How to Potty Train a Puppy

Puppy potty training comes down to three habits. Take your puppy out on a schedule, reward them the moment they go in the right spot, and supervise closely so accidents have little chance to happen.

Never punish an accident. Clean it up and take them out sooner next time.

Most of the work happens in the first few weeks. Here is what the veterinary guidance says about each step, and why it works.

When can a puppy start potty training?

Right away. The Merck Veterinary Manual puts the first age at which a dog can choose to hold it at 8½ weeks. That means training can start as soon as your puppy is home.

Merck describes housetraining as two jobs. One is teaching a preference for a surface or place, such as grass. The other is teaching the puppy to hold it until they get there.

Here's a surprising detail. Merck notes that puppies raised in pet-store cages are usually harder to housetrain, because they never had to hold it. If your puppy came from one, give it extra patience.

How long can a puppy hold it?

Less time than you might hope, and it grows as they do. Merck's owner guide says that as puppies age, they can go longer without needing to go and won't need to go out as often.

A common rule of thumb comes from Dr. Mark Stickney at the Texas A&M College of Veterinary Medicine. He suggests one hour per month of age. A three-month-old puppy would go out about every three hours.

Treat that as a ceiling during the day. AAHA's behavior guidelines note that puppies with small bladders and fast metabolisms may still need to go out hourly, even once they are trained.

Nights take longer. AAHA says it may take several months before a puppy can reliably hold it through the night.

What does a good potty schedule look like?

Puppies go at predictable moments. Merck's owner guide lists them:

  • first thing in the morning
  • last thing at night
  • after meals, and after drinking a lot
  • after waking from a nap
  • after playtime
  • during the night, for very young puppies

Merck adds a useful window. Taking a puppy out 15 to 30 minutes after eating, and straight after play or waking, can speed things up.

Regular meal times make the whole day easier to predict. AAHA recommends set meal times, and our guide on what to feed a puppy covers how often.

Watch for the signals

Puppies tell you before they go. AAHA and the ASPCA both mention sniffing and circling. The ASPCA adds walking with stiff back legs.

Merck lists standing near the door and slipping out of your sight. If you see any of these, head outside straight away.

How should I reward my puppy?

Straight away, while they are still in the spot. Merck's guidance is to reinforce elimination immediately with a food reward, outdoors, in the place you have chosen.

The ASPCA encourages real enthusiasm: praise, affection and something tasty. AAHA prefers gentle, calm praise plus a small reward. Either style is fine. The timing matters more: Merck says the reward should come immediately.

AAHA's guidelines explain the reason. Behaviors that are rewarded are repeated, and new behaviors are learned best when they are rewarded every time.

Take your puppy to the same spot each trip. AAHA's new-dog checklist recommends a consistent location for elimination.

What should I do when my puppy has an accident?

Accidents will happen. AAHA says plainly that they are not the puppy's fault. It helps to hear that on a hard day.

If you catch your puppy mid-accident, make a neutral sound, such as a clap, and take them outside. Merck recommends exactly this, then a reward when they finish outdoors.

If you find a puddle later, simply clean it up. The ASPCA points out that a dog learns nothing from being scolded for a past accident, even one a few minutes old.

Why punishment backfires

Merck explains that punishing a puppy caught in the act can make them afraid to go in front of you, which gets in the way of housetraining.

Rubbing a puppy's nose in it is the classic mistake. The ASPCA warns that the puppy concludes you dislike pee and poop, and may simply get sneakier about hiding it.

The wider evidence points the same way. AAHA's behavior guidelines oppose aversive training methods. AVMA's news service reported the American Veterinary Society of Animal Behavior position that reward-based training carries the most advantages and least harm.

How to clean up properly

Clean quickly and completely, as Merck advises. Dr. Stickney at Texas A&M adds the reason: removing the smell stops the puppy returning to the same spot.

The ASPCA recommends an enzymatic cleaner made to neutralize pet odors. It also warns against ammonia-based cleaners. That advice is written for cats, and the reason given is simple: urine contains ammonia, so an ammonia cleaner can draw the animal back to the spot.

ASPCA Poison Control also advises letting a shampooed carpet dry before pets walk on it.

Do puppy pads help?

They can, depending on your home. Merck lists an indoor toilet area, such as paper or an indoor puppy potty, as one option for the hours when nobody can supervise.

Merck places that toilet area inside the space where the puppy stays while you are out, such as a pen.

Keep Merck's two-part definition in mind, since half of housetraining is building a preference for a surface. If outdoors is the long-term goal, reward every outdoor success too.

The ASPCA's advice on rewards covers both routes: whether the goal is pads indoors or grass outdoors, celebrate each success. In the veterinary sources we checked, we found no study comparing pads with outdoor-only training, so neither route has been shown to be faster.

Where does a crate fit in?

A crate is a tool for the times you cannot watch. Merck recommends confinement to an area where the puppy won't eliminate, such as a pen, room or crate where they eat, play or sleep.

Supervision still does most of the work. AAHA calls keeping your puppy in sight the single most important factor in housetraining.

Our guide on puppy crate training covers size, first steps and how long a puppy can stay inside.

Call your vet promptly if your puppy:

  • was reliably trained, then starts having accidents again
  • seems uncomfortable or strains when peeing or pooping
  • is peeing much more often, or in larger amounts
  • dribbles urine without seeming to notice

Merck notes that any medical problem causing more urine, more frequent trips, discomfort or loss of control has to be ruled out before house soiling is treated as a training issue.

Questions new puppy parents ask

How long does puppy potty training take?

Merck's owner guide says it usually takes a few weeks with patience and consistency. AAHA adds that holding it through the night can take several months.

Should I wake my puppy at night to go out?

AAHA says you will need to get up for night-time breaks in the early weeks. If you use a crate at night, AAHA suggests keeping it close to your bed so you hear when they need to go.

Is it okay to use puppy pads and go outside too?

Merck lists an indoor toilet area as one option for unsupervised hours. Reward outdoor trips every time if outdoors is the long-term goal.

What if my puppy won't go outside?

Stay out with them and give them time, as Dr. Stickney at Texas A&M advises. Merck lists rain, fireworks and neighboring animals as things that can put a dog off going outside.
