How do I house-train (potty train) a puppy?

Short answer

House-train with a consistent schedule, close supervision, and immediate rewards. Take your puppy out first thing in the morning, after meals, after naps and play, and before bed; the moment they finish outside, praise and reward right away. Clean indoor accidents with an enzymatic odor-eliminating cleaner, and never punish accidents — especially after the fact, which doesn't help.

Who this is for

Owners house-training a puppy or newly adopted dog with reward-based methods.

When this doesn’t apply

Sudden loss of house-training in a previously trained dog, which may be medical — see a vet
A fixed guarantee of timing; puppies mature at different rates

Step by step

Set a consistent schedule
Take your puppy out first thing in the morning, after every meal, after naps and play, and before bed. AKC calls a consistent house-training schedule critical to success.
Go to the same spot and wait
Bring your puppy on leash to a chosen potty area and give them time to go, so the location becomes a cue.
Reward the instant they finish
Praise enthusiastically and give a treat immediately after they eliminate outside, so they connect the reward with going in the right place.
Supervise and confine between trips
Watch closely indoors, and use an appropriately sized crate — just big enough to stand, turn around, and lie down — when you can't supervise.
Clean accidents thoroughly
Use an enzymatic cleaner that eliminates odor so your puppy isn't drawn back to the same spot. Clean up calmly without scolding.

Normal, or time to call the vet?

Normal — carry on

Occasional accidents are a normal part of house-training, especially in young puppies still gaining bladder control.

Keep an eye on it

Track the pattern — with a consistent routine and supervision, accidents should become less frequent as your puppy matures.

Book a vet visit

If a fully house-trained dog suddenly starts having accidents, or a puppy keeps having them despite correct training, see your veterinarian — a urinary tract infection or other medical issue can make it impossible to hold it.

What changes the answer

Your puppy's age and bladder control
Consistency of the schedule and supervision
Whether accidents are cleaned with an enzymatic cleaner
Any underlying medical issue, such as a urinary tract infection

Common mistakes

Punishing accidents, especially after the fact — AKC says this doesn't help and can backfire
Cleaning with regular cleaners that leave odor, which draws the puppy back to the same spot
Giving a puppy too much unsupervised freedom too soon
Assuming stubbornness when repeated accidents could signal a medical problem like a UTI

Common questions

Should I punish my puppy for accidents?

No. AKC says scolding, especially after the fact, doesn't help. Clean up calmly with an enzymatic cleaner and focus on rewarding successes outside.

How do I stop my puppy returning to the same indoor spot?

Clean it with an enzymatic, odor-eliminating cleaner. Removing the scent stops the spot from cueing your puppy to go there again.

My house-trained dog started having accidents again — why?

Sudden regression can be medical. A urinary tract infection, for example, can make a dog unable to hold it. If you've done everything right and accidents continue, see your veterinarian.
