How to Potty Train a Puppy in an Apartment
Potty training a puppy in an apartment uses the same core method as a house with a yard, a fixed schedule and consistent praise, but the logistics of elevators, hallways, and lease...

A certified puppy trainer breaks down a realistic, week-by-week puppy crate training schedule, from the first 8-week sessions to overnight stretches by 4 to 5 months, grounded in bladder-capacity guidance from AKC, ASPCA, and Ohio State's veterinary team.
Every new puppy owner asks a version of the same question during week one: how long can I actually leave my puppy in the crate, and when. A clear crate training schedule takes the guesswork out of that first stretch, so you're not leaving the puppy in too long or letting stays run too short to matter. I coach new puppy families through this stage all the time, and I'm living it again right now with Finch, my six-month-old Goldendoodle, who went through a version of this same schedule.
Crate training works through a series of small, timed wins that build a puppy's bladder capacity and comfort at roughly the same pace, so house training and crate training finish together instead of fighting each other. It has little to do with closing a puppy in a box and hoping for the best. Below is the schedule I hand to clients, the bladder-capacity math behind it, and what to do when a puppy pushes back.
Most puppies start structured crate sessions around 8 weeks, held 30 to 45 minutes at a time, and reach 3 to 4 hour daytime stretches by 4 to 5 months. A puppy can typically hold their bladder about one hour per month of age, plus one. What makes the schedule work is short, positive sessions, not raw hours logged.
Before you can build a schedule, it helps to know the physical limit you're working with. A widely used rule of thumb, repeated by trainers and included in the ASPCA's crate training guide, is that a puppy can typically hold their bladder for about one hour for every month of age, plus one. An 8-week-old puppy is roughly 2 months old, which puts them at 2 to 3 hours in theory, though in practice most young puppies need a bathroom break well before that ceiling, especially right after eating, drinking, waking up, or a play session.
The Ohio State University Indoor Pet Initiative's crate training guidance makes a similar point: the goal in the first few weeks is to keep every crate stay well inside a puppy's comfort zone, rather than testing the outer limit of how long they can hold it, so the crate stays linked to rest. That comfortable stretch is the number to build a schedule around, well short of the theoretical maximum.
| Age | Approx. max hold time | Realistic daytime crate stretch |
|---|---|---|
| 8 to 10 weeks | 1 to 2 hours (theoretical) | 30 to 45 minutes |
| 10 to 12 weeks | 2 to 3 hours | 45 to 90 minutes |
| 3 to 4 months | 3 to 4 hours | 1.5 to 2.5 hours |
| 4 to 5 months | 4 to 5 hours | 2.5 to 3.5 hours |
| 6 months and up | 6 to 8 hours | 3 to 4 hours (still not an all-day stretch) |
The first two weeks focus on making the crate feel unremarkable rather than on duration. The American Kennel Club's crate training guide recommends feeding a puppy's meals inside the crate during this stage, with the door left open whenever you're home to supervise, so the space becomes linked to something good instead of separation. Keep sessions to 30 to 45 minutes, timed right after a potty break. Never crate a puppy as a response to a mistake. Building this association without force lines up with the AVSAB's position statement on puppy socialization, which stresses that early experiences that feel safe and rewarding shape a puppy's long-term comfort more reliably than repetition alone.
Once a puppy settles into short sessions without much fuss, start adding real absences. Step into another room first, then move to stepping outside, and work up to a short errand. Daytime stays can stretch to 45 to 90 minutes. This is also a reasonable point to start actual overnight crate use, with the expectation of at least one nighttime bathroom trip. A crate placed near your bed at this stage makes those wake-ups faster and calmer for everyone.
Bladder control improves noticeably here. Many puppies can sleep 5 to 6 hours before needing a break, and daytime stays can reasonably reach 1.5 to 2.5 hours. This is not the stage to start using the crate as an all-day solution while you're at work. A puppy this age still needs a midday break, a walk, or a sitter, since their body can't yet manage a longer crate stretch than that.
By this point the crate should start to feel like a choice rather than the only option. Daytime stays can reach 2.5 to 3.5 hours, and many puppies will nap there voluntarily with the door open. The goal from here on is consistency, rather than pushing the ceiling higher simply because the puppy can technically handle it.

| Week | Daytime crate goal | Overnight expectation | What's new |
|---|---|---|---|
| 8 to 10 | 30 to 45 min, 3 to 4x/day | 1 to 2 wake-ups | Meals fed in crate, door open when supervised |
| 10 to 12 | 45 to 90 min | Usually 1 wake-up | Short absences from the house |
| 12 to 16 | 1.5 to 2.5 hr | Often sleeps through | Crate moved to its final location, if desired |
| 16 to 20+ | 2.5 to 3.5 hr | Sleeps through | Crate becomes an optional daytime retreat |
Crate training goes faster when the minutes right before it are spent tiring out a puppy's brain as well as their legs. A puppy who just worked through a snuffle ball or gnawed on a teething ring settles into a nap far more easily than one who's still buzzing with zoomies. Rotating a few purpose-built toys before a crate session is a small habit that pays off during the witching hour especially, when overtired puppies are hardest to settle. Our bamboo puppy play gym is built around exactly this idea: seven toys, each with its own job, so a five-minute session before crate time actually does something.
A simple routine works better than a complicated one: crate for rest, gym for supervised awake time. Puppies who get a predictable stretch of enrichment before every crate session tend to settle faster and protest less, because their body already knows what's coming next. Keeping the two spaces distinct, one for sleep, one for play, also helps a puppy learn the difference between downtime and active time, a skill that carries into adulthood.

If you're setting up a new puppy's routine from scratch, pairing a consistent crate schedule with a dedicated play space, like the Nurtino bamboo puppy play gym, gives both halves of the day a clear job instead of one long stretch of unstructured time.
As a rough rule of thumb from the ASPCA, a puppy can typically hold their bladder about one hour for every month of age, plus one. An 8-week-old puppy tops out around 2 to 3 hours in theory, though most need a break well before that, especially after eating, drinking, or playing. By 6 months, many puppies can comfortably manage 4 to 6 hour daytime stretches.
Start with short 30 to 45 minute sessions, 3 to 4 times a day, with the door open when you're home and supervising. Feed meals inside the crate to build a positive association, and always take a potty break right before closing the door. Overnight, expect at least one wake-up for a bathroom trip at this age.
A light cover over the top and sides can help a puppy settle by reducing visual stimulation, as long as airflow stays open and the puppy isn't showing signs of overheating or distress. This step is optional rather than required. Some puppies settle faster with a covered, den-like crate; others do better with it fully open, so watch how your individual puppy responds.
Most puppies reach a comfortable overnight routine within 2 to 4 weeks of consistent use, though full daytime independence, sleeping through the night and settling calmly during longer absences, usually lines up closer to 4 to 5 months as bladder capacity and confidence both catch up. Consistency matters more than speed here.
Used correctly, a crate is a safe resting space rather than a punishment, and most veterinary behavior sources support crate training as a normal part of raising a puppy. What makes it uncomfortable is misuse: crating for punishment, leaving a puppy in far longer than their bladder or brain can handle, or skipping the positive association steps that make the space feel safe in the first place.
