflex instead of being caught out by it. Meals at set times make his needs predictable.
The moments not to miss
On waking
- First thing in the morning and after every nap, straight outside without delay.
- The body lets go quickly once the puppy is up and moving.
After meals and play
- Within 15 to 30 minutes of eating.
- The excitement of play speeds up the urge too: take him out as soon as it winds down.
If you catch him in the act
- A clap of the hands or a bright 'let's go out!' to catch his attention, never a sharp 'no' over the act of going.
- A 'no' over toileting teaches him to hide to go, not to wait until he's outside. Take him out to finish and praise him there.
The excited wee when you come home
- A few drops when he greets you is emotion spilling over, not a toilet-training fault (it usually fades away by around 6 months).
- Open the door, put your things down, ignore him for a minute, then greet him calmly.
Cleaning to break the cycle
His nose picks up urine long after yours has given up: a floor that looks clean can still be a wee magnet.
What really removes the smell
What brings it back, or worse
As long as an area 'smells of wee' to him, it stays an invitation to go again. Treating the smell is part of the training, it isn't just a cleaning chore.
When toilet training stalls, think health
A puppy who was already 'there' and starts going indoors again, or who does lots of tiny wees, deserves a health check before any training work.
Keep an eye
- Lots of small wees through the day when he was already there
- New accidents in a dog who was house-trained until now
Book a vet visit
- He strains, stays in position a long time, passes very little urine
- Blood in the urine, cloudy or strong-smelling urine
- He drinks and urinates markedly more than before, in a settled way
Go now
- A male straining to urinate without passing anything: possible blockage, a life-threatening emergency
- Marked listlessness, a tense and painful belly, vomiting

Frequently asked questions
Why does my dog wee in the house?
In a puppy, it's almost always an immature bladder: reliable control comes over 4 to 6 months. In an adult dog who was house-trained until now and starts again, you rule out a medical cause first (urinary infection, a dog who drinks and urinates a lot) before talking about training.
How do you stop a dog weeing in the house?
Take him out at the right moments (on waking, after meals, after play, before bed) and reward every wee outside with a cheerful marker word and a treat. Clean up accidents with an enzymatic cleaner to break the smell that draws him. Never any punishment, never any rationed water.
How long after eating does a dog need to go?
A meal triggers the gastro-colic reflex, which pushes towards the exit what was already at the end of the line. Reckon on often 5 to 30 minutes in a puppy, 10 to 60 minutes in an adult (mostly within the first half-hour). So take him out within the quarter of an hour after his bowl.
How do you get the smell of dog wee off the floor?
Blot the fresh mess without rubbing, then use an enzymatic cleaner designed for animal urine: the enzymes break down the odour molecules, which a household cleaner doesn't. Avoid ammonia and bleach (they resemble urine) and the steam cleaner on fabrics (the heat sets the stain).
What smell stops a dog urinating in the same place?
'Repellent smells' are a weak and unreliable stopgap, and essential oils (tea tree, citrus, eucalyptus) are toxic to dogs. The real lever is the opposite: remove the smell that attracts him with an enzymatic cleaner, and reward the right spot outside.
How long does it take a puppy to become house-trained?
He can grasp the idea within a few weeks of a diligent routine, but reliable toilet training follows the maturing of the sphincters: holding on for about two hours by 18 weeks, fuller control often around 6-7 months. Be wary of the 'house-trained in 10 days' promise.
